Composition
- Bulk composition
- A super-Earth of minimum mass ~4.4 Earth near the warm edge of 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
- 0.312 S⊕ · 31% of the sunlight Earth receives
- Equilibrium temperature
- 282 K (9 °C)
Discovery & history
- Method
- Radial-velocity detection (stellar wobble)
- Name
- Designated 'b' 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').
One of two planets reported in 2014 from HARPS radial-velocity data.
