What is the smallest known star?


Stars are scattered throughout outer space and vary in size, brightness, age, and color. A star is a ball of gas that is contained by its own gravity. Colors of stars vary based on their temperature. Smaller stars are called dwarfs, while larger stars are called giants.

Answer and Explanation: 1

The smallest known star is called EBLM J0555-57Ab. It was discovered in July 2017 and is approximately 600 light-years away from Earth. It is a little larger than the planet Saturn and has a gravitational pull that is 300 times more than Earth's.

EBLM J0555-57Ab was discovered while astronomers were trying to find exoplanets, which are additional planets located far away in space that orbit around a star not located in our solar system. This newly-identified small star is 2,000 to 3,000 times dimmer than our Sun and has 85 times the mass of Jupiter.
