Composition
- Bulk composition
- A roughly Earth-mass planet (minimum mass ~1.4 Earth) in the cooler, outer habitable zone; never imaged.
- Surface appearance
- Appearance based on ESO/M. Kornmesser's artist's concept. No spacecraft has imaged this world, so its real appearance is unknown — The surface shown is an artistic representation, shown only in Vision mode; Realism shows a plain spectral colour.
Radiation & temperature
- Insolation
- 0.258 S⊕ · 26% of the sunlight Earth receives
- Equilibrium temperature
- 182 K (-91 °C)
Discovery & history
- Method
- Radial-velocity detection (stellar wobble)
- Name
- Designated 'c' under the IAU convention that letters a star's planets 'b', 'c', 'd'... in the order they are discovered (the star itself is the unwritten 'a').
The outer of the two temperate planets found in 2022 around this nearby faint red dwarf.
