How far, from the Sun

About 6,310 light-years. To cross it:

  • Light6,310 years
  • Voyager 1's speed112 million years
  • Driving at 100 km/h68.1 billion years

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

Facts

  • A 2013 study put its radius at about 1,700 times the Sun's, though its uncertain distance makes that uncertain.
  • It is a pulsating variable that changes in brightness over about two years.
