How far, from the Sun

About 16,900 light-years. To cross it:

  • Light16,900 years
  • Voyager 1's speed301 million years
  • Driving at 100 km/h183 billion years

Facts

  • It is one of the brightest stars in the Milky Way, shining like about a million Suns.
  • Its distance comes from a Gaia parallax: the tiny yearly shift in its position as the Earth circles the Sun.
