Solar System objects more massive than 10 21 kilograms are known or expected to be approximately spherical. Astronomical bodies relax into rounded shapes ( spheroids ), achieving hydrostatic equilibrium , when their own gravity is sufficient to overcome the structural strength of their material. Visa mer This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for … Visa mer The following objects have a mean radius of at least 400 km.
