NASA Confirms: Gigantic Inbound Comet is Biggest Ever Recorded

This illustration shows the distant Comet Bernardinelli-Bernstein as it might look in the outer Solar System. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It is the most distant comet to be discovered on its incoming path.

The giant comet NASA detected last year is even larger than we thought. It's got some fascinating things to tell us about Oort cloud formation.
