How far, from the Sun

About 1,640 light-years. To cross it:

  • Light1,640 years
  • Voyager 1's speed29.2 million years
  • Driving at 100 km/h17.7 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 2016, by transit (NASA Exoplanet Archive).

Its planets

  • Kepler-787 b — 1.3 times Earth's width, about Earth-sized — probably rocky; its year lasts 22 hours; about 840 °C, hotter than boiling water; found in 2016 by transit.

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.
