Most comet nuclei measure a few miles across, but C/2014 UN271 has them all beat, with a nucleus that’s 50 times larger than the ones normally found in most known comets.

The comet, known as C/2014 UN271 (Bernardinelli-Bernstein), has an estimated diameter of about 80 miles. That's bigger than Rhode Island and about 50 times larger than the heart of most comets.

The cold behemoth is called C/2014 UN271 or comet Bernardinelli-Bernstein. It was discovered in 2010 by astronomers Pedro Bernardinelli and Gary Bernstein.

The comet is hurtling toward the inner solar system at 22,000 miles per hour, NASA said. The comet, named Comet C/2014 UN271, has the largest nucleus ever seen, according to NASA.
