It was announced that the largest comet ever discovered in space was imaged for the first time in 2014, and the size of its core is only 128 km. Moreover, it is rapidly approaching the Earth.
There are many stars, comets, planets and exoplanets that we see and cannot see in the sky. Research by astronomers reveals results that will surprise us more and more every day. NASA’s Hubble Space Telescope With the help of a very interesting comet was discovered.
What distinguishes this comet from the others, so far largest comet discovered It happened, and in fact, this discovery was not the first time. Let’s take a look at the details of this comet, which will astonish researchers, and how it was discovered.
It will be at its closest distance to Earth in 2031
The comet, named Comet Bernardinelli-Bernstein (C/2014 UN271), first imaged in 2014, was more than 3 billion miles from the Sun when it was first imaged. This made it very difficult to investigate. Although astronomers estimate the size of this comet to be quite large, this has not been proven until now. With images from the Hubble Telescope on January 8 allowed to calculate the core size of the comet.
Man-To Hu from Macau University of Science and Technology in Taipa and his team modeled it on a computer with images obtained from the telescope. Modeling, which took into account its distance and telescopic view, showed that the comet had a nucleus of unprecedented size. As a result of the examinations, the comet’s approximate It has a core of 128 km in size and weighs about 500 trillion tons. appeared. However, this gigantic comet Traveling at 22,000 miles and approaching Earth observed. According to calculations made by researchers, it will be at its closest distance to Earth in 2031. That means it will be about 1 billion miles from the Sun. It is currently about 2 billion miles from the Sun.

Just about the same size as the largest comet ever discovered, just by the size of its inner core, Comet Bernardinelli-Bernstein is even more massive when the coma and light filtering surrounding its core are taken into account. Researchers believe this new discovery pertaining to comets from the Oort Cloud Hope you can give details.
