How far, from the Earth

About 50.6 AU. To cross it:

  • Light7 hours 1 minute
  • Voyager 1's speed14.2 years
  • Driving at 100 km/h8,630 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.
  • The orbit here is JPL Horizons' at one moment; its long-term period is about 18.28 days (Ragozzine & Brown 2009), and Hi'iaka's pull changes it.

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.
