Astronomers Identify Potential Fastest-Moving Exoplanet System

A star and orbiting planet in the Milky Way's galactic bulge may set a new record for speed, traveling over 1.2 million miles per hour.

Scientists have discovered a star-planet system moving at an estimated 1.2 million miles per hour, nearly twice the speed of our solar system's movement through the galaxy.
The system consists of a low-mass star and a super-Neptune planet, located about 24,000 light-years away in the densely packed galactic bulge of the Milky Way.
The discovery was made using microlensing, which detects light signals caused by the warping of space-time by massive objects, and confirmed with data from the Keck Observatory and ESA's Gaia satellite.
Researchers are working to confirm whether the system is bound together or if it represents a rogue planet and moon, with further observations planned for the coming year.
NASA's upcoming Nancy Grace Roman Space Telescope is expected to provide more insights into such high-velocity systems and their prevalence in the galaxy.
