#Apparently, the equations of General Relativity do not apply to the motions of extra-solar planets. Scientists are studying Gamma Cephei, a system of two stars and one known planet. When data from the Hubble Space telescope was analyzed, it was found that the observed orbital arrangement should not be stable.<ref>http://stardate.org/radio/program/gamma-cephei-iv</ref> | #Apparently, the equations of General Relativity do not apply to the motions of extra-solar planets.
