Force and Motion: Facts. Motion makes the world go 'round. Motion makes the moon go 'round too. In fact, motion makes lots of things go. When we think of motion we often think of cars, bicycles, kids running, basketballs bouncing and airplanes flying.
What are stars made of? Basically, stars are big exploding balls of gas, mostly hydrogen and helium. Our nearest star, the Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb. Even though it is constantly exploding in a nuclear reaction, the Sun and other stars are so large and have so much matter in them that it will take billions of years for the explosion to use all the fuel in the star.
Planets do not produce light, light is produced by suns / stars, planets only reflect that light. Actually Jupiter does produce light, only it's in the infrared segment of the spectrum and we can't see infrared. Some planets do create light! Earth does. Because the sun is the only strongest light force and the stars are to weak to have their own bright lights because they are scatter through out the solar system. It is impossible to have a planet to have light without a sun and moon.
