GJ 3323

system

GJ 3323 is a small red dwarf 17.5 light-years away in Eridanus. Two super-Earths circle it, announced in 2017 from the star's radial-velocity wobble; the inner one lies near the warm edge of the temperate zone. Both masses are minimums.

How we know

Note
Two confirmed planets (NASA Exoplanet Archive, checked 2026-07-07), found by radial velocity — minimum masses, no measured sizes. Map distance is symbolic; the real gap is 17.5 light-years.

Discovery & history

Name
A catalogue designation (Gliese-Jahreiss 3323); also Luyten's LP 656-38.

Its two planets were announced in 2017 from ESO's HARPS radial-velocity data.

Where to find it — in Eridanus, the River (IAU constellation chart). To the eye it is a single point of light; no telescope has imaged its surface.
