A massive comet the size of a small planet heading straight for our solar system

According to a recent study, a giant comet — so large that scientists initially mistook it for a dwarf planet — is speeding through space toward our solar system and will arrive in approximately ten years.

When the Bernardinelli-Bernstein comet was discovered in June, scientists assessed it 60-120 miles across, 1,000 times larger than a regular comet. According to scientists, it is arguably the enormous comet ever discovered.

The comet, on the other hand, poses no harm to the planet. It will approach closest to the sun in 2031, at a distance of 10.71 astronomical units (au), barely outside Saturn's orbit.

The comet's voyage began 40,000 au away from the sun, deep within the enigmatic Oort Cloud.

According to scientists, the comet could be the most prominent object ever identified from the Oort Cloud, and it is the first comet on an entering course to be detected so far away.

When no tail or "coma" typical of comets was spotted six years ago, astronomers began investigating the object. The presence of a tail was discovered after three years of inquiry, confirming the object's status as a comet.

Despite its proximity and size, astronomers believe that a telescope will be required to see the object. It is thought to have never been observed by humans before, predating our existence the last time it passed by, but an orbit study revealed that it would be making a significantly closer approach to the sun on this voyage.

"We have the honor of discovering perhaps the largest comet ever seen — or at least the largest well-studied one — and catching it early enough for people to watch it evolve as it approaches and warms up," said Gary Bernstein of the University of Pennsylvania, who discovered the object with colleague Pedro Bernardinelli.

"It hasn't been to our Solar System in over 3 million years."
