Megacomet C/2014 UN271 is likely BIGGER than one of Mars' moons, sporting a diameter of 93 miles wide, new study says
Megacomet C/2014 UN271 could have a diameter of 93 miles, a new study says It had previously been thought to be 1,000 times the size of a normal comet Earlier this month, astronomers spotted an 'apparent outburst' of brightness on the comet, but it has since faded Comet 2014 UN271 is currently about 19 astronomical units (AU) from the sun In July, astronomers in New Zealand spotted the first activity on the megacomet It originated from the Oort cloud, a region thought to surround the solar system By Chris Ciaccia For Dailymail.Com

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.
