55 Cancri A
55 Cancri d (abbreviated 55 Cnc d), formally named Lipperhey/ˈlɪpərhiː/, is an extrasolar planet in a long-period orbit around the Sun-like star 55 Cancri A. Located at a similar distance from its star as Jupiter is from the Sun, it is the fifth and outermost known planet in its planetary system. 55 Cancri d was discovered on June 13, 2002.
