See Jupiter and Saturn snuggle up in the predawn sky this week

The two giant planets of the solar system, Jupiter and Saturn, will snuggle up in the predawn sky this week, offering spectacular views for night owls and early risers. 

The pair had a close encounter early Monday (May 18), when they were separated by about 4.7 degrees (for reference, your clenched fist held at arm's length is about 10 degrees wide). But the cosmic duo will continue to stick together for the rest of the month, and you can catch them together in the hours between midnight and sunrise. 

To see the sky show, all you need are your eyes, a small bit of outdoor space and a clear view of the southeast horizon, which makes the activity achievable even if you are stuck in your house or apartment due to quarantine restrictions.

Jupiter will appear in the constellation Sagittarius, the archer, shining at magnitude -2.5. (Magnitude is a scale of stellar brightness, with smaller numbers indicating brighter objects and negative numbers denoting the brightest objects.) Second only to the moon, Jupiter will be the brightest object in the predawn sky. The only planet brighter than Jupiter is Venus, which rises about an hour after sunrise and dominates the evening sky, shining at magnitude -4.2. 

Meanwhile, Saturn will be just to the left of Jupiter, shining at magnitude 0.3 in the constellation Capricornus, the sea goat. The planets will be too widely spaced to fit in a telescope, but you can see them comfortably with the naked eye, or a set of binoculars.

The planetary pair made their closest approach on Monday (May 18) at 12:45 a.m. EDT (0445 GMT), just a few minutes after the two planets rose above the southeast horizon. Both planets will continue to rise shortly after midnight all week long, but if you're watching that early, it may be hard to see them in the murk close to the horizon. 

Luckily, the show continues well into the night, and as the planets rise higher in the sky they will provide a spectacular view until the growing light of dawn washes them out. To get the best view, give your eyes about 20 minutes to adjust to the darkness, and try as best as you can to get away from artificial light. (If you want to use a star chart, we recommend using a red filter on your phone, or on your flashlight.)

While the planets are reasonably close in the sky, the encounter doesn't qualify as a conjunction. To be in conjunction, two celestial objects making a close approach must also share the same celestial longitude. That said, both Saturn and Jupiter came into conjunction with Earth's moon last week

It's common for planets and the moon to come close to each other in the night sky, because all of them travel on the same apparent path in space, called the ecliptic. The ecliptic represents the plane of the solar system, or the region in space where the planets and Earth's moon orbit on a (virtual) flat disc.
