What Causes the Seasons on Mars?

Mars has seasons because it tilts as it goes around the Sun, just like Earth.

Imagine Mars is a big spinning top that also moves in a circle around the Sun. When one side of the top leans toward the Sun, that side gets more warmth, that’s summer. When it leans away, it gets colder, that’s winter. The other two sides experience spring and fall, like Earth does.

Mars isn’t perfectly straight as it spins. It’s tilted at an angle, kind of like when you lean your body to the side while spinning in a circle. This tilt is why parts of Mars get more sunlight than others during its yearly trip around the Sun.

Sometimes, Mars is closer to the Sun, like how you feel warmer when you move closer to a fire. Sometimes it’s farther away, like stepping back from the fire. This makes the seasons on Mars not always match up with Earth's. For example, winter on Mars can be really cold because it’s also farther from the Sun at that time.

So, Mars has seasons because of its tilt and how it moves around the Sun, just like you have different feelings when you’re close to or far from a fire!
