How far, from the Sun

80.8 light-years. To cross it:

  • Light80.8 years
  • Voyager 1's speed1.43 million years
  • Driving at 100 km/h871 million years

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

Facts

  • The planet is about seven times larger across than the white dwarf it orbits (Vanderburg et al. 2020, Nature 585, 363).
  • Its distance comes from a Gaia parallax: the tiny yearly shift in its position as the Earth circles the Sun.

Where this comes from

  • Gaia DR3 parallax 40.3931 ± 0.0506 mas, Gaia DR3 2146576589564898688 (Gaia Collaboration 2023, A&A 674, A1)
