Mars again can provide you with all your answers.


On Earth, ice ages take hold when the polar regions and high latitudes become cooler than average for thousands of years, causing glaciers to grow toward the mid-latitudes. In contrast, the Martian variety occurs when -- as a result of the planet's increased tilt-- its poles become warmer than lower latitudes. During these periods, the polar caps retreat and water vapor migrates toward the equator, forming ground ice and glaciers at mid-latitudes. As the warm polar period ends, polar ice begins accumulating again, while ice is lost from mid-latitudes. This retreat and regrowth of polar ice is exactly what Smith and colleagues see in the record revealed by the SHARAD radar images.

Also, another moonless planet :

Venus: Venus is rotating very slowly in a retrograde direction, opposite to the direction of planets like Earth. The north pole of Venus is pointed 'down' (southward); hence the angle between the rotational axis of Venus passing through its north pole and the line perpendicular to its orbital plane is 177.4 degrees.
