Bernardinelli-Bernstein has a diameter of more than one hundred kilometers and travels three million a year.
US astronomers have found a comet 10 times larger than average in the Oort cloud, according to the Dark Energy Survey. According to AC / 2014 UN271, or its discoverers, the diameter of Comet Bernardinelli-Bernstein is estimated to be between 100 and 370 km, and on January 23, 2031, after Saturn, it will reach the point of its orbit almost perpendicular to the Solar System closest to the Sun.
The orbit of a celestial body the size of an asteroid is very long, revolving around the sun more than three million years ago. In images taken after 2014, it did not even appear to be anything other than an asteroid among the many, and it was not until 2018 that it began to form a plume under the influence of solar radiation, officially receiving the designation of a comet.
The orb was discovered by University of Pennsylvania employees Pedro Bernardinelli and Gary Bernstein on footage of the 570-megapixel Dark Energy Camera (DECam) installed at the CTIO Observatory in Chile.

The main task of the device, created by the US Department of Energy at Fermilab, was to map 300 million galaxies between 2013 and 2019, but it also identified several icy celestial bodies orbiting Neptune. Based on about eighty thousand photographs, Bernardinelli and Bernstein identified 800 Transneptunian celestial bodies, 32 of which showed C/2014 UN271.
Experts could not predict how amazing the giant cauldron will be, but the Vera C. Rubin Observatory, which is part of the NOIRLab program, will follow suit.
