![]() But why in elliptical orbits? Well most of the mass in our solar system is found in the Sun and so the Sun has the greatest gravitational pull in our neighborhood in space. ![]() Andrew M explained pretty well to another question how the solar system got moving at its formation and its been going ever since. you need a lot of mass involved before we start to notice it. And the force is actually a pretty small one. I think it makes more sense to think of gravity as a pull, not a push, because gravity is a force of attraction that exists between any objects with mass. You know what he called the force that keeps planets (and anything else!) from flying off in a straight line once they start moving- gravity. ![]() It's not such a simple question, at all! In fact until Newton came along and figured it out, nobody had a really good explanation for your really important observation, that the Earth and other objects in space going around the Sun follow a precise and predictable path, or orbit.
