A comet is approaching Earth to tell us the secrets of our solar system

Comet "Bernardinelli-Bernstein" a "time machine" that carries unprecedented information about how the solar system originated and evolved.

Chance to discover new secrets

Pennsylvania (United States) rushes the largest comet ever discovered is located towards the ground, what will give astronomers an insight is invaluable for the solar system.

Comet “Bernardinelli-Bernstein” was first discovered seven years ago, and it is believed to be 120 miles (200 km) wide, nearly 12 times the size of Mount Everest, according to what The Sun newspaper reported.

The impressive comet was spotted by University of Pennsylvania astronomers Pedro Bernardinelli and Gary Bernstein last month, and the duo published a paper explaining everything they knew about the space object based on seven years of data collection and a series of observations over the summer.

Scientists have described the comet as a "time machine" that holds unprecedented information about how the solar system originated and evolved.

"The story behind the comet will tell us what was in the solar system billions of years ago," Bernardinelli told The Daily Beast. We can use that to understand the things we see today in other parts of the solar system.”

What makes this comet unique is that its chemical composition has not changed fundamentally since its formation due to its size and distance from the sun.

"Not much has happened to this body since it was formed in the early days of the solar system," Bernardinelli explained. We can consider it a window into the past.” Bernardinelli and Bernstein share their findings in a paper that has been submitted to the Astrophysical Journal Letter.

The comet is believed to be between 60 and 120 miles across, making it the largest comet ever seen by humans. Bernardinelli-Bernstein is expected to reach our inner solar system in 2031, when it oscillates between Uranus and Saturn. The comet is so large that it was confused with a dwarf planet, before scientists discovered its glowing tail.

While the comet is expected to reach the inner solar system within about a decade, astronomers say that it poses no threat to Earth, and is currently 29 astronomical units away from us, about 29 times the distance between our planet and the sun.

And when it gets close to it sometime in 2031, you'll need a telescope to spot it.And for space enthusiasts eager to see a comet soon, another comet is expected to pass close to Earth.
