The 85-mile-wide Bernardinelli-Bernstein comet is winging its way toward the interior of the solar system.

The Bernardinelli-Bernstein comet, identified in 2021, is officially the biggest comet ever observed.

The new record, reported on the preprint website arXiv and now accepted for publication in the journal Astronomy and Astrophysics Letters, bumps the Hale-Bopp comet from the top spot.

Hale-Bopp was discovered in 1995 and became visible to the naked eye in 1996; it was about 46 miles (74 kilometers) across.

Comet Bernardinelli-Bernstein, also known as comet 2014 UN271, has now been calculated to be about 85 miles (137 km) across.
