We can simply look at newtons laws of physics, and a very important one, gravity. You see the sun is huge. how huge? Well the sun, compared to us, is so huge that over a million Earths can fit inside it, not to mention that the sun counts for over 99% of all mass in our solar system. So the sun is huge. Then you have gravity, gravity is when a bigger object pulls smaller object towards it which is why we stick to Earth and not float off. So why don't we just get sucked up into the sun? Well we are but Earth is in a constant free fall or orbit around the sun and we are slowly getting pulled in, but as we are pulled closer to the sun the Earth misses it. So thanks to Newtons first and second the mass of the Earth makes us resist the suns gravitational pull, but not for long as an object in motion will stay in motion until acted upon by a force. then the sun's gravitational pull grabs hold of the Earth and we go around again and again until we get too close to orbit the sun and are just pulled in altogether. By that time either everyone on Earth can fly off to distant planets or miserably burn up. The same goes for the satellites that orbit Earth and the planets that orbit the sun. I left out some important details or could just be flat wrong altogether so go on this website for the absolutes on orbiting. "http://www.au.af.mil/au/awc/awcgate/jplbasic/orbits.htm";.
