How far, from the Earth

403,000 km. To cross it:

  • Light1.35 seconds
  • Voyager 1's speed6 hours 39 minutes
  • Driving at 100 km/h5.52 months

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 Moon: worst miss 80 km on the dates it was checked against (median 4 km); between those dates as much as about 239 km. Dates after the data was fetched are Horizons' predictions, which it revises as a mission flies.

Where this comes from

  • NASA/GSFC
  • Spacecraft trajectories: JPL Horizons, NASA/JPL-Caltech; each mission's agency credited on its card.
  • 3D model: Lunar Reconnaissance Orbiter model: NASA/Brian E. Kumanchik, NASA/Christian A. Lopez, NASA 3D Resources
