Images by other observatories confirmed this, including Hubble. When they looked at the comet in April 2020 they saw it sporting quite a grand tail, extending for about 600,000 kilometers, nearly twice the distance of the Moon from the Earth! Mind you, the nucleus — the solid part of the comet — is probably only about 4 kilometers across.

Calculations show that around that time it was losing about 80 kilograms of water ice per second. It was also shedding gases like carbon monoxide (about 50 kilos/second), carbon dioxide (7 kilos/second) and diatomic carbon (two carbon atoms bound together; at a rate of 40 grams per second).
