Astronomy assignment - Essay Example These observations were more strong evidence that Earth is not the center of all things and that at least one planet orbited the Sun. The weight will change by 21 kg since the mass remain constant because the center of gravity is constant. The gravitational force between you and earth is divided into two components. One is the centripetal force required to keep you moving in a circle, and the rest is your weight. So if the radius increases so does the centripetal force. Thus, the weight goes down. The weight will change just proportional to the earth radius changes i.e. by one third of its current measure. There is gravity near the earth orbit keeping in mind that Earths gravity affects everything at or near the planets surface. We feel the force of gravity on Earth through our mass, and that force also translates into a downward pull of 9.8 meters per second squared However, in deep space, thousands of light years from any object, there is no gravity since the higher you go, the weaker and no gravitational force exists (Chaplin,
