Notes: The light year distances for the nearest star systems taken from parallax data determined by the Research Consortium on Nearby Stars (or Recons). The sources for their determination were as follows:
- H) Hipparcos.
- Y) Yale Parallax Catalog.
- S) Soderhjelm 1999.
- T) Tinney 1996.
- 1) Discovered 2003; exact distance is still uncertain.
