Composition
- Bulk composition
- Presumed rocky or volatile-rich super-Earth (minimum mass ~6.5 Earth); never imaged.
- Cloud appearance
- Appearance based on ESO/M. Kornmesser's artist's concept. No spacecraft has imaged this world, so its real appearance is unknown — The banded clouds shown are a representation of its class, shown only in Vision mode; Realism shows a plain spectral colour.

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'.
Announced in 2020 alongside planet b from the RedDots/HARPS survey of Lacaille 9352.
