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.
