A Comet From Another Solar System Will Pass by Earth

A strange cosmic body is reportedly sailing towards our planet, but no one knows where it comes from and where it goes. It is the second interstellar object ever detected passing through the Solar System.

The 2I/Borisov will manage a close flyby Earth and Sun on December 7 or 8, according to a team of astronomers. The object has first been identified this summer, and it keeps drawing nearer our planet. 2I/Borisov will be at its closest to Earth, at approximately 190 million miles, in early December.

The scientists believe the comet took shape in a Solar System that’s located beyond ours and was expelled into interstellar space as a result of a close collision with a planet in its home Solar System.

The Comet is Becoming Dimmer

Yale astronomers Pieter van Dokkum, Cheng-Han Hsieh, Shany Danieli, and Gregory Laughlin were the ones that managed to capture the photograph back on November 24th, using the W.M Keck Observatory’s Low-Resolution Imaging Spectrometer located in Hawaii. The team also created an image that depicts the way the comet would look when compared to Earth.

According to van Dokkum, the comet’s rear side, which is shown in the image, is almost 100,000 miles long. This is approximately 14 times the size of Earth. The researcher said that it is humbling to realize how small our planet is in comparison to this cosmic body that comes from another Solar System.

Laughlin also said that 2I/Borisov is vanishing as it approaches Earth, expelling gas and fine dust in its tail. 

“Astronomers are taking advantage of Borisov’s visit, using telescopes such as Keck to obtain information about the building blocks of planets in systems other than our own,” he said.​

The solid core of the comet is only approximately a mile wide. As it began responding to the Sun’s warming consequences, the cosmic body has transformed into a dim comet, the scientists explained.
