Rogue Planet Found 10,000 Light-Years Away, Wandering Sunless in Cosmic Darkness

• Scientists discovered a rogue planet 10,000 light-years from Earth, wandering without a sun.
• The planet's mass is one-fifth that of Jupiter, making it the first such rogue planet with accurately measured distance and mass.
• It was likely ejected from its original system due to gravitational interactions, a process called 'Gravitational Billiards'.
• Discovered using gravitational microlensing, observed by telescopes in Chile, Australia, and the Gaia Space Telescope on May 3, 2024.
• NASA's upcoming Nancy Grace Roman Space Telescope (2027) is expected to find thousands more rogue planets, enhancing our understanding of planet formation.
