Astronomers detect a “huge comet” in our direction; The biggest ever

two Astronomy scientists The existence of perhaps the largest comet ever seen, was discovered in June 2021. Even the body has been debated whether it could actually be planet Dwarf and still in a comet-like orbit. Moreover, the “huge comet” is on the path of the outer solar system.

The element C/2014 is called UN271 (Bernardinelli-Bernstein) and is part of the 461 objects identified as unknown. With this, an acceptable article related to Astrophysical Journal Letters Uncover many curiosities – yet unknown – around the world.

So much so that even at its closest approach in 2031, UN271 will be far from Saturn, at about 11 AU (that is, one AU equals the distance from the Earth to the Sun). This prevents the possibility of taking a closer look at something

The orbit has already been traced and its recent approach to Sol That was about 3.5 million years ago. That’s when he’s only got 18 AU, which is nearly twice the distance he’ll be this time around, just about the distance of Uranus. In addition, it is likely the closest comet ever to the Sun, so it will be the most primitive comet of all.

The researchers estimated a diameter of 150 kilometers (100 mi), which would give a size much larger than a typical comet, plus it’s at least 10 times larger than a giant comet like Hell-Bopp.

There were also hopes for more clarity about the size of UN 271 When it passed in front of a star seen from the east AustraliaHowever, the cloud covered the entire area and no matter how large the comet was, it would not be visible to the naked eye when approaching it.

Moreover, one of the first questions astronomers asked was whether a comet actually exhibits cometary activity, that is, causes matter to turn into gas and the formation of a coma. This is because UN271 was photographed in 2018 and found differences in measurements. .

Some astronomers are still eager to send a mission to UN271, with calculations that the best time for the bridge would be in 2033 and would require launch by 2028.
