Earth Rotation

This is a 3D animation showing the rotation of the Sun, Earth, and Moon.
- You can adjust the rotation speed; the time for a single rotation ranges from 1 second (fastest) to 200 seconds (slowest).
- You can also set them to rotate in the opposite direction—something not found in nature.
- You can change the angle of sunlight hitting the Earth and Moon in 30-degree increments.
- For the Earth's display, you can choose from "Day," "Night," "Globe," or "Terrain and Water Depth" (with options for April, July, October, and January).
