How far, from the Earth
1.49 million km. To cross it:
- Light4.98 seconds
- Voyager 1's speed1.02 days
- Driving at 100 km/h20.4 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 497 km on the dates it was checked against (median 44 km); between those dates as much as about 1,500 km. Dates after the data was fetched are Horizons' predictions, which it revises as a mission flies.
