Infinitely many. The north pole of course, and any point one mile south of which the distance around the world is an 1/n miles for n an integer >= 1.

If we consider perfect sphere as the shape of the earth then two poles satisfy the conditions

Consydering the earth...its posible on the poles..

"God" is wrong again. The south pole does not satisfy the conditions - it is impossible to travel south from the south pole.

The answer is also not 3 points exactly. The question does not ask how many points his path has but at how many places you can do that. This problem was answered correctly and succinctly by the first poster.
