Explain why Uranus experiences extreme seasons
What will be an ideal response?
Uranus rotates on an axis that is tipped 97.8 degrees from the perpendicular to its orbit, so its seasons are extreme. When one of its poles is pointed toward the Sun (a solstice), one would see the Sun above celestial pole, and it would never rise or set. As it orbits the Sun, the planet maintains the direction of its axis in space, and thus moves from pole to pole. At the time of an equinox on Uranus, the Sun would be on the celestial equator and would rise and set with each rotation of the planet. Since it takes 87 years for Uranus to orbit the Sun, each season would last approximately 20+ years.
