How far, from the Sun

15.2 light-years. To cross it:

  • Light15.2 years
  • Voyager 1's speed270,000 years
  • Driving at 100 km/h164 million years

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

Facts

  • Spectral type T9 (SIMBAD).
  • Its distance comes from a measured parallax. In the Sloan survey it shows only in the reddest filter, z, and it was picked out in data from the WISE infrared survey.

Where this comes from

  • Parallax 214.3 ± 2.8 mas (Kirkpatrick et al. 2021, ApJS 253, 7 — the 20-pc census of L, T and Y dwarfs)
  • 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).
