Hubble Confirms Largest Comet Nucleus Ever Seen

The video discusses the discovery of the largest icy comet nucleus, which is about 80 miles in diameter and has a mass 100,000 times greater than typical comets. The challenge was to distinguish the solid nucleus from the surrounding dusty coma. Hubble's observations and computer modeling helped estimate the nucleus's size. The comet is moving at 22,000 miles per hour but will remain a safe distance from the sun, beyond Saturn's orbit.
