Composition

Bulk composition
Presumed rocky (~1.8 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 Visual mode; Realism shows a plain spectral colour.

Radiation & temperature

Insolation
1.45 S⊕ · 1.45× the sunlight Earth receives
Computed from GJ 1061's luminosity and the orbital distance (inverse-square; Earth's sunlight = 1).
Equilibrium temperature
304 K (31 °C)
Computed model value — not measured.

Discovery & history

Method
Radial-velocity detection (stellar wobble)
Name
Designated 'c' as the second planet found around its star, following the IAU convention of lettering planets in discovery order from 'b'.

The second of the three planets found in 2020.
