Free-floating planet drifting through space tracked by scientists

Scientists have tracked a free-floating planet drifting through space, determining its mass and direction using a combination of Earth-based telescopes and a space observatory. The planet, approximately the mass of Saturn and 10,000 light years away, likely formed in a protoplanetary disc and was ejected from its region of origin. This discovery could change with the launch of NASA's Nancy Grace Roman Space Telescope in 2027.
