Science
Physical
- Minimum mass (m·sin i)
- 3.39 × 10²⁵ kg · 5.68 M⊕
- Radial-velocity detection measures m·sin i; the true mass depends on the unknown orbital inclination.
- Radius
- Not measured
- No transit — radius is a model estimate; true size unknown.
Orbital
- Semi-major axis
- 7,539,733 km
- From the NASA Exoplanet Archive (radial-velocity orbit)
- Eccentricity
- 0.13
- From the NASA Exoplanet Archive (radial-velocity orbit)
- Inclination
- 0.00 °
- From the NASA Exoplanet Archive (radial-velocity orbit)
- Orbital period
- 7.2 days
- From the NASA Exoplanet Archive (radial-velocity orbit)
- Perihelion
- 6,559,567 km
- Computed from the orbital elements
- Aphelion
- 8,519,898 km
- Computed from the orbital elements
- Mean orbital velocity
- 76.2 km/s
- Computed from the orbital elements
Composition
- Bulk composition
- Presumed rocky/gaseous super-Earth (minimum mass ~5.7 Earth); never imaged.
- Cloud appearance
- Appearance based on ESO/M. Kornmesser's artist's concept. No spacecraft has imaged this world, so its real appearance is unknown — The banded clouds shown are a representation of its class, shown only in Visual mode; Realism shows a plain spectral colour.
Radiation & temperature
- Insolation
- 5.39 S⊕ · 5.39× the sunlight Earth receives
- Computed from Gliese 667 C's luminosity and the orbital distance (inverse-square; Earth's sunlight = 1).
- Equilibrium temperature
- 425 K (152 °C)
- Computed model value — not measured.
Discovery & history
- Method
- Radial-velocity detection (stellar wobble)
- Name
- Designated 'b' as the first planet found around its star, following the IAU convention of lettering planets in discovery order from 'b'.
The first planet found at GJ 667 C (2011-2012), from HARPS radial velocities.
