Yep.. That would be cool I wonder what we would look like on a triangular planet... would our appearance be different due also to the difference in the gravitational pull I would expect there to be if it were triangular?
Yes, you might just find yourself floating off into space somewhere.
It would be quite freaky at the pointy ends !!
Some people would weigh a lot more than others, they might also be shorter.
First of all, the shape of gravity wouldn't match the shape of the planet. Although the shape of gravity on a triangular planet (let's assume a triangular prism for the sake of simplicity) wouldn't be (nearly) spherical, as it is on Earth, most of the mass would still be concentrated around the center of the prism, so as C4M says, some people would weigh more than others.If we pretend, for the moment, that the sides were perfectly smooth and there was no atmosphere, a ball released at the top of one of the points would roll 'down' to the center of the face and then 'up' the other side. It's path would be straight, however.An atmosphere, and any water, would follow the shape of gravity.
Hi Karen. I said a ball would roll back up the other side, not water. As I said, water would follow the shape of gravity, which would more or less be the shape of a lobate sphere (roughly spherical but with lobes).The ball behaviour would be even more interesting with a true tetrahedral planet as it would be rolling from an apex to a base.
