Our neighbourhood in space
The Sun, Earth and Moon are connected by gravity and motion.

Picture in words: 1. Sun: The Sun is a star that releases light and heat.
2. Earth: Earth travels around the Sun. Gravity keeps its path curved.
3. Moon: The Moon orbits Earth and reflects sunlight; it does not make its own visible light.
4. Orbit: An orbit combines forward motion with gravity pulling inward.

One more wonder: This picture is not to scale: real distances are much larger than the objects.


Question: Why can we see the Moon?
Answer: It reflects sunlight
