1. Mars's Orbital Eccentricity: Mars has a much more elliptical orbit than Earth. This means the distance between Mars and the Sun varies significantly throughout the year. When Mars is closest to the Sun (perihelion), it receives more solar energy and experiences summer, which is shorter and warmer. When Mars is furthest from the Sun (aphelion), it receives less solar energy and experiences winter, which is longer and colder. This variation in distance creates a more pronounced difference in solar energy received, leading to longer seasons.
2. Mars's Axial Tilt: Mars has an axial tilt of 25 degrees, which is similar to Earth's tilt of 23.5 degrees. This tilt causes different parts of the planet to receive varying amounts of sunlight throughout the year, leading to seasons. However, the combination of Mars's axial tilt and its elliptical orbit creates a more extreme variation in sunlight received, leading to longer seasons compared to Earth.
In summary: While Mars's axial tilt is similar to Earth's, its more elliptical orbit creates a greater variation in solar energy received, resulting in seasons that are twice as long as Earth's.
