In a recent study, researchers from the International Dark Energy Survey Project, or Dark Energy Survey, discovered new data on comet Bernardinelli-Bernstein.

This star, officially called object C / 2014 UN271, has a diameter of up to 150 km, or about seven times the diameter of Phobos. satellites of mars.

Through successive studies, the size of this object was refined, until it was determined that its mass exceeded that of Comet Hale-Bopp, known as the Great Comet of 1997.

According to calculations by astronomer Will Graeter, C / 2014 UN271 will not only be larger than the satellite on Mars, but it will also overtake asteroid 55 Pandora and a space rock known as Arokoth, he explains. he. Study published on the arXiv portal.

Reading this morning’s tweet Dr Pedro Bernardinelli, I was trying to understand the size of comet Bernardinelli-Bernstein (C / 2014 UN271). Here is a graph I made to show its size in relation to other objects in the solar system.

The giant comet, which was discovered in 2014 and is heading towards our solar system, apparently comes from the toe nuvem – an imaginary region that surrounds the ends of the solar system and contains billions of comet-like objects. Although there are no direct observations to confirm its existence, several circumstantial factors indicate its existence.

Initially, C / 2014 UN271 was mistaken for a dwarf planet, but then showed signs of activity and was reclassified as a comet.

Astronomers have calculated that on its closest passage through our planetary system, which will occur in 2031, the mysterious object will reach about 10.9 AU from the Sun when it hits the Sun. orbit of Saturn. An astronomical unit (AU) is the distance between the Earth and the Sun.
