16. How we test
The best star projectors can either be used as home planetariums, projecting realistic night skies and galaxies indoors, or they can serve as soft, glowy night lights for adults or children.
Depending on the model you choose, star projectors can recreate the night sky accurately from the comfort of your own home, surrounding you with stars, constellations and double as galaxy projectors. Whether you’re hosting a space-themed party, learning about the cosmos or simply looking for a way to help you fall asleep, star projectors can do it all.
Star projectors come in different shapes, specifications and sizes because they serve various purposes. Some models are designed as night lights for children, so they are simpler and prioritize creating a pleasant atmosphere rather than realistic star patterns. On the other hand, there are highly accurate star projectors that provide a scientific representation of the night sky, giving you the experience of being inside a planetarium.
Of course, this variation means that there is a significant difference in price between different star projectors. In this buying guide, we’ve tested, reviewed and ranked a range of models at various price points, with different features, styles and accuracy levels so you can choose the perfect one for you. On a tight budget? We think the Astronaut Starry Sky Star Projector is the best budget star projector in our guide.

Best overall
✅ You want to explore the skies: There are plenty of discs available for this projector, all of which are scientifically accurate, most of which is NASA-based imagery.
❌ You're on a budget: This is the most expensive option on this list, so if you're on a budget, there are more suitable options that perform almost just as well.
❌ You just want a pretty light: For anyone who just wants a nice mood-setting light, this will likely be overkill.
🔎 Sega Toys Homestar Flux Great for recreating a realistic-looking night sky inside. It's on the pricier end of the market but the option to upgrade your disc collection is attractive. The night sky representation is about as realistic as it gets. ★★★★½
The Sega Toys Homestar Flux is a compact and stylish star projector known for its power and sleek design. It's one of the most expensive options out there but offers a lot in return. The projector uses advanced glass lenses to create realistic night skies that look bright, even in rooms that aren't completely black. It's more like having a home planetarium than a basic star projector and is highly accurate, making it a strong contender for the best galaxy projector. When you adjust the focus, you can see an impressive 60,000 stars, much more than what other projectors offer.
This globe-shaped product excels with the sheer number of distinct stars it projects, and it has some tempting science-based upgrade options. The Homestar Flux has two discs, the Northern Hemisphere and the Northern Hemisphere Constellations. One shows a starry sky with 60,000 stars while the other contains constellation labels to aid with learning. A further 17 Sega-branded disks are available to be purchased separately for around $18 a piece, and it's also compatible with Homestar Original disks.
Like many other star projectors, there's a 'shooting star' function, although, in our Sega Homestar Flux review, we explained how we'd like this to be at random intervals, or in a different place each time so it isn't as predictable. It has an automatic switch-off after 15, 30 or 60 minutes function.
There are 30 additional discs available when you visit Astrial, Sega Toys' official online store. Simulations of the aurora borealis and the aurora australis are perhaps the highlights. There is a disc that displays the planets of the solar system as well, but it is the ones that show galaxies, nebulas and other NASA-based imagery that really stand out. For example, the North America nebula as taken by NASA's Spitzer Space Telescope and the weird seven-star system called Jabbah (officially called Nu Scorpii and IC 4592) as imaged by NASA's WISE mission. You can also buy disks that simulate fireworks, 'night jellyfish' and a hot-air balloon festival.

Best multi-functional scientific star projector
✅ You want true projections: The projections are true to the date and time that you 'program' it to (if you're in the Northern Hemisphere)
✅ You're buying for your child: While it's not a toy, we think it's aimed more at the younger market who have a keen interest in astronomy.
❌ You just want something to project nice lights: If you just want an affordable little projector to set the mood of your room, you're better off saving your money and going for one of the cheaper options further down this list.
🔎 National Geographic Astro Planetarium This is a good learning tool and would make a nice space gift for a budding astronomer or someone who wants to unwind. It has great functionality, with a time and date selector and a built-in-speaker. ★★★★½
The National Geographic Astro Planetarium is a high-quality indoor planetarium for a reasonable price that accurately represents the night sky and comes with plenty of extras. There are two projection discs included; one displays 8,000 stars, and the other has guidelines for the major constellations overlaid on them. Crucially, what you see is true to the time and day you set it, as we confirmed during our National Geographic Astro Planetarium review.
Rotating the image and adjusting the focus wheel in the dark is simple thanks to the blue-illuminated buttons. The result is a bright and sharp projection on the ceiling (the optics are from the German optics brand Bresser, which makes binoculars, telescopes, and microscopes). However, stars at the edge of the projection can seem blurry. One novel feature is an optional 'falling star' mode, which projects a flashing meteor every 40 seconds, though always in the same place.
Inside the box, you'll find four educational posters, three AA batteries and a 3.5mm jack cable. This cable allows you to connect your smartphone or other audio devices to the projector's small speaker, so you can play your favorite music or sounds while enjoying the view of the stars. It can also function as an FM radio, giving you the option to listen to music or relaxing sounds while you stargaze indoors.

