Gliese 317 b is an 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 jovial planet that orbits about 95% the distance between Earth to the Sun. Despite of this, it takes about 1.9 years, corresponding to slow orbital velocity of 14.82 km/s.
