Composition
- Bulk composition
- A cooler outer super-Earth of minimum mass ~2.3 Earth; 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
- 0.169 S⊕ · 17% of the sunlight Earth receives
- Equilibrium temperature
- 148 K (-125 °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 two planets announced in 2017 around this nearby red dwarf.
