Saturn-Sized Rogue Planet Detected 10,000 Light-Years Away
Scientists have confirmed the existence of a rogue planet, a starless world, for the first time by determining its distance and mass. Using gravitational microlensing, the astronomers observed an object distorting light from a distant star, approximately 9,950 light-years from Earth, with a mass about 70 times that of Earth. This discovery, made possible by observations from multiple observatories and the Gaia space telescope, suggests that these free-floating planets are likely abundant in the Milky Way, even more numerous than the stars themselves. The newfound data will assist in understanding planet formation and how some planets become rogue, while upcoming telescopes promise to find even more of these wandering worlds.
