A green comet that may never return to the inner solar system is approaching Earth. But how can you see it right now and where should you look?

C/2022 E3 (ZTF) was first spotted by the Zwicky Transient Facility (ZTF)—an astronomical survey conducted by the Palomar Observatory in California—on March 2, 2022, and is set to make a close approach to Earth on February 1, 2023, when it will come within roughly 26 million miles of us.
