names = GJ 4052 b, HIP 89844 bHD 168443 b is a planet seven times as
mass ive as Jupiter. Given the high mass, this planet is likely to be agas giant , or possibly a smallbrown dwarf depending on the orbitalinclination . It orbits closer to its star than Mercury does to the Sun, and its surfacetemperature is likely to be very high.References
