Changes

Like 55 Cancri c and many extrasolar worlds, 55 Cancri d was detected through observing changes in the star's [[radial velocity]] though sensitive measurements of the Doppler shift in 55 Cancri's spectrum.

Like 55 Cancri c and many extrasolar worlds, 55 Cancri d was detected through observing changes in the star's [[radial velocity]] though sensitive measurements of the Doppler shift in 55 Cancri's spectrum.

55 Cancri d's distance is 5.77 AU from it's parent [[star]], just outside of the orbit of Jupiter in our solar system, at that distance, the planet takes 14 years to orbit.  Because [[radial velocity]] was used to discover the planet, only the lower limit of its mass can be determined, which is estimated as 3.385 times that of [[Jupiter]], although it may be more massive, most likely a gas giant.  55 Cancri d also has the largest inclination of all the planets in the system, with its orbit at 53 degrees in respect to the plane.<ref name="exo">http://www.iop.org/EJ/article/1538-4357/474/2/L115/5590.html</ref>
