Lacaille 9352 (Lac 9352) is a red dwarf approximately 3.52 pc or 11.74 light years from Earth's Solar System. This star has the fourth highest known proper motion, moving a total of 6.9" per year. (This is still a very small movement overall, however, as there are 3,600" in a degree of arc.) It is the tenth closest star system to the Solar System and is the closest star in the constellation Piscis Austrinus. Its closest neighbor is the EZ Aquarii Star System, 1.29 pc or 4.21 ly away. No Jupiter sized object could be detected by the recent research using the Hubble Space Telescope.
