• Light5,200 years
• Voyager 1's speed92.4 million years
• Driving at 100 km/h56.1 billion years

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

Facts

• KIC 9663113 b has an equilibrium temperature between −50 and +50 °C.

How it was found

• First planet found in 2015, by transit (NASA Exoplanet Archive).

Its planets

• KIC 9663113 b — 4.6 times Earth's width, Neptune-sized; its year lasts 570 days; about −9 °C, below freezing; found in 2015 by transit.
• Kepler-458 c — 4.2 times Earth's width, Neptune-sized; its year lasts 21 days; about 530 °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.
