Green Comet in the Northern Sky

An infrequent visitor of our night sky has arrived and can be seen particularly in the Northern Hemisphere. Officially known as Comet C/2022 E3 (ZTF), the "Green Comet" was likely last seen on Earth approximately 50,000 years ago! The sparkly spectacle gets its hue from carbon in its gas cloud surrounding the nucleus. The comet can be generally spotted in the constellation CAMELOPARDALIS the Giraffe, a rather dimly lit circumpolar constellation situated in the northern sky near the "North Star," Polaris. If Camelopardalis is in your night sky, then the comet likely is, too. The comet should remain in Northern Hemisphere skies toward the northern direction until early or mid February.
