Astronomers have measured the mass and distance of a rogue planet, finding it has a mass similar to Saturn and was ejected after a planetary breakup.

This was achieved by observing the planet simultaneously from Earth and space, a rare method that allows precise measurements.

The discovery helps explain how planets can be expelled from their systems and drift through interstellar space.

Although only a few free-floating planets are known, more are expected to be found, especially with the NASA Roman Space Telescope launching in 2027, Sci-Tech Daily has reported.

Such combined observations could improve future missions and our understanding of planet formation across the galaxy.
