Voyager 1 mit der Geschwindigkeit, mit der sie sich im Jahr bis 2026-10-25 nach außen bewegte (JPL Horizons). Fahrt: ohne Pause, ohne je nachzutanken.
Wie er entdeckt wurde
Erster Planet, entdeckt 2013 durch Transitzeitvariationen, Transit und Radialgeschwindigkeit (NASA Exoplanet Archive).
Seine Planeten
KOI-142 c — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 22 days; about 360 °C, hotter than boiling water; found in 2013 by transit timing variations.
KOI-142 b — 3.4 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 11 days; about 490 °C, hotter than boiling water; found in 2013 by transit.
Kepler-88 d — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 4 Earth years; about −110 °C, below freezing; found in 2020 by radial velocity.
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.
