| http://www.w3.org/ns/prov#value | - Here is how I calculate this:gravity on a planet, Fp = G * m1* mp / rp^2gravity on Earth, Fe = G * m1 * me / re^2Fp/Fe = re^2 / rp^2 = 1 / 2.4^2 = ~0.17 The article does not state the planet's mass or density. scientists do not yet know if Kepler-22b has a predominantly rocky, gaseous or liquid composition, but its discovery is a step closer to finding Earth-like planets.
