I want to make a world larger than earth for a story I want to write. Please can someone tell me about the different characteristics a world with a 20% larger radius would have; how much gravity it would have, how many hours the days would be if it rotated at the same speed as earth on the surface, how much surface area it would have and how much land ( with the same land to sea ratio as earth ) and other info about the physics of the planet what effects the larger radius would have.:
- How much gravity it would have
- How many hours the days would be if it rotated at the same speed as earth on the surface
- How much surface area it would have
- How much land ( with the same land to sea ratio as earth )
- and other info about the physics of the planet what effects the larger radius would have.
Also, the atmospheric pressure, and the speed of the atmospheric winds would be the same as Earth, as well as the density of the planet.
