A huge comet will fly past Earth in July and you may want to see it

A comet first discovered in the distance in 2017 may finally soon be visible to amateur astronomers.

Comet C / 2017 K2 (PANSTARRS), called K2 for short, was then the most distant active comet ever seen, a title it recently handed over to the mega comet Comet Bernardinelli-Bernstein, discovered last year. But even down a superlative, K2 is remarkable for activity. The comet began to spew gas and dust into the outer solar system, whereas it is more typical for comets to wake up around Jupiter’s orbit, much closer.
