Orbits of the inner planets of the HD 10180 planetary system, using the orbital configuration from an eight-body (the star and seven planets) Newtonian model taking into account tidal dissipation.
HD 10180 c is an
exoplanet approximately 130
light-years away in the constellation
Hydrus.[2] It was discovered in 2010 using the
radial velocity method.[2] With a minimum mass comparable to that of
Neptune,[3] it is of the class of planets known as
Hot Neptunes.[citation needed] Dynamical simulations suggest that if the mass gradient was any more than a factor of two, the system would not be stable.
