6,830 km. To cross it:
- Light0.0228 seconds
- Voyager 1's speed6 minutes 45 seconds
- Driving at 100 km/h2.84 days
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 65 km on the dates it was checked against (median 48 km); between those dates as much as about 196 km. Dates after the data was fetched are Horizons' predictions, which it revises as a mission flies. This date is about 4 days past the Horizons answer it comes from (2026-11-12), and a low orbit's forecast moves with drag and reboosts: allow about 207 km (2° round its orbit), and more if it has been reboosted.
