How far, from the Sun

17 light-years. To cross it:

  • Light17 years
  • Voyager 1's speed302,000 years
  • Driving at 100 km/h183 million years

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

Facts

  • Spectral type T6 (SIMBAD).
  • Its distance comes from a Gaia parallax: the tiny yearly shift in its position as the Earth circles the Sun.
