states that planets move in elliptical orbits with the sun at one focus. Think of the elliptical shape as a part of a cone. This is the shape of the orbit that becomes an inverse square force‚ which is an intensity in the gravity field. The eccentricity is the ratio of the distance between the foci to the major axis of the ellispe‚ which is basically the orbit of each planet. Since the formula is Ra= a(1+e) and Rp= a(1-e)‚ when e=0 for the orbit‚ we can then calculate the orbit for each planet. These

studies stars‚ planets and galaxies. Astronomers use the laws of physics to investigate the matter and energy of celestial bodies. They then apply the research findings to solve space navigation and communication problems and even discover new planets and stars. In 1512‚ Copernicus theorized that the planets orbit the sun and the race to uncover new planets began. Historically‚ most of the famous astronomers have been men‚ such as Galilei Galileo and Johannes Kepler. Other men have made planet discoveries

scientists have suggested that the planet Kepler-62f might be habitable for life. If that’s so‚ it could open up a legion of other theories suggesting life exists on other systems surrounding Earth. Judging by NASA’s history with lying‚ they very well could have known about aliens for years. Let’s hope they’re not dangerous.
