Lacaille 9352

system

Lacaille 9352 is one of the closest and brightest red dwarfs, 10.7 light-years away in Piscis Austrinus. An M1V star about half the Sun's mass, it is unusually magnetically quiet for its type and hosts a compact family of four confirmed planets found from its radial-velocity wobble.

How we know

Note
All four planets follow the NASA Exoplanet Archive (checked 2026-07-04): confirmed, but detected by radial velocity, so their masses are MINIMUM masses and their radii are model estimates — none has transited or been imaged. The map position is symbolic; the real distance is 10.72 light-years.

Discovery & history

Name
Named for the French astronomer Nicolas-Louis de Lacaille and his 1763 southern-sky catalogue number.

Recorded by Nicolas-Louis de Lacaille (published 1763); two planets were announced in 2020 and two more in 2026.

Where to find it — in Piscis Austrinus, the Southern Fish (IAU constellation chart). It is an unresolved point of light; its surface has never been imaged.
