Here's why:
* Mars: Mars has a tilted axis similar to Earth's, which causes different parts of the planet to receive varying amounts of sunlight throughout the year. This results in distinct seasons.
* Uranus: While Uranus's seasons are very extreme and last for decades due to its extreme axial tilt (almost lying on its side), it still experiences changes in sunlight and temperature throughout its year.
It's important to note that while other planets might experience slight variations in temperature due to orbital variations, these are not considered true seasons like those on Earth, Mars, and Uranus.
