How far, from the Earth

1.38 million km. To cross it:

  • Light4.6 seconds
  • Voyager 1's speed23 hours
  • Driving at 100 km/h18.9 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 Earth: worst miss 2,500 km on the dates it was checked against (median 37 km); between those dates as much as about 7,400 km. Dates after the data was fetched are Horizons' predictions, which it revises as a mission flies.
