How far, from the Earth

1.31 AU. To cross it:

  • Light11 minutes
  • Voyager 1's speed4.41 months
  • Driving at 100 km/h223 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 Mars: worst miss 132 km on the dates it was checked against (median 13 km); between those dates as much as about 396 km. Dates after the data was fetched are Horizons' predictions, which it revises as a mission flies.
