With a diameter of between 100 and 200 kilometers, it is the largest comet ever found and the most distant customer identified thus far.
At the starting of 2013, the Darkish Vitality Survey (DES) mission whose mission is to review darkish power first detected an object by no means seen earlier than at the limits of the Solar System. Hypothesis about its nature continued till 2014, when an evaluation of 80,000 photographs by Pedro Bernardinelli and Gary Bernstein – an astronomer and astrophysicist at the College of Pennsylvania, respectively – started to acquire extra details about what regarded like a unpublished huge comet for science.
eight years later, scientists confirmed that the object possessed a eat, that is, a cloud of mud and fuel round it and due to this fact, at the finish of June 2021 it was formally listed as a giant kite approaching the inside of the Solar System.

C / 2014 UN271: the largest customer ever found
C / 2014 UN271 is not solely the most huge comet in historical past; he is additionally the farthest customer to our cosmic neighborhood identified up to now. Its elongated orbit expands to the oort cloud, a area situated at the edge of the Solar System with billions of objects from which the overwhelming majority of long-period comets come, which take 1000’s of years to finish an orbit.
On this case, comet C / 2014 UN271 takes about three million years to finish a interval. Therefore its latest discovery is a novel coincidence on a cosmic scale: this is probably the solely time our species is in a position to observe its passage via the Solar System.
At present, this giant of ice, rocks and cosmic mud the comet C / 2014 UN271 (Bernardinelli-Bernstein) lies between the orbit of Uranus and Neptune 20 AU from Earth, that is, twenty instances the distance between our planet and the Sun.
The comet has a perpendicular orbit with respect to the aircraft of the Solar System, so that it appears to ‘enter’ the gaseous worlds, as proven on this animation from NASA’s JPL Small-Physique Database, the place its trajectory seems with grey stripes :
Comet C / 2014 UN271’s lengthy path will attain the perihelion (its closest level to the Sun) in 2031 when it enters 11 AU, a distance much like the orbit of Saturn in our cosmic neighborhood. At that time, will probably be seen even from our planet with a mid-range telescope for a number of nights, earlier than it begins a brand new path in the direction of the oort cloud that will final for hundreds of thousands of years.
