Good catch! According to SIMBAD, Wolf 359 is at 2.35 pc = 7.67 light
years. At V=13.5, it is too faint for Hipparcos. Its distance would
make it the fifth nearest star after the Sun unless there are others
missing. The list in _AQ_ also appears to be a Hipparcos list, so it
too will be incomplete for faint stars.

Zeta Tuc also appears to be missing.

Dan, ad nauseam

A) Our sun is just an avergage star.

There are 71 stars within 20 light years of the solar system, of which only
4
(Alpha Centauri A, Sirius, Procyon, and Altair) are brighter than the sun.
Most are M dwarfs. Here's the list (from the hipparcos catalog)


Actually there are 106 stars within 20 light years. Also, this is a hot
area of research, and it is anticipated many more will be found. This
information comes from my favorite www site, The Atlas of The Universe by
Richard Powell. Richard does a very good job updating the nearest stars
list, I think it is one of his interests.
