GJ 1061

system

GJ 1061 is a small, quiet red dwarf 12.0 light-years away in Horologium, host to three confirmed planets found from its radial-velocity wobble. The outermost (d) lies in the temperate zone where liquid water could exist.

How we know

Note: Three confirmed planets; their masses are measured but their radii are model estimates (none transits). Real distance 11.98 light-years.

Discovery & history

Name: A catalogue designation (Gliese-Jahreiss 1061).

Its three low-mass planets were found in 2020 by the CARMENES and HARPS/Red Dots radial-velocity surveys.
