Green Comet C/2022 E3 (ZTF)

How, where and when to see the green comet that will make the closest approach to Earth since the Ice Age. We may be the last humans to see C/2022 E3 (ZTF), a celestial body that may never return. Since the last ice age, C/2022 E3 (ZTF), also known as Comet ZTF, has not been in our cosmic neighborhood. It was discovered in March by the Zwicky Transient Facility.
