55 Cancri d, formally identified Lipperhey as is an extrasolar planet orbiting the Sun-like star 55 Cancri A. It is around 40 light years away from Earth. The planet is similar to Jupiter in some regards.
Characteristics[]
Given the planet's high mass, the planet is a gas giant with no solid surface. Since the planet has only been detected indirectly, parameters such as its radius, composition, and temperature are unknown.
it is predicted that 55 Cancri d is covered in a layer of water clouds: the planet's internal heat probably keeps it too warm to form the ammonia-based clouds that are typical of Jupiter. Its surface gravity is likely to be about 4 to 5 times stronger than Jupiter.
