About 18.5 AU. To cross it:

  • Light2 hours 34 minutes
  • Voyager 1's speed5.19 years
  • Driving at 100 km/h3,150 years

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

Facts

  • Its size is not well measured.

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.