Best for space-themed parties
✅ You want to pair it with music: We were impressed with the musical rhythm mode, where the lights flash and dance along to the beat of the music.
❌ You want voice control: Although it's a clever little device, it can't pair with your smart home devices (Alexa/Google etc).
❌ You want scientific accuracy: It's not a scientifically accurate projection, although that said, it's the most realistic looking one we've tested and even has a full moon projection.
🔎 Aurora Borealis Northern Lights Star Projector It's highly customizable, the patterns are realistic and the music rhythm mode is impressive. Although there's no Smart capability, there are still three means of controlling the device. This is one of our favorites. ★★★★½
Once again, we're not sure what we love most about this feature-rich Aurora Borealis Northern Lights Star Projector. You can easily choose between a whopping 16.7 million Aurora colors by using the buttons on the device, the remote control that comes with it or your smartphone to control it.
This Northern Lights projector is compatible with all Android and IOS smartphones. You can customize the visibility of the stars, full moon activation and the 'Aurora Borealis' colors to suit your mood. The LED light and green lasers are adjustable from barely visible to highly vivid.
During our Aurora Borealis Northern Lights Star Projector review, we were impressed with the musical rhythm mode. It does a great job of altering the lighting display to match the 'feel' of the music, and the sensitivity of the microphone can be adjusted for a more or less powerful light display, making it perfect for parties.
We were impressed with the speaker's high-quality performance, considering its compact size as a Bluetooth speaker. You also have the option to adjust the sound settings to suit the style of music you're listening to, which is a nice touch.

Best for voice control
✅ You want voice activated: You can control this projector using your smart home devices (Alexa & Google etc), meaning you don't have to fiddle with buttons to set the mood.
❌ You want it to be scientifically accurate: It doesn't show any constellations or any type of scientific night sky projections — you'll need to pay more for that.
🔎 Encalife Atmosphere Smart Galaxy Star Projector: Although it is called a Galaxy Star Projector, like most others, this is more of a mood-setting light, showing colors and patterns that reflect galaxies and nebulas with lasers that you could associate with a starry sky. ★★★★
We don't know what we love most about the Atmosphere Smart Galaxy Projector from Encalife: The exquisite 16.7 million nebula colors to choose from or the ability to control this projector with our voice with Alexa and Google.
During our Atmosphere Smart Galaxy Projector review, we were impressed by its sleek design that's sure to delight many: it's modern and compact, which allows the user to place it pretty much anywhere in the household without ruining the aesthetic. The unit can even be adjusted to four different angles, making it flexible enough to project from your selected surface onto the wall or ceiling.
The Atmosphere Smart Galaxy Projector is super easy to use with voice control, allowing you to change colors, adjust brightness and control the speed just by speaking. You can also use your smartphone with a Smart App (for Android and iOS) to give commands. The device has a color wheel where you can choose from a wide range of tones, from cool blue to warm fiery red. However, during testing, we found that most of the 16.7 million different colors were hard to tell apart with the naked eye.
The only downside with the Atmosphere Smart Galaxy Projector is that the nebulas and stars aren't scientifically accurate. Still, we enjoyed the experience so much that we didn't feel short-changed. We were especially happy with the option to adjust both the brightness and the projection speed, which makes the device great for setting a calm environment or an energetic party scene.
The Atmosphere Smart Galaxy Projector comes with a USB power cable and attractive packaging, which would be lovely to receive as a gift.

