Good extrapolation
😁
Except for the mass and gravity relationship and the thinness of the atmosphere.🙁
The gravity is related to the acceleration constant of the ‘c’ density of mass, therefore the gravity will remain the same.
The thinning atmosphere will be replaced by the gasses and water vapour created by the expulsion of the hot magma into the oceans.
The expansion of the planet and the escaping gasses will cool the whole system, so in the future the Earth will be a cold place with very poisonous and humid atmosphere.
The atmosphere will still weigh about 5.1441*10^15 metric tons, but it will contain a lot of sulphur.😐
