How far, from the Sun

About 1,940 light-years. To cross it:

• Light1,940 years
• Voyager 1's speed34.5 million years
• Driving at 100 km/h21 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-653 c — 0.8 times Earth's width, smaller than the Earth; its year lasts 22 hours; about 1,800 °C, hot enough to melt rock; found in 2016 by transit.
• Kepler-653 b — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 15 days; about 550 °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.
