Wolf 1061 b
Planet· orbits the Sun
Wolf 1061 b - a hot rocky super-Earth (minimum mass ~1.9 Earth) whipping around the star every 4.9 days, too close to be temperate. Found from the star's wobble, so its mass is a minimum and its surface has never been seen.

Composition
- Bulk composition
- A rocky super-Earth of minimum mass ~1.9 Earth, too hot to be temperate; found only from the star's wobble, 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
- 7.25 S⊕ · 7.25× the sunlight Earth receives
- Equilibrium temperature
- 461 K (188 °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 three planets announced in 2015 from HARPS radial-velocity data - the innermost of the family.
