HD 10180 c

Extrasolar planet in the constrellation Hydrus

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.

While planet c does not exist in any mean motion resonances, both planets with adjacent orbits (b and d) share near resonances with c.^{[citation needed]}
