For an object traveling all the way from another solar system to ours, it requires a lot of time and cosmic effort. The nearest solar system to our own is at a staggering distance: around 4 light-years. While it may sound like nothing at an astronomical scale, it’s really an unimaginable distance for the human mind. With the current technology, we could never arrive there.
Yet another interstellar visitor has been found out to travel a huge distance to the planets of our own solar system. The comet 2l/Borisov has been spotted recently into what is believed to be the best image possible.
2l/Borisov is much bigger than Earth
The W.M. Keck Observatory’s Low-Resolution Imaging Spectrometer has been used by astronomers at Yale University from Hawaii, and that’s how they have been able to capture the best look at the interstellar comet.
Pieter van Dokkum, a Yale astronomer, stated:
It’s humbling to realize how small Earth is next to this visitor from another solar system
Therefore, the 2l/Borisov comet is around 14 times bigger than our planet, which is pretty impressive for a comet.
On December 8 the comet passes closest to Earth
Astronomers seem to have another big chance to explore the comet as much as they can, when the celestial object will pass very close to Earth on December 8: within only 190 million miles.
Gregory Laughlin, an astronomer at Yale, stated:
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,
Although it’s pretty rare to see an interstellar visitor coming near our planet, such discovery is not really entirely new. Oumuamua has been spotted back in 2017, which is also a comet.
Who knows what other further insights can interstellar objects provide for our astronomers. Panspermia is one of the scientific theories regarding the emergence of life on Earth, which claims that the first amino-acids were brought to our planet by comets and asteroids.
