WebFirst, it is probably due to Earth formation history. Even though, by angular momentum conservation, planets should have a rotation axis aligned with that of the Sun, their formation history, characterized by accretion and … WebInclination of the Earth’s Axis and its effects Axial tilt, also called obliquity, refers to the angle a planet’s rotation axis makes with the plane of its orbit. The Earth is currently tilted 23.5° from this plane, resulting in many remarkable effects, including the seasons around the planet. What caused this Obliquity?

Webthe surface of a cone. Give it a nudge, however, and the axis will start gyrating wildly around the vertical, its motion tracing a cone ( drawing ). The spinning Earth moves like that, too, though the time scale is much slower--each spin lasts one day, but each gyration around the cone takes 26 000 years. The axis of the cone is perpendicular ...
