Scientists using a telescope in Chile have found the fastest star known in the Milky Way galaxy. This star moves very quickly around the supermassive black hole at the center of our galaxy and takes less than 9 years to orbit it.

Key Facts

  • The star travels at about 15,534 miles per second (25,000 kilometers per second).
  • It orbits the Milky Way’s central black hole faster and closer than any previously known star.
  • The star completes one orbit in just 8.7 years.
  • The discovery was made using the European Southern Observatory’s Very Large Telescope in Chile.
  • Scientists study stars near black holes to learn about the black holes’ properties, like how fast they spin.
  • The star is 10 times closer to the black hole than the earlier closest known star.
  • Many more such fast stars might still be found with advancing telescope technology.
  • Findings about this star were published in the journal Nature.
