. The planet is orbiting the K-type giant

Giant star

A giant star is a star with substantially larger radius and luminosity than a main sequence star of the same surface temperature. Typically, giant stars have radii between 10 and 100 solar radii and luminosities between 10 and 1,000 times that of the Sun. Stars still more luminous than giants are...

HD 102272 b

HD 102272 b is an extrasolar planet approximately 1,200 light-years away in the constellation of Leo. The planet was discovered orbiting the K-type giant star HD 102272 in 2008. The planet was discovered by the radial velocity method, using the Hobby-Eberly Telescope. Another planet, HD 102272...

, was also discovered orbiting the same star. Although there is evidence for the existence of this planet, data is insufficient to unambiguously determine its orbit. The discovery was announced in June 2008. It's thought to have at least 2.6 times the mass of Jupiter.
