If you look at the night sky next month and see a small green light in the sky, don’t panic, aliens haven’t landed.
A rare green comet is expected to pass Earth this week and remain visible in the night sky for nearly a month, according to NASA and astronomers.
Comet C/2022 E3 (ZTF) was discovered last March when it was already in Jupiter’s orbit. It is distinguished by its green glow.
The comet will approach the Sun, or perihelion, on Jan. 12 and will be visible to stargazers in the Northern Hemisphere, NASA scientists said. People in the Southern Hemisphere will be able to see the comet in February.
“Comets are unpredictable, but if this one continues its current trend in brightness, it will be easily detectable with binoculars and visible to the unaided eye under dark skies,” NASA wrote in its post. “What is the matter” blog earlier this month.
The comet will move northwest across the horizon throughout January and will make its closest approach to Earth between February 1 and February 2, NASA said. At that time, the comet will be 26 million miles from the planet, according to astronomers.
Astronomical maps show that the comet will be close to Mars in about a week.
