How far, from the Sun

About 66.1 light-years. To cross it:

  • Light66.1 years
  • Voyager 1's speed1.17 million years
  • Driving at 100 km/h713 million years

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

How it was found

  • First planet found in 2022, by radial velocity (NASA Exoplanet Archive).

Its planets

  • HD 149806 b — 12 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 45 Earth years; about −200 °C, below freezing; found in 2022 by radial velocity.

Where this comes from

  • NASA Exoplanet Archive, Planetary Systems Composite Parameters (fetched 2026-11-02). Composite values: where a planet's size or mass was not measured, the archive estimates it from the other.
  • This research has made use of the NASA Exoplanet Archive, which is operated by the California Institute of Technology, under contract with NASA under the Exoplanet Exploration Program.
