Scientists have revealed that Comet I / Borisov, which passed near the sun in 2019, is one of the most primitive comets ever, and new observations using the Very Large Telescope (VLT) of the European Southern Observatory in Chile indicate that the comet did not pass close enough. From which star to influence its original state, so it remained pure.

According to the British newspaper “Daily Mail”, comets, which are cosmic snowballs of frozen gases, rocks and dust, can be changed by heat and radiation from stars such as our sun.

But the fact that it did not pass near a star made it in the form of the cloud of gas and dust that originally formed the comet, as I / Borisov was discovered by astronomer Gennady Borisov with a telescope on August 3, 2019 and confirmed that it came from outside the solar system a few weeks later.

Comets orbit the sun in a very elliptical orbit, which means they are not completely circular, and they can spend hundreds and thousands of years in the depths of the Solar System before returning for their closest approach to the Sun.

ESO scientists believe that 2I / Borisov never passed near any star before it took its closest approach to the sun at just over two astronomical units (AU) near the sun on December 8, 2019.

2I / Borisov survived its closest approach to the Sun, but not without partial disintegration, as astronomers revealed last year.

It was assumed that the comet was shattered when it reached this close proximity, but astronomers said that only part of it broke apart and the bulk of the comet survived unscathed, and the European Space Agency now says that 2I / Borisov “may be the most primitive and pure of all comets. “.
