Known planets
g In 2007, a team of astronomers announced the discovery of a Neptune-class planet in an inner orbit; the following year, a different team of astronomers submitted a paper that apparently rule out the mass of a Neptune-sized inner planet but found evidence for a less massive "Super-Earth" companion in an tighter inner orbit; this Super-Earth is known as Gliese 176 b. This Super-Earth boasts a mass of 8.4 Earths with a diameter of 1-4 Earths and orbits at 0.66 AU every 8.78 days. Planet's temperature is estimated at 351° F.

Habitable zone
g Center of habitable zone is >0.088 AU; a planet may be able to hold water on its surface beyond 0.09 AUs
