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 2011 durch orbitale Helligkeitsmodulation (NASA Exoplanet Archive).
Seine Planeten
KOI-55 c — 0.9 times Earth's width, about Earth-sized — probably rocky; its year lasts 8 hours; about 6,600 °C, hot enough to melt rock; found in 2011 by orbital brightness modulation.
KOI-55 b — 0.8 times Earth's width, smaller than the Earth; its year lasts 6 hours; about 7,500 °C, hot enough to melt rock; found in 2011 by orbital brightness modulation.
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.
