Megacomet C/2014 UN271 is likely BIGGER than one of Mars' moons, sporting a diameter of 93 miles wide, new study says

The megacomet first discovered in June has astronomers marveling at its size, as it may have a diameter of 93 miles, making it larger than one of Mars' moons, a new study says.

As astronomers have continued to study comet C/2014 UN271, its size has been refined, the study's authors wrote in the paper.

At a diameter of 93 miles, it would be larger than Mars' moon Phobos, the asteroid 55 Pandora and the space rock known as Arrokoth, according to an analysis from astronomer Will Grater.
