Millions of years to complete one round
So far, it is being considered as 100-370 km long in the assessment. Its specialty is also its class. According to the analysis, this object goes near the earth and then comes in the Oort cloud. This is the region where the gas and dust that revolves around the solar system occurs. It takes 6.12 lakh years, not a few days, to complete one revolution in its orbit.
Right now it is at a distance of 22 astronomical units from the Sun. It is 22 times the distance of the Sun from Earth. However, in the last seven years, it has been covering the distance of one AU every year.
What are comets?
Mega-comet also revolves around the sun like asteroids but they are not rocky but made up of dust and ice. When these comets move towards the sun, their ice and dust turn into vapor, which looks like a tail to us. The special thing is that the comet visible from the earth is actually very far away from us.
