How far, from the Sun

About 99.8 million light-years. To cross it:

  • Light99.8 million years
  • Voyager 1's speed1.77 trillion years
  • Driving at 100 km/h1,080 trillion years

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

Facts

  • About 100 million light years away; catalogues put it between 100 million and 113 million.
  • About 175,000 light years across, at the distance above.

Where this comes from

  • Distance from z0MGS (Leroy et al. 2019, ApJS 244, 24); range with HyperLEDA's best distance modulus; size from HyperLEDA's D25 at that distance
