NASA has just confirmed the discovery of the largest comet ever detected and it is very, very big.
Researchers have been studying the object since November 2010, when its core was first spotted, but not sure what it was. At that time the object was as far from the Sun as Neptune.
According to what has detected the Hubble Space Telescopethe comet called C/2014 UN271 (Bernardinelli-Bernstein) comes from the Oort Cloud and has been traveling towards the Sun for more than a million years.
The huge object is 50 times larger than most known comets, at almost 140 kilometers (about 85 miles) across.
The findings could help researchers better understand how comets grow in the Oort Cloud, which is up to 5,000 times greater than the distance between the Sun and Earth, so all research on her were until today theoretical.
Oort Cloud comets are thought to have originally been flung off the edges of the solar system during the early days of the solar system, when larger planets like Jupiter and Saturn were still adjusting to their orbits.
“This comet is literally the tip of the iceberg of many thousands of comets that are too faint to see in more distant parts of the Solar System,” says UCLA astronomer David Jewitt.
Scientists expect this huge comet to reach its closest approach to the Sun, known as perihelion, in 2031.
