How far, from the Sun

10.5 light-years. To cross it:

  • Light10.5 years
  • Voyager 1's speed187,000 years
  • Driving at 100 km/h113 million years

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

Facts

  • It is younger than the Sun, at about 200 to 800 million years.
  • A giant planet about two-thirds to three-quarters of Jupiter's mass orbits it every 7.4 years.
  • It was a target of Project Ozma, Frank Drake's 1960 search for alien radio signals.

Where this comes from

  • Gaia DR3 parallax 310.5773 ± 0.1355 mas, Gaia DR3 5164707970261890560 (Gaia Collaboration 2023, A&A 674, A1)
