The Earth, the Moon and the Sun

Our Earth is a beautiful planet in our solar system. The Earth has a natural satellite. It is the Moon. The Earth and the Moon move around the Sun.



The moon is caught between Earth and the space shuttle Discovery in this photo taken in 1988. This shuttle mission marked the return of U.S. Senator—and pioneering astronaut—John Glenn to space.

The sun is a star, a hot ball of glowing gases at the heart of our solar system. Its influence extends far beyond the orbits of distant Neptune and Pluto. Without the sun's intense energy and heat, there would be no life on Earth. And though it is special to us, there are billions of stars like our sun scattered across the Milky Way galaxy.
