Researchers have discovered a star designated S301 that represents a significant find in astronomical observation. The star travels at roughly 25,000 kilometers per second around Sagittarius A*, the supermassive black hole located at the center of the Milky Way galaxy. This velocity is approximately 100,000 times faster than commercial aircraft speeds.
What distinguishes S301 is its extraordinarily close proximity to Sagittarius A* combined with its rapid orbital motion. The star completes one full orbit in just 8.7 years while maintaining an average distance from the black hole roughly equivalent to the distance between Earth and the Sun multiplied by 12. This represents an unprecedented configuration for stellar observation near a supermassive black hole.
Scientists believe S301 offers a unique opportunity to test fundamental physics. According to Einstein’s general theory of relativity, rotating black holes warp the spacetime around them, affecting the orbits of nearby celestial objects. The star’s tight, highly eccentric orbit may allow researchers to directly measure the spin of Sagittarius A* for the first time, something previously thought to require decades of observations from multiple stars.
The discovery was made using the European Southern Observatory’s Very Large Telescope Interferometer at Paranal Observatory in Chile, which combines light from four 8-meter telescopes. Scientists have traced S301’s orbital path back to 2017 and plan to track it through its next closest approach in 2031, expecting to gather sufficient data to calculate the black hole’s spin within the next 10 years.
Researchers note that despite its extreme proximity to Sagittarius A*, S301 will not cross the black hole’s event horizon and will remain on its current orbital path. Such a measurement would provide critical validation of Einstein’s theory and enhance understanding of how supermassive black holes have shaped the evolution of the Milky Way.
