You may not need binoculars or a telescope to see C/2022 E3 (ZTF), the green comet discovered this past March, when it makes its closest approach to Earth in 50,000 years Wednesday and Thursday.

“Comets are notoriously unpredictable, but if this one continues its current trend in brightness, it’ll be easy to spot with binoculars, and it’s just possible it could become visible to the unaided eye under dark skies,” said Preston Dyches, a public engagement specialist at NASA’s Jet Propulsion Laboratory in Southern California.
