Lacaille 9352 (Lac 9352) is a red dwarf star in the southern constellation of Piscis Austrinus. With an apparent visual magnitude of 7.34,[2] this star is too faint to be viewed with the naked eye except possibly under excellent seeing conditions. Parallax measurements place it at a distance of about 10.74 light-years (3.29 parsecs) from Earth.[1] It is the eleventh closest star system to the Solar System[14] and is the closest star in the constellation Piscis Austrinus. The ChView simulation[15] shows that its closest neighbour is the EZ Aquarii triple star system at about 4.1 ly away.
