Gliese 317 c is a possible extrasolar planet [cite journal |url=http://fr.arxiv.org/abs/0707.2409 |title=A New Planet Around an M Dwarf: Revealing a Correlation Between Exoplanets and Stellar Mass |author= John A. Johnson, R. Paul Butler, Geoffrey W. Marcy, Debra A. Fischer, Steven S. Vogt, Jason T. Wright, Kathryn M. G. Peek |journal=ARXIV |year=2007 |volume= |pages=27 |accessdate=2007-07-07] approximately 30 light-years away in the constellation of Pyxis. The planet was announced in July 2007 to be orbiting the red dwarf star Gliese 317. The planet is a Jovian planet that is, at least, 83% the mass of Jupiter. The semi-major axis is unknown, relatively typical for unconfirmed planets. The eccentricity of the orbit is 42% and have orbital period of 7.4 years.
