Returns the radius of the sphere of influence of a celestial body in meters. It uses the mass (m, mparent), semi-major axis (a) and parent (mparent) parameters with {{Body data}} for the given body. Returns the second parameter, an empty string when not set, if the body has no parent object (like Kerbol).
