巨無霸地球

巨無霸地球（mega-Earth）的定義是質量至少是地球10倍的岩石質類地太陽系外行星。巨無霸地球的質量較超級地球（質量為地球5到10倍的類地行星或海洋行星）更大。「巨無霸地球」一詞於2014年發現系外行星克卜勒-10c時首次出現。該行星的質量相當於海王星，但是密度卻高於地球Sasselov, Dimitar (2 June 2014) Exoplanets: From Exhilarating to Exasperating , 22:59, Kepler-10c: The "Mega-Earth", YouTube The Kepler-10 planetary system revisited by HARPS-N: A hot rocky world and a solid Neptune-mass planet , Xavier Dumusque, Aldo S.
