Wie er entdeckt wurde

Erster Planet, entdeckt 2020 durch Transit, Radialgeschwindigkeit und Transitzeitvariationen (NASA Exoplanet Archive).

Seine Planeten

AU Mic b — 4.8 times Earth's width, Neptune-sized; its year lasts 8 days; about 280 °C, hotter than boiling water; found in 2020 by transit.
AU Mic c — 2.8 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 19 days; about 150 °C, hotter than boiling water; found in 2021 by transit.
AU Mic e — 4.9 times Earth's width (estimated from its mass, not measured), Neptune-sized; its year lasts 33 days; found in 2025 by radial velocity.
AU Mic d — 1 times Earth's width (estimated from its mass, not measured), about Earth-sized — probably rocky; its year lasts 13 days; found in 2023 by transit timing variations.

Woher das stammt

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.
