At the center of our universe is Sagittarius A* (SGR A*), a massive black hole about four million times the mass of the sun. Because SGR A* is so large, its gravitational effects are extreme and can be detected by looking at nearby stars. Swirling around SGR A* are stars and mysterious objects locked in a cosmic
two-step box along with this giant monster. These stars, along with the mysterious objects and SGR A*, are moving at an extreme pace.
However, Scientists Have Discovered The Fastest Star Around A Massive Black Hole Travelling At 8% The Speed Of Light Through Our Milky Way! A study published in Thursday’s (August 13) ‘Astrophysics Journal’ examined the region around SGR A* to find signs of stars. Previous studies have found that numerous stars tend to orbit these supermassive black holes in highly unusual orbits. Collectively known as S stars, these stars orbit very close to the black hole.

Because these S stars orbit very close to the black hole, they are tough to detect. However, the team examined images between 2004 to 2016. To explore these images, the team used instruments mounted on the Eastern Southern Observatory’s gigantic telescope in Chile. On examination, they found five new stars in the cluster, collectively known as S4711-S4715, while tracking their movements around SGR A*.
The results add to the evidence that a significant amount of stars orbit SGR A* at distances the size of our solar system. Because of their proximity to the deep abyss at the center of the Milky Way, these stars are well aware of the extreme physical phenomena.
Fastest Star Around SGR A* Travels At 8% The Speed Of Light.
A team of astronomers at the University of Cologne, Germany, has been studying the space region around the black hole. In January 2020, they reported the observations of the star S62. Their observations said that S62 orbits the black hole every 9.9 years, making it the shortest orbital period.
However, it also makes it the fastest star to flash around the Milky Way’s black hole. However, new data from the team showed a decline in both records for the S62. According to the Galaxy’s Telegram, one of its newly discovered stars, S4711, orbits the Milky Way’s black hole every 7.6 years. This is claimed to be the shortest orbital period ever recorded.
On the other hand, another star, S4714, is extreme and isn’t at the same distance as S4711 from the SGR A*. The S4714 is reportedly traveling around the black hole at 8% the speed of light. At this speed, the star is moving at about 15,000 miles per second and can reportedly circle the Earth in 1.5 seconds. The highly eccentric orbits of S stars provide further evidence for Einstein’s theory of general relativity.
Einstein’s theory predicts how space, time, and gravity interact. Simultaneously, it also suggests that large dense objects such as black holes can distort the space around them. By studying S stars, astronomers can see some of the motions predicted by Einstein’s theory. The team believes that improved data will provide a better understanding of the space around SGR A*. Simulatensouly, the team expects to find more stars in very tight orbits shortly.
