How far, from the Sun

1.57 million light-years. To cross it:

  • Light1.57 million years
  • Voyager 1's speed27.8 billion years
  • Driving at 100 km/h16.9 trillion years

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

Facts
