How far, from the Sun

17.1 light-years. To cross it:

  • Light17.1 years
  • Voyager 1's speed305,000 years
  • Driving at 100 km/h185 million years

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

Facts

  • A 2019 Gaia-based calculation has Voyager 1 passing within about 1.9 light-years of it in about 44,000 years; NASA's figures are 1.6 to 1.7 light-years in about 38,000 to 40,000 years.
  • Spectral type M4.0V (SIMBAD).
