A newly found star circles the Milky Way's central black hole every 8.7 years and passes it at about 25,000 kilometres a second, more than 8 percent of the speed of light, and the pass is so close that its discoverers say there is a fair chance of measuring the hole's spin within a decade
S301 turned up as a smudge in a reconstructed image in 2023 and was then found again in archived pointings from 2021 and 2017. No spin has been measured. The decade-long timeline comes from a simulated dataset running to 2035, one assuming a radial velocity this star has never yielded and an astrometric precision the authors describe as the expected final performance of their upgraded instrument.

Astronomers detect fastest known star in Milky Way
Astronomers have identified S301, the fastest known star in the Milky Way, orbiting the galaxy's central supermassive black hole at approximately 25,000 km per second. The post Astronomers detect fastest known star in Milky Way appeared first on RocketNews.
Astronomers may have found new evidence that 'black hole stars' really exist. This is a new, as yet unconfirmed, type of celestial body: gigantic spheres of gas that look like a star from the outside, but which hide a black hole inside. A black hole star has reportedly been found that emits 100 billion times more energy than an ordinary star and is as large as our entire solar system.
A star moving at high speed could test the rotation of the black hole at the center of the Milky Way
The fastest star in the Milky Way reaches 25,000 km/s and could reveal how the central black hole spins.A newly discovered star, S301, could help astronomers determine the spin of Sagittarius A*, the black hole at the center of the Milky Way, for the first time.Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, has a spin that has yet to be precisely determined. A black hole's rotation, or spin, is described by …
From the pristine skies of the Atacama desert, astronomers discovered the star S301. Turning to the edge of the black hole Sagittarius A*, this object reaches extreme speeds that defy known physics and test the theory of relativity.Our star S301, today orbits around a black hole where it reaches unimaginable speeds.In the exact center of our galaxy, more than 26,000 light years from Earth, lives Sagittarius A* (Sgr A*), a supermassive black hole…
The star, named S301, approaches the black hole Sagittarius A* at a distance The entrance While our Sun travels at more than 800 thousand kilometers per hour, this newly discovered star moves at 25 thousand kilometers per second in the center of the Milky Way was first published in Research and Development.
