Newly discovered Earth-like rogue planet might be the smallest free-floating world

Researchers have found a world, which is similar in size to Earth, travelling alone without any family. This could be the smallest rogue world ever detected.

Experts use light coming from a star to detect the various exoplanets. So, it is very difficult to spot a world without a star. To hunt the world, scientists used "gravitational microlensing," which involves watching foreground objects pass in front of distant background stars.
