The Bernardinelli-Bernstein comet is an estimated to be 60-120 miles across, 1,000 times larger than a traditional comet, astronomers said when its discovery was first announced in June. It is arguably the largest comet discovered in modern times, scientists said
Don't think for a second it's not a threat. It will affect our gravity and the gravity of other bodies in the solar system.
Scientists said that the comet could be the largest object from the Oort Cloud ever detected, and it is the first comet on an incoming path to be detected so far away.
