They have discovered a giant megacometer that has never been seen approaching the solar system so fast

This comet is so large that it was initially thought that it might be a smaller planet. Named 2014 UN271 or Comet Bernardinelli-Bernstein by scientists who discovered it, it is 100 to 300 kilometers long.

According to the El Pas newspaper in Spain, the object was identified on June 19 from data taken between 2014 and 2018 by Cerro Tololo’s Inter-American Laboratory in Chile, which is 20 times the average distance to Earth. Sun, but by January 2031 the split is estimated to have halved.

This comet is seen beyond entering the inner solar system for a unique visit to Uranus 600,000 years ago. It is the largest comet ever seen. However, we can be sure that the comet Bernardinelli-Bernstein will not hit Earth.

But it is also one of the largest comets ever discovered, the largest being the comet Sarabad, known as the “Great Comet of 1729”, easily visible to the naked eye.

Compared to the well-known Hale-pop, it may be the largest comet found in the solar system in modern times, becoming a sight to the naked eye in 1997 with Holly’s comet about 60 km in diameter and 10 km wide.

The comet was discovered in 2014 by UN 271 astronomers Pedro Bernardinelli and Gary Bernstein using archive data from the Dark Energy Survey (DES), an infrared and optical wavelength study aimed at exploring the dynamics of the Earth’s expansion and the dynamics of the universe and evolution. On a large scale in its structure.
