Astronomers discover the smallest star recorded till date

A team of astronomers at the University of Cambridge claimed to have spotted the smallest star ever discovered by astronomers.

The newly-discovered star dubbed EBLM J0555-57Ab is located roughly 600 light years away. Scientists also found that it is part of a binary system. They were able to spot it as it passed in front of its larger companion.

EBLM J0555-57Ab is just a sliver larger than that of Saturn in size. Its gravitational pull at its stellar surface is nearly 300 times stronger than what human beings feel on Earth.

Lead study author Alexander Boetticher of Cambridge's Cavendish Laboratory & Institute of Astronomy said their discovery revealed how small stars could be.

Sharing the discovery, Boetticher said, “Our discovery reveals how small stars can be. Had this star formed with only a slightly lower mass, the fusion reaction of hydrogen in its core could not be sustained, and the star would instead have transformed into a brown dwarf.”

Details of the just spotted smallest star appeared in the most recent edition of the journal Astronomy & Astrophysics.
