How far, from the Sun

About 1,120 light-years. To cross it:

  • Light1,120 years
  • Voyager 1's speed19.8 million years
  • Driving at 100 km/h12.1 billion years

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

Facts

  • Wolf–Rayet stars are massive stars casting off their outer layers, which leaves most of them short of hydrogen.
  • Its distance comes from a parallax measured by the Hipparcos satellite: the tiny yearly shift in its position as the Earth circles the Sun.

Where this comes from

  • Hipparcos parallax 2.92 ± 0.3 mas (van Leeuwen 2007, A&A 474, 653)
  • This research has made use of the SIMBAD database, CDS, Strasbourg, France (Wenger et al. 2000, A&AS 143, 9).
  • This research has made use of the VizieR catalogue access tool, CDS, Strasbourg, France (DOI: 10.26093/cds/vizier).
