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

Star system features
g May be a binary, but companion is unconfirmed

Known planets
g Though there are no extrasolar planets confirmed, but star is considered a good candidate to contain terrestrial planets like the Earth.

Habitable zone
g The distance from the star where an Earth-type planet with liquid water would be stable is centered around 0.92 AU. At this distance, the planet would have an orbital period of almost 324 days.
g The star probably is not a good place for Earth-like life. First, it is too young to host any life-bearing planets. Secondly, about once a century is suffers from superflares. These coronal mass ejectionsrelease between 100 and 10 million times more energy than the largest flares ever observed on the sun, making the star brighten for an hour to a week by up to 20 times. If our sun were to produce a large superflare, Earth's ozone layer would be destroyed, and ice on the daylight side of moons as far out as those of Jupiter or even Saturn would be melted, producing vast floodplains that refreeze after the flare subsides.

Rana

Star type
g K0 IVe

Distance from Earth
g 29.5 ly

Star Service No.
g NA

Age
g 7.5 billion years (Started life as a main sequence F8 dwarf, but core hydrogen fusion has ceased causing the star to expand and cool as an active subgiant before becoming much brighter and larger "as a true giant star" through core helium fusion.). Another estimate places its age at 12.59 billion years.

Diameter/Mass/Temp (xSol)
g NA; 120% (subgiant); NA

Brightness (xSol)
g 276.4%

Metallicity
g Between 54 and 214 percent of Sol's abundance of iron

Known planets
g A: NA
g B: NA

Habitable zone
g A: Radial velocity analysis suggests that giant planets of one tenth to 10 times the mass of Jupiter do not exist within 0.1 to four AUs of Star A. Assuming that the spectroscopic companion B does not preclude a stable inner planetary orbit, the distance from Star A where an Earth-type planet would be "comfortable" with liquid water is centered around only 0.457 AU, between the orbital distances of Mercury and Venus in the Solar System. An Earth-type in such a water-zone orbit would probably would have a period of around 123 days or a third of an Earth year. Porto de Mello lists it as one of 13 nearby astrobiologically interesting stars
