Astronomers with Las Cumbres Observatory have captured a new image of the recently-discovered giant comet C/2014 UN271 (Bernardinelli-Bernstein).

Comet Bernardinelli-Bernstein is named after two University of Pennsylvania astronomers, Pedro Bernardinelli and Professor Gary Bernstein, who spotted it in archival images from the Dark Energy Survey.

Also known as C/2014 UN271, the comet is estimated to be between 100 and 200 km across, or about 10 times the diameter of most solar system comets.

Comet Bernardinelli-Bernstein is not expected to become naked-eye bright: it will remain a telescopic object because its closest distance to the Sun will still be beyond Saturn. It will reach its closest approach to the Sun in January 2031.

Comet Bernardinelli-Bernstein (precisely in the center) 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.
