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.
4) Most of the planets' spin (rotation) axes are roughly parallel to the Sun's spin axis. Since the planets orbit the Sun in about the same plane as the Sun's equator, this also means that most of the planets' rotation axes are roughly perpendicular to their orbit planes. Roughly here means within 30 degrees.
