109 Piscium, often cataloged HD 10697, is a yellow subgiant star approximately 106 light-years away in the constellation of Pisces. It is commonly thought that the star is similar to the Sun, but with a higher abundance of iron. As of 1999, an extrasolar planet has been confirmed to be orbiting the star.cite journal | url=http://www.journals.uchicago.edu/doi/full/10.1086/308981 | author=Vogt "et al." | title=Six New Planets from the Keck Precision Velocity Survey | journal=The Astrophysical Journal | year=2000 | volume=536 | issue=2 | pages=902 – 914 | doi=10.1086/308981]

Stellar characteristics

109 Piscium is a yellow subgiant star of the spectral type of "G3-5Va-IV". It is thought that the star has about 1.1 times more mass than the Sun, along with 1.1 times the diameter and 2.7 times the luminosity. The star appears to be about 1.41 times as enriched with elements heavier than hydrogen (based on its abundance of iron). 109 Piscium is a slow rotator and chromospherically inactive, believed to be around eight billion years old and may have already ceased hydrogen fusion at its core.

Planetary system

In 1999, a team of astronomers (lead by Geoffrey Marcy and R. Paul Butler) announced the discovery of an extrasolar planet companion (now designated 109 Piscium b) of 109 Piscium. The planet is thought to be at least 6.05 times the mass of Jupiter. However, because the method of detection relies on radial velocities using the Doppler technique only determines the object's minimum mass, companion 109 Piscium b may actually be a brown dwarf. Either way, 109 Piscium b is separated from 109 Piscium on average by 2.12 astronomical units (AU). It moves around the star in a circular orbit that takes over 2.9 years to complete.

Popular Culture

* In the 1983 Star Trek novel "The Wounded Sky" by Diane Duane, the USS Enterprise intentionally causes 109 Piscium to go supernova by entering warp drive too close to the star, in order to destroy a group of pursuing Klingon vessels. Captain Kirk experiences an uneasy sense that he may "get in trouble with Starfleet" over this arguably rash course of action.
