How far, from the Sun

About 2,770 light-years. To cross it:

  • Light2,770 years
  • Voyager 1's speed49.1 million years
  • Driving at 100 km/h29.9 billion 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 2015, by transit and radial velocity (NASA Exoplanet Archive).

Its planets

  • Kepler-432 b — 13 times Earth's width, a giant, Jupiter-sized or more; its year lasts 53 days; about 540 °C, hotter than boiling water; found in 2015 by transit.
  • Kepler-432 c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 410 days; found in 2015 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.
