Sunlight comes from an enormous Sun, yet reaches Earth from almost the same direction. Explore how distance changes the angles of the rays.
Things to try
- Press Play and follow the changes in size and distance.
- Compare the ray angles at true distance and at the deliberately compressed distance.
- Pause or scrub the timeline, and watch Earth spin to follow day and night.
