WebMar 18, 2024 · If you manage to pull down the average density to 5 g/cc, you can get to a radius of 7500 km with a gravity of 10.48 $m/s^2$. (Earth is at 5.5 g/cc with a radius of 6300 km). With 4.5 g/cc you can get to about 8000 km radius. However mind that it can be tricky to reconcile a carbon rich planet with an oxygen rich atmosphere. Share The standard acceleration due to gravity (or standard acceleration of free fall), sometimes abbreviated as standard gravity, usually denoted by ɡ0 or ɡn, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is defined by standard as 9.80665 m/s (about 32.17405 ft/s ). This value was established by the 3rd General Conference on Weights and Measures (1901, CR 70) and used to define the standard weight of an object as the … WebOct 1, 2024 · (1) m g = G m M R 2 where g = 9.8 m / s 2 and R is the radius of the earth.
