[3] In July 2014 the International Astronomical Union launched NameExoWorlds, a process for giving proper names to certain exoplanets and their host stars.

[1] Astrometric observations made with the Hubble Space Telescope suggest that the outer planet 55 Cancri d is inclined at 53° with respect to the plane of the sky.

Since the planet was detected indirectly through observations of its star, properties such as its radius, composition and temperature are unknown.

It orbits in the so-called "habitable zone," which means that liquid water and life could exist on the surface of a possible moon.

[9] It is also possible that 55 Cancri f is a "temperate ice giant" or hycean planet due to its orbit and possible hydrogen-rich composition.
