How far, from the Earth

About 36 AU. To cross it:

  • Light4 hours 59 minutes
  • Voyager 1's speed10.1 years
  • Driving at 100 km/h6,140 years

Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.

Where this comes from

  • Moons: JPL Planetary Satellite Mean Elements and Physical Parameters, paced to JPL Horizons. NASA/JPL-Caltech. Sizes JPL leaves out are estimates, mostly from brightness: Scott Sheppard's moon pages at Carnegie.
