HIP 70849 is a 10th magnitude K-type main sequence star located approximately 78 light years away in the constellation Lupus. This star, which resembles a brighter red dwarf, is smaller, cooler, dimmer, and less massive than our Sun. In 2009, a gas giant planet very much like Jupiter was found in orbit around it.

Planetary system[edit]

HIP 70849 b is an extrasolar planet orbiting the star. It has more than five times the mass of Jupiter and takes more than 3000 days to orbit at a semimajor axis of more than 3.5 AU.[2]
