Comet C/2022 E3 (ZTF), 30 Jan 2023
Discovered by the Zwicky Transient Facility in March 2022, this long period comet reached its closest position to
Earth on 1 February, and will only pay its next visit to Earth after another 50,000 years. The green coma and tail
were visible from Earth observing with a telescope. *The green colour comes from the fact that it contains diatomic
carbon (C2) which is bright in green wavelengths of light.
