The gravity of a black hole is so powerful that even light can not escape their clutches – hence the name 'black hole'.
The runaway star, S5-HVS1, is
The black hole, known as Sagittarius A * is thought to pull in stars, gas clouds and planets, devouring them with their huge gravity.

The scientists, whose paper is on the preprint server Arxiv speculate that it has a binary system interacting with Sagittarius A *.
The paper is called 'The Great Escape: Discovery of a nearby 1700 km / s star ejected from the Milky Way by Sgr A * '.
Supermassive black holes are common in the centers of galaxies and may generate the most energetic phenomena in the known universe.
The researchers write 'When integrated backwards in time, the orbit of the star points unambiguously to the Galactic Center, implying that S5-HVS1 was kicked away from Sgr A * with a velocity of ~ 1800 km / s.
' The ejection trajectory and transit time of S5-HVS1 coincidence with the orbital plane and age of the annular disk at the Galactic center, and thus may be linked to its formation.
'With the S5-HVS1 ejection velocity being almost twice the velocity of other hyper-veloc ity stars previously associated with the Galactic Center, it has been said to be the same mechanism or the same. "
