Giant comet Bernardinelli-Bernstein explodes in solar system

This is the buzz of the moment, it is not a comet object Centuries In The Solar System Going towards the present சோலைல் It is called 2014 UN271. As the name suggests, it was actually discovered in 2014, but Nuspier was only aware of the discovery years later when he analyzed data that betrayed its existence. The Astronomers Point Bernardinelli and Gary Bernstein actually discovered the 2014 UN271 recently. Dark energy study (DES), which serves its main purpose Light On natureDark energy.

From cosmology to astronomy

DES has already made it possible to detect many transneptonic objects. Remember A transneptunian substance or DNO is an icy body that usually resides in us. The Solar System BeyondAround the circular path From Neptune. 2014 UN271 is a TNO that currently approaches the Sun at 20.2 astronomical units (AU) or 3 billion kilometers away. Its orbital parameters are determined, so we know that it develops from Oort cloud, And it has an elliptical orbit Perihelion It is 10.9 AU from the Sun, which is slightly out of orbit Saturn. He is expected to reach it in January 2031. His aphelia The previous one was located at 40,000 AU or 0.6 Light year, In Oort cloud, But after 10 years the closest orbit to the Sun 2014 UN271 will have to depart in the direction of another abyss 0.9 light-years away from the Sun, and then return only at 4 to the suburbs of the solar system’s planets, 5 million years old, according to astronomical calculations.

A complex diameter, less than 100 km or approximately 370 km.

On the other hand, the size of the 2014 UN271 is not yet well known to us. A comet It usually has a range of ten kilometers. But according to 2014 UN271, measurements of its brightness in 2014 suggest that its magnitude would be in the range of one hundred kilometers, perhaps more than 300 kilometers.

In the latter case, one can almost talk about a dwarf planet. However, signs of comet activity have already been detected, and in all cases we can reasonably say that 2014 UN271 was recently renamed C /2014 UN271 (Bernardinelli-Bernstein), Is the largest comet observed by modern astronomers since the beginning of their study.

The degassing The result should be more than three billion kilometers Molecules Especially turbulent like CO and CO₂. 2014 UN271 Its observation is not possible because it has the best approach to the distance between Saturn and the Sun.Eye Only naked and amateur astronomers with a 200mm telescope can notice this. It should be worth trying to do this l’eVscope.