Best budget star projector
✅ You're buying for your child: It features more of a novelty astronaut design that's primarily aimed at children, though in our experience, adults love it too!
❌ The price is too high: This is another star projector where the price fluctuates wildly — we've seen it priced anywhere from $10 to $100, we'd be happy paying anything less than $35 for it.
🔎 Astronaut Starry Sky Star Projector: A well-made novelty star projector that every kid, or space fan, will love to have in their bedroom. It isn't quite on par with other star projectors performance-wise, but it does everything we'd expect of it, given its reasonable price. ★★★★
To be honest, when we managed to get our hands on this little guy for our Astronaut Starry Sky Star Projector Review, we didn't have high expectations for this seemingly novelty item with a price that can vary greatly between online and in-store retailers. It seems that many retailers are selling it, resulting in price competition among them. However, we would consider anything below $35 to be a great deal and it's one of the best cheap star projectors on this list.
This is the only novelty-shaped item in this guide so far, and that is because, often, such things aren't very good quality — but this is an exception. While the packaging may be underwhelming and could use some improvements, the actual design and build quality of the projector itself are excellent. It has a great look that would fit well in the home of any space enthusiast, regardless of their age.
The operation of the motor is very smooth and quiet, so it would be fine as a night light to drift off to sleep. As we mentioned in our review, the lighting module seems to be the same — if just a tiny bit less impressive — as other star projectors we have reviewed, including the BlissLights Sky Lite 2.0 and the Encalife Atmosphere Smart Galaxy Star Projector. They are by no means scientific, but they can be customized using the supplied remote control to a speed and color configuration to suit you.
The only thing we didn't like was that it is powered by USB-A to DC cable, which seems a little outdated (we'd prefer USB-C), but aside from that, it would make an excellent gift for any space lover for any occasion.
| Attributes | Notes |
|---|---|
| Design | Novelty design more suited to children, but surprisingly good quality |
| Performance | Bright lights and lasers, pretty patterns |
| Functionality | Customizable settings, sleep timer |
Best for pastel shades
✅ You want a lot of customization: Although the laser 'stars' can only appear as blue or green (depending on which model you get), the clouds offer a lot of color customization through the app.
✅ You want it to be compatible with your smart device: It can work with both a Google and Alexa home device, so you can turn it on and off, and give other commands with your voice.
❌ You want it to be scientifically accurate: This projector is better for atmosphere and projecting pretty colors rather than providing any kind of scientific accuracy.
🔎 BlissLights Sky Lite Evolve The nebulas are bright and endearing, complimented perfectly by the hue of the blue/green lasers. This is a great option for anyone shopping for a mood-enhancing star projector (rather than a scientific one). ★★★½
The Evolve is the newest addition to BlissLights' lineup of 'galaxy lights' and comes with the convenient feature of being voice-controlled through Google Assistant or Amazon Alexa. This means you can easily change the ambiance of any room without getting up from your seat. Furthermore, you can connect the device to your Wi-Fi network using the BlissLights app, which we found to be more reliable than Bluetooth. This eliminates the need to keep your phone close to the device for it to work properly.
The spherical design means you have near 360-degree angling, and it comes with a 1.5 m cable, giving maximum positioning flexibility. This gives it a slight edge over the Encalife Atmosphere Smart Galaxy Smart Projector, which has similar specs but can only be used in four fixed positions.
An upgrade from the BlissLights Sky Lite 2.0 mentioned above is the inclusion of patented color blending technology. Instead of using harsh color blocks to fill a projection space up to 15ft x 15ft, the four LED lamps allow for more color possibilities, and the colors 'blend' so they look softer and give off a more pastel and relaxing yet immersive environment.
Your space (up to 30ft x 30ft) can be transformed into an ethereal sensory experience by turning on the laser 'stars' and gazing for hours at the calming changing patterns.
As we confirmed in our BlissLights Evolve review, like the Sky Lite 2.0, the operation is near silent. The Bliss Lights Sky Lite Evolve would be perfect in a gaming room, during a party, at a movie night or as a relaxation tool to unwind or drift off to sleep with. There are three models in the range available — options with blue lasers, green lasers or without lasers.

Best value rechargeable star projector
✅ You want realistic imagery: The projections from this projector are incredibly bright, sharp and high resolution, almost indistinguishable from the 'big players'.
❌ You just want something cheap to set the mood: This certainly isn't the most expensive model on this list, but if all you're looking for is a projector with nice lights to create a relaxing atmosphere, there are cheaper options that will do the job.
🔎 Pococo Galaxy Star Projector It does what it is supposed to — it projects high-quality imagery onto any surface to immerse you in the wonders of what the universe has to offer, maintaining a static picture or slowly rotating image. ★★★★
Despite some questionable word choices for their marketing, the Pococo Galaxy Star Projector is a worthy addition to this guide and it is a good rival to the National Geographic Astro Planetarium and the much more expensive Sega Homestar Flux. During our full Pococo Galaxy star projector review, we found it to be a good value star projector with decent build and projection quality.
You have the option to purchase additional discs (six for around $50) along with the two that come with it. This model strikes a balance between appealing to both children and adults, and it offers a nice color gradient paint job or a matte white finish for you to choose from. To adjust the image's clarity, simply use the focus wheel, as it may vary based on the surface you're projecting the light onto.
Control is simple, using three buttons — power, rotation and sleep timer — and it is powered by a battery which you can charge with a USB-C cable. You're not tied to a power source like with the Homestar Flux, and you don't have to keep changing the batteries as you do with the National Geographic model—again — another happy medium.
The downside of the Pococo design is that you only have 30 degrees of movement to shine the lights, though as you'll typically be shining this at the ceiling, this isn't a deal breaker.

