How far, from the Sun

About 16,600 light-years. To cross it:

  • Light16,600 years
  • Voyager 1's speed296 million years
  • Driving at 100 km/h179 billion years

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

Facts

  • Its shape comes from SS 433's jets punching into the shell.
  • One published estimate puts it 5.1 ± 0.4 kiloparsecs away.
