Lacaille 9352 is a red dwarf star appearing near the southwestern edge of Piscis Austrinus, the Southern Fish. It was first listed in Abbe Nicholas Louis de La Caille's posthumous 1763 catalogue of stars he observed from 1750 to 1754 at the Cape of Good Hope. (Lacaille, who was first astronomer to systematically observe the entire night sky, also named 15 of the 88 currently-recognized constellations.) At magnitude 7.34, the star is somewhat too faint to be seen with the naked eye; but Lacaille observed it with just a 1/2" (8x) refractor.
Located 10.7 light-years from our Sun, Lacaille 9352 is the 10th-closest star to our Solar System, and is the closest in Piscis Austrinus. Its nearest neighbor in space is the EZ Aquarii system, 4.21 light years away. Lacaille 9352 has the fourth largest proper motion known, moving across the sky at 6.9" per year. It is a dim, cool, main-sequence red dwarf with a spectral type of M1.5 Ve, a mass 47% of the Sun's, about half the Sun's diameter, and 1.1% of its luminosity. Its has only about a tenth of the solar abundance of "metals", i.e. elements heavier than hydrogen.
A search for faint companions using the Hubble Space Telescope found no evidence of any large Jupiter- or brown dwarf-sized objects.
