How far, from the Sun

About 1,850 light-years. To cross it:

  • Light1,850 years
  • Voyager 1's speed32.9 million years
  • Driving at 100 km/h20 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 2013, by transit (NASA Exoplanet Archive).

Its planets

  • Kepler-145 b — 2.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 23 days; about 600 °C, hotter than boiling water; found in 2013 by transit.
  • Kepler-145 c — 4.3 times Earth's width, Neptune-sized; its year lasts 43 days; about 440 °C, hotter than boiling water; found in 2013 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.
