HD 32518 is a 6th magnitude K-type giant star located approximately 390 light years away in the constellation of Camelopardalis. It is 1.13 times more massive, 10.22 times larger, and 41.2 times more luminous than the Sun. However, it has a lower amount of metals than our Sun and the age is older. In August 2009, it was found that this giant star has a giant planet.
