A star orbiting the black hole of the Milky Way at 18 million miles per hour

A recently discovered star, now known as S4716, is traveling at an astonishing 5,000 miles (8,000 km) per second around the black hole

The vast expanse of our universe means astronomers are always finding something they’ve never seen before.

Earlier this week, astronomers spotted Two bus-sized asteroids heading toward Earth, which will pass a quarter of what separates us from the Moon.

S4716 is the fastest star orbiting Sgr A*. It completes its orbit around 14.6 million km (23.5 million km) in diameter.

S4716 is part of a dense group of other stars also orbiting Sgr A* that astronomers refer to as the S group.

All stars in this group move at high speeds but differ in their mass and brightness. Another star in this group, known as S2, 

S2’s orbit around the black hole takes 16 years and is closer to 11 billion miles (18 billion km) from Sgr A*
