Using Gmm/r^2 we find that it should have almost exactly the same gavitaional pull as earth at the surface (89% g). That's neat. Means we could have a boat with

Using Gmm/r^2 we find that it should have almost exactly the same gavitaional pull as earth at the surface (89% g). That's neat. Means we could have a boat with a sealed cabin at the right pressure and sail around the ocean with basically normal gravity.
