The most recent discovery, from earlier this month, is 2MASS J1119–1137. In a press release, scientists called it one of the youngest and brightest "free-floating, planet-like objects" close to the sun. The research team found out that the planet is moving in sync with a young group of stars that is about 10 million years old, a group known as the TW Hydrae Association. This makes the newly found planet only half the age of a brighter lone object known as PSO J318.5−22, discovered in 2013.

"Discovering free-floating planet analogs like 2MASS J1119–1137 and PSO J318.5−22 offers a great opportunity to study the nature of giant planets outside the Solar System," lead author Kendra Kellogg, a graduate physics and astronomy student at Western University in Canada,
in a press release
. She added that these objects are “much easier to scrutinize than planets orbiting around other stars. Objects like 2MASS J1119–1137 are drifting in space all alone and our observations are not overwhelmed by the brightness of a host star next door.”
