Gliese 674 b is an extrasolar planet approximately 15 light years away in the constellation of Ara. This planet orbits tightly around Gliese 674. It is a sub-Neptune-or-Uranus-mass planet either gaseous or rocky. It orbits as close as 0.039 AU from the star and takes only 4.6938 days to orbit. This planet has a similar eccentricity to Mercury (e=0.2). The discovery of the planet was announced on January 7, 2007 by using the HARPS spectrograph mounted on the ESO’s 3.6 meter telescope at La Silla, Chile.
