Detailed explanation-1: -The earth’s spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth’s axis points towards the sun, it is summer for that hemisphere. When the earth’s axis points away, winter can be expected.
Detailed explanation-2: -What is very interesting about Uranus is that the planet has an enormous 98 degree tilt on its axis. Basically, it is laying on its side with the poles receiving the direct sunlight. This makes for extreme seasons and when the Sun rises at one of the poles, that pole will receive direct sunlight for 42 years.
Detailed explanation-3: -Earth’s axis is currently tilted 23.4 degrees, or about half way between its extremes, and this angle is very slowly decreasing in a cycle that spans about 41, 000 years.
