Scientists have found a vast?planet, so large that it should not exist.
The planet appears too big for its?sun and, therefore, calls into question our understanding of how planets and solar systems form, according to the researchers who found it.
The planet is more than 13 times as massive as?Earth. It orbits around a?nine times less massive star than our Sun. As such, the ratio between the two of them is 100 times higher than it is between the Earth and our sun. It is the first time a planet with such a high mass has been seen orbiting a star with such a low mass. And the discrepancy is so large that scientists thought such a planet could not exist. “This discovery drives home the point of just how little we know about the universe,” said Suvrath Mahadevan from Penn State. “We wouldn’t expect a planet this heavy around such a low-mass star to exist.”
When stars are formed out of giant clouds of gas and dust, that material sticks with the star as a disc that orbits around it. Planets can then start of that extra material and go on to make a planetary system like our own.
But science would suggest that the disc around the star in the new paper, known as “The planet-forming disc around the low-mass star LHS 3154 is not expected to have enough solid mass to make this planet,” Mahadevan said. “But it’s out there, so now we need to reexamine our understanding of how planets and stars form.” LHS 3154, would not have enough material to make a planet so large.
