A huge comet will fly past Earth in July and you might see it

A comet first spotted in the distance in 2017 may finally be in sight of amateur astronomers soon.

Comet C/2017 K2 (PANSTARRS), known as K2 for short, was then the most distant active comet ever spotted, a title it recently ceded to the megacomet Comet Bernardinelli-Bernstein, detected last year. But even below a superlative, K2 is notable for its activity. The comet began spewing gas and dust into the distant solar system, while it’s more typical for comets to wake up around Jupiter’s orbit much closer.
