Astronomers measure the mass of a rogue planet drifting through the galaxy

Scientists have discovered a rogue planet roaming the Milky Way after combining observations from Earth and a space telescope. This rare dual perspective allowed them to weigh the planet and pinpoint where it lies in the galaxy. With a mass similar to Saturn, the planet likely formed around a star before being thrown out. The finding opens a new window into how planets are lost to interstellar space.
