Composition

Bulk composition
Presumed rocky (~1.1 Earth masses); 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
3.85 S⊕ · 3.85× the sunlight Earth receives
Equilibrium temperature
388 K (115 °C)

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'.

One of three planets announced in 2020 from radial-velocity data - the inner, warmest of the family.
