The dark companion to Gliese 229 has been observed visually by
the Hubble Space Telescope. Orbital eccentricity is about .6,
which according to current thinking is extremely high for a
planet. Mass and luminosity, plus known spectra indicating
methane, rule out the possibility of this being a star.
However, surface temperature is estimated to be 750Kelvin,
which, while too cold to support fusion, is plenty hot enough to
give the object a noticeable glow.

Gleise 229 "b", lies on the boundry between the very largest
planets and the very smallest stars. Arguably, one might
consider it to be a "brown dwarf" star. I'm not dispossed to
doing so. In my own humble opinion, a star either is undergoing
nuclear fusion, or did so some time in the past (and is now
either composed of degenerate matter, or has experienced a more
extreme gravitational collapse). To my thinking, these are
planets, albeit at the very extreme edge of anyones criteria for
what constitutes a planet.

Gamma Leporis is a prime candidate for at least a habitable
planet orbiting GAM Lep B. K2V should be considered at the low
end of the habitability range, whereas GAM Lep A may in fact put
out too much hard UV to be considred habitable (I'm not
completely ruling it out, however). Separation of these two
stars is 900 AU, so one may assume stable orbits are possible
out to 180 AU around either star. Gliese 229 is the only star
in its "neighborhood" also within GAM Lep's neighborhood.
