Apparent path of the Sun 3D

The Earth rotates on itself and around the Sun. But from the Earth, it's the Sun that seems to revolve around the Earth from East to West. At noon (solar time), the Sun reaches its highest position in the sky. This position varies with the seasons. This is the Sun's apparent course.

This 3D animation shows the rotation and revolution of the Earth and Moon around the Sun. Imagine a stationary observer on Earth looking up at the sky. His field of vision, represented by the cone, rotates with the Earth. During the day, he sees the portion of the sky in which the Sun appears. At night, he sees the part of the sky not exposed to the Sun's rays. The Sun appears to cross the sky, but in reality it's fixed and the Earth rotates. The 2D image shows how the observer sees the Earth. 

The proportions of size and distance are not respected. The time scale is respected.
