PASADINA, Calif. - The largest comet in human history has been orbiting our sun for nearly a million years. This mysterious object has been called the greatest astronomical crime of our solar system.
The comet, seen from the Hubble Space Telescope, is named C / 2014 UN271 and its nucleus is by far the widest in our routine. The 140 km long center is 50 times larger than a normal comet. Studying it yourself will help you to understand the shape and evolution of the comet.
According to experts, the emergence of C / 2014 UN271 has also come from the advice over cloud. This is a vast expanse of cold and icy bodies from which comets come and pass around our solar system. The cloud is far away and beyond the solar system. Some astronomers even consider the over-cloud to be a hypothesis.
Whenever icy bodies come out of this place, it is pulled by the immense gravitational force of our sun and as it reaches around the sun, its molten ice becomes like a long tail. When light falls on it, we feel a long icy tail and so we call it a comet or comet.
The idea is that the formation of the over-cloud itself can be understood by looking at it. By now, we know that the cloud was formed long ago in the inner solar system. Then big gaseous planets like Saturn and Jupiter came into existence and the orbital clouds moved away from there.
"The comet is just one example, and there are probably hundreds of thousands of such comets, but they are so dim that we can't see them very well," said David Jewot, an astronomer at the University of California, Los Angeles. At first glance, it was thought to be an unusually large comet, and now it has been confirmed.
Scientists have estimated the center of the comet from clear images and computer modeling. Its orbit is also the longest and longest, while its long tail is made of ice and gas. Although C / 2014 UN271 was officially announced last year, it appeared twice in the Dark Energy Survey data in 2014 and 2018, but another study found it in 2010.
Interestingly, its orbit is very elliptical and long, and it completes one cycle in 3 million years, while it has been approaching the sun for 1 million years. In 2031, it will be closest to the Sun, but it will also be one billion kilometers.
