WebFrom the gravity standpoint, sure. Surface gravity is proportional to M/r^2, so you want planet mass M to be double as well. Area is proportional to r 2, so 2 x the surface area means sqrt(2) x the radius, which means 2^(3/2) or 2.82 times the volume.. That means the average density = M/V is 2/2^(3/2) = 1/sqrt(2) = 0.707 times that of Earth.

WebA pure white surface, approximated on Earth by freshly fallen snow, has an albedo of unity (or 100%), indicating that all the incident radiation is reflected. A black body has an albedo of zero (or 0%), since all the incident radiation is absorbed. Different features on a planet will have different albedos and they change over time. WebApr 10, 2024 · The average temperature of the ocean’s surface has broken another record as marine heat waves increase around the planet.

WebThe main worry would be to reconcile twice the surface with the same gravity. Twice the surface means sqrt(2) times the radius, which in turns means about 2*sqrt(2) times the volume. So we are looking at a planet with a volume of 2.8 times that of Earth. The problem is that such a planet would really need a low density to not have a higher gravity.
