Notes: Figures do not necessarily indicate correct significant digits. Vmag is visual magnitude. Under notes a is semimajor axis for orbit (mean distance), e is eccentricity, and m is mass. Distances are in light years (LY), luminosity in terms of that of the Sun (LSun), semimajor axes for orbits (mean distances) in astronomical units, planetary masses in terms of Jupiter's mass (MJ). Estimated planetary masses are the most probable figure; in these cases, only m*sin i has been determined from radial velocity variations. Stars identified only by HIPPARCOS number (HIP) may be incorrectly identified as nearby stars.
