Science
Physical
- Mass
- 9.97 × 10²⁴ kg · 1.67 M⊕
- Radius
- Not measured
- No transit — radius is a model estimate; true size unknown.

- Perihelion
- 7,674,371 km
- Computed from the orbital elements
- Aphelion
- 8,482,199 km
- Computed from the orbital elements
- Mean orbital velocity
- 45.1 km/s

Composition
- Bulk composition
- Presumed rocky (~1.7 Earth masses), in the habitable zone; 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
- 0.583 S⊕ · 58% of the sunlight Earth receives
- Computed from GJ 1061's luminosity and the orbital distance (inverse-square; Earth's sunlight = 1).
- Equilibrium temperature
- 242 K (-31 °C)
- Computed model value — in the temperate zone, but not measured.
Discovery & history
- Method
- Radial-velocity detection (stellar wobble)
- Name
- Designated 'd' as the third planet found around its star, following the IAU convention of lettering planets in discovery order from 'b'.
The outermost of three planets announced in 2020, and the one in the star's habitable zone.
