1 Sir Isaac Newton was an English mathematician and mathematician and physicist who lived from 1642-1727. 2  The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature.
Isaac Newton discovered that gravity controls the orbit of the planets and moons. Since a satellite is an object in space that revolves around another object, the earth is a satellite of the sun, just like the moon is a satellite of the Earth!
