How far, from the Earth

6.19 AU. To cross it:

  • Light51 minutes
  • Voyager 1's speed20.9 months
  • Driving at 100 km/h1,060 years

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

Facts

  • JPL Horizons trajectory round the Sun: worst miss 794 km on the dates it was checked against (median 0 km); between those dates as much as about 2,400 km. Dates after the data was fetched are Horizons' predictions, which it revises as a mission flies.

Where this comes from

  • NASA/GSFC/SwRI
  • Spacecraft trajectories: JPL Horizons, NASA/JPL-Caltech; each mission's agency credited on its card.
