Check Out the Comet Tonight

Back when Neanderthals lived, a green comet, named C/2022 E3 (ZTF), passed Earth. 50,000 years later, it’s passing our planet again. The comet is about 26,000,000 miles away, and tonight is your best chance to see it with the naked eye. The green color comes from gases it emits, as it passes the Sun.
