Green Comet 2022 E3 ZTF
Green Comet 2022 E3 ZTF
C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on 2 March 2022. The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen.
The comet's systematic designation starts with C to indicate that it is not a periodic comet, and "2022 E3" means that it was the third comet to be discovered in the first half of March 2022.
The comet nucleus was estimated to be about a kilometre in size, rotating every 8.7 hours. Its tails of dust and gas extended for millions of miles and, during January 2022, a third anti-tail was visible.
