Explanation

If the axis were perpendicular to the orbit, the circle of illumination would pass through the poles, resulting in 12 hours of daylight and 12 hours of darkness everywhere on Earth every day. Therefore, the North Pole would experience a cycle of day and night, not permanent darkness or permanent daylight.