Best for homeschooling young children
✅ Your kids are interested in space: More of a planetarium than a star projector, it's a great educational STEM toy that will help your kids learn more about space.
❌ You want more of a customizable star/nebula projector: This is more of an educational item than a mood-creating star projector, so if that's what you're looking for, there are better options.
🔎 Brainstorm Toys Deep Space Home Planetarium Star Projector A neat little STEM toy with multiple functions. Kids between 6 and 10 will love to learn more about space with this hands-on device. The three-in-one functionality of this model and a reasonable price tag make it good value for money. ★★★½
Having completed a recent Brainstorm Toys Deep Space Home Planetarium and Star Projector review, we feel that it deserves a spot in this buying guide as a great STEM toy that will captivate kids ages six and up, and, in our opinion, spark their interest in all things space-related.
It is aimed at children, and the stars aren't at all scientific like you would find on the more 'adult' Sega Homestar Flux. Still, it features a slide projector and three easy-to-handle discs containing 24 color images taken by NASA and the Hubble Telescope. Each disc has a theme; Nebulas, Spacecraft & Astronauts and Planets & the Moon.
Operation is done manually rather than digitally, but you can access additional informative descriptions of the pictures on the slides online using a provided "secret code." Given its affordable price, we think this is a great investment for homeschooling or for simply learning about space with your child.

Best for generalist projection
✅ You want a realistic night sky: It comes with two disks — one featuring a starry night sky and the other featuring overlays of constellations — both of which are correct to the time and date you're using it.
❌ You want it to have a speaker: If you want a star projector that features a speaker, you'll have to look at other options.
🔎 Bresser Junior Astro-Planetarium Deluxe This Bresser planetarium star projector, designed for kids, has true-to-life projections, a five-year warranty and is simple to operate. It has a time and date selector, a shooting star function and a sleep timer, and it ships with two disks. ★★★½
As we discussed in our Bresser Junior Astro-Planetarium Deluxe review, this star projector draws many parallels to the Bresser-made National Geographic Astro Planetarium but doesn't include an integrated FM radio or the ability to attach an audio device. The Bresser Junior can only be powered by 3 x AA batteries so buyers will likely need to grab some spares if they plan on using it long-term.
This model comes in a silver and black design and shares the same basic features and projections as its National Geographic counterpart. However, there are some noticeable differences between the two.
The same Astro Planetarium Multimedia disks are included — one featuring a starry night sky and the other featuring overlays of constellations, and it's all entirely accurate for the time and day you're using it.
The image can be rotated in its stand and moved 360-degrees using built-in motors. It works best when projected from a distance of two meters. The lens, made by Bresser, has a focusing wheel that allows for easy image adjustment. Like many star projectors, it can automatically shut down after 30, 60 or 120 minutes, which is useful if it's used by a child who wants to fall asleep under the stars in their bedroom. It also has a 'shooting star' mode, where it projects a 'meteor' every 40 seconds.
| Attributes | Notes |

| Design | Silver & black design, but dated packaging |
| Performance | Date & time feature works well |
| Functionality | Battery powered (no mains option) |
Best for portability
✅ You want something portable: This star projector is so small it could be mistaken for a flash drive. Perfect for on-the-go ambiance.
❌ You want customization: If you want to change the colors, brightness or add rotation to the lasers, then you'll want to go for a different model.
🔎 BlissLights Starport USB star projector A nice little device for adding instant ambiance to environments like parties, gaming rooms, music studios or spa rooms, but we use the term star projector very loosely. ★★★½
This is an unusual entry on our list, given that it only has one single function. That said, we have included it in this guide as an inexpensive 'faff-free' star projector, though as we discussed in our BlissLights Starport USB star projector review, we use the term star projector loosely.
It looks, feels, and works similarly to a USB flash drive, but it's not. It's a small star projector that, when connected to a USB power source, creates hundreds of laser stars in a single color (you'd need multiple projectors for different colored lasers). It quickly changes the atmosphere of a room, making it more exciting and dreamlike. Gamers will love it.
It serves no other purpose or provides any kind of scientific accuracy, but it is a discrete, affordable, high-quality device that puts out visually stunning lasers to transform your surroundings while drawing very little power.
