Astronomers detect fastest known star in Milky Way

WASHINGTON: Scientists have detected the fastest-known star, a stellar speedster that’s zooming across the supermassive black gap residing on the heart of our galaxy and would possibly maintain the important thing to measuring the spin of this celestial beast for the primary time.

The star, round 50% extra huge and 5 instances brighter than our solar, travels at speeds as much as about 56 million miles (90 million km) per hour because it orbits the Milky Means’s central black gap — named Sagittarius A*, or Sgr A*. That’s greater than 8% the pace of sunshine. No different star in our galaxy or elsewhere has ever been clocked at that pace.

The star, named S301, is touring in a extremely elliptical path round Sgr A, taking about 8.7 years to finish an orbit. Its closest strategy to the black gap is about 11.5 instances Earth’s orbital distance from the solar, a metric referred to as an astronomical unit.
