Gliese 581 ... is a red dwarf star with spectral type M3V, located 20.3 light years away from Earth. Its mass is estimated to be approximately a third of that of the Sun, and it is the 87th closest known star system to the Sun. Observations suggest that the star has at least four planets: Gliese 581 b, c, d, e.

Gliese 876 is a red dwarf star approximately 15 light-years away from Earth in the constellation of Aquarius (the Water-bearer). As of 2008, it has been confirmed that three extrasolar planets orbit the star. Two of the planets are similar to Jupiter, while the closest planet is thought to be similar to a small Neptune or a large Earth.

Gliese 710

These 3 APODs are identical pictures with nearly identical explanations:

Gliese 710 is a red dwarf star in the constellation Serpens Cauda, with visual magnitude 9.66 and a mass of 0.4–0.6 solar masses.

It is about 63.0 light years from Earth, but is notable because its proper motion, distance, and radial velocity[1] indicate that it will approach within 1.1 light years (70,000 AU) from Earth within 1.4 million years, based on the latest Hipparcos data. At closest approach it will be a first-magnitude star about as bright as Antares.

Gliese 623a & 623b

These 2 APODs are identical pictures with identical explanations:

Gliese 623 is a dim double star lying 25 light years from Earth. It was photographed by the NASA/ESA Hubble Space Telescope's Faint Object Camera in 1994. The main star is 200 million miles from its neighbour, Gliese 623b which may be either a red or brown dwarf star.

Gliese 229a & 229b

http://apod.nasa.gov/apod/ap990324.html

Gliese 229 ... is a cool, red dwarf star about 19 light years away in the constellation Lepus. The star is known to be a flare star. In 1994 a substellar companion was imaged and in 1995 it was confirmed. Gliese 229B is a brown dwarf orbiting the star; although it is too small to sustain nuclear fusion, with a mass of 20 to 50 times that of Jupiter it is still too massive to be a planet. Gliese 229B was the first Substellar Mass Object to be unquestionably identified.

Gliese 436 is a red dwarf star approximately 33 light-years away in the constellation of Leo. As of 2004, the existence of an extrasolar planet orbiting the star has been confirmed. There are indications that there may be an additional low-mass planet in the system, however this is not yet confirmed.

Gliese 777 ... is a yellow subgiant approximately 52 light-years away in the constellation of Cygnus. The system is also a binary star system made up of two stars and possibly a third. As of 2005, two extrasolar planets are known to orbit the primary star.

Wikipedia also has articles on Gliese 33, 75, 105, 250, 570, 667, 673, 721 (a.k.a. Vega), 747, 783, 884, 892, and 3021.
