Astronomers discover high-speed star that may host a massive exoplanet

Astronomers have discovered a celestial object moving through the Milky Way at over 1.2 million mph. This object is thought to be a small star that may carry a massive exoplanet, potentially making it the fastest-known planetary system. The star, located about 24,000 light-years away, was first identified in 2011. A new study links it to this recent observation, but its exact nature and speed are still being verified. If the object's speed exceeds 1.3 million mph, it could escape the Milky Way. Researchers are monitoring its movement to confirm its identity and trajectory, considering alternative theories about its nature.
