The giant comet coming towards the earth, the largest ever, makes one revolution in 6 lakh years
A 'supercomet' coming from the outer a part of our Solar system was believed to be a dwarf planet for its size. it'll not go very near the Sun and can pass near Saturn. Scientists are very excited to review it because its size is big and also the distance is additionally short which is rare. This comet was coming from a part of the named Oort Cloud, which is extremely important to review in itself and may also reveal many mysteries of the system.
This comet has not come to our Solar System for 3 million years. We do not know much about the outer part of the Solar System yet. Therefore, scientists are more inquisitive about the objects coming from there. The comet was discovered by University of Pennsylvania astronomer Gary Bernstein and his team. He has given more information about this within the new paper. The paper states that C/2014 UN271 (Bernardinelli-Bernstein) has not previously come closer than 18 astronomical units to the Sun.
The team has found in its analysis that it started its journey towards the sun at a distance of 40,400 AU. It comes in Oort cloud. This part goes between two thousand and one thousand thousand AU and is home to icy objects. When it was discovered it was at a distance of 29AU. it's believed that it'll be closest to the Sun in 2031 after 10 years at 10.97AU.
Its size is 155 km diameter but thanks to the gap it'll be visible only with the assistance of telescopes. Studying it's special because it's believed that these icy rocks haven't changed much since the formation of the Solar System 4.5 billion years ago. On the idea of its chemical composition, we'll also get to understand about the Early Solar System. It takes 6.12 lakh years, not some days, to finish one revolution in its orbit. within the last seven years it's been covering a distance of 1 AU each year.
Comets also revolve round the sun like asteroids but they're not rocky but made from dust and ice. When these comets move towards the sun, their ice and dirt develop into vapor, which appears like a tail to us. The special thing is that the comet visible from the Earth is truly very distant from us. At the identical time, the Oort Cloud is a vicinity where there's gas and dirt that revolves around the Solar System.
