Mars will dazzle like an orange gem next to the moon in the night sky tonight, just hours after NASA attempts to land its latest rover onto the Red Planet.
Mars isn't ready to leave the spotlight just yet, even after welcoming three new missions this month. This afternoon NASA will finish the long journey of its Perseverance mission to Mars' Jezero Crater to study the planet's ancient past. You can watch the Mars landing live here and on Space.com's homepage, courtesy of NASA, beginning at 2:15 p.m. EST (1915 GMT). The landing is expected at 3:55 p.m. EST (2055 GMT).
Last week, the United Arab Emirates delivered its Hope mission into orbit around the rusty-colored planet to study its atmosphere; one day later, China's Tianwen-1 mission also reached Mars orbit. And tonight, Mars will make a starring appearance near the half moon in what's called a conjunction.

To catch the moon and Mars dueting in the evening sky, look south to find the moon in its half-moon phase. The moon is waxing, so its near side will become increasingly lit until it reaches full moon around Feb. 26, according to NASA.
The moon and Mars will be close enough together in the sky that they will appear to be just a few finger-widths apart, or 3.7 degrees to the celestial south, from each other.
If you're into the nitty gritty, Mars and the moon will be at their closest apparent approach in the night sky when they are at a right ascension of 03h17m20s, according to In-the-sky.org. The moon's declination will be +15°57', and Mars' declination will be +19°39'.

The conjunction will occur in the constellation Aries.
Pay special attention to the apparent size of the moon: If Earth's natural satellite appears smaller than usual, your eyes aren't playing tricks on you. The moon travels in an elliptical orbit around our planet, not a perfect circular orbit.
This changing distance between the two objects means that the moon's apparent size in the sky also varies. Tonight the moon reaches apogee, the point in its orbit when it is most distant from Earth. It's the opposite of this effect that causes what's popularly known as a supermoon.
