Composition
- Bulk composition
- Presumed rocky super-Earth (minimum mass ~3.8 Earth), in the 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
- 0.877 S⊕ · 88% of the sunlight Earth receives
- Equilibrium temperature
- 277 K (4 °C)
Discovery & history
- Method
- Radial-velocity detection (stellar wobble)
- Name
- Designated 'c' as the second planet found around its star, following the IAU convention of lettering planets in discovery order from 'b'.
Confirmed in 2012-2013 as a temperate-zone super-Earth - the robust survivor of GJ 667 C's disputed larger planet family.
