How far, from the Earth

0.87 AU. To cross it:

  • Light7 minutes 14 seconds
  • Voyager 1's speed2.93 months
  • Driving at 100 km/h148 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, then Mercury: worst miss 323 km on the dates it was checked against (median 72 km); between those dates as much as about 969 km. Dates after the data was fetched are Horizons' predictions, which it revises as a mission flies. Its dot steps by about 1,800 km on 2026-11-21, where its path changes from round the Sun to round Mercury: Horizons has the planet in a slightly different place from astronomy-engine, whose position is added here.
