How far, from the Sun

About 27,000 light-years. To cross it:

  • Light27,000 years
  • Voyager 1's speed480 million years
  • Driving at 100 km/h291 billion years

Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.

Facts

  • It holds the Pistol Star, one of the most luminous stars known.
  • Dust hides it from visible light, so it has no parallax of its own; it is placed at the Galactic Centre's distance.

Where this comes from

  • Placed at the Galactic Centre's distance, GRAVITY Collaboration 2022, A&A 657, L12 (8,277 ± 9 pc), the value used for Sagittarius A*; it lies within about 100 light-years of it on the sky
