Most globes are made to tilt at an angle of 23.5 degrees to match the actual tilt of the earth in relationship to our sun. Incidentally, it is this tilting of the earth relative to the sun, rather than its changing distance from the sun, that causes the seasons to change and gives us more daylight hours at certain times of the year.
