Mars Tilt. Of all the features of Mars, its axial tilt is most similar to Earth. Marsâ tilt is 25 degrees, just a fraction away from the Earthâs 23.5 degrees. And because of this tilt, Mars has seasons, just like the Earth. Of course, since Mars takes twice as long as Earth to orbit the Sun, the seasons are twice as long.
A planet's axial tilt is a measure of whether the planet is in prograde (the natural direction of rotation of most bodies in our solar system) or retrograde (the opposite, ie, from East to West) rotation. Tilt angle is measured relative to the orbital plane of a planet. A tilt between 1 to 90 degrees is considered prograde rotation (Earth's tilt is 23 degrees, in prograde rotation), a tilt of 90 degrees is considered perpendicular, and neither prograde or retrograde.
