WebSeveral unique exoplanets have been discovered this way, including some orbiting very distant stars in the Milky Way. ‘Iceball’ Planet Discovered through Microlensing Gravity, weak and strong. According to general relativity, gravity can be described as a distortion in the structure of spacetime. WebSurface gravity is proportioal to the mean density ρ, and to the radius r of the planet: g = 4 π 3 G ρ r, with G the gravitational constant. A planet with roughly the composition of Earth, and 3,000 times the mass of Earth would have about 3-times the Earth's radius, hence the 27-fold volume, and the 3000/27 = 111-fold density.
