For 10 points, name these trajectories that allow an object to keep moving around a celestial object because of gravitational attraction, exemplified by the motions of the moon and satellites.
The radius associated with one important one is calculated by taking the cube root of the quantity 86160 seconds squared times the mass of the earth times big G divided by four pi squared. Communication platforms that require a constant fixed service are often put into (*) geostationary and geosynchronous ones. The planets have elliptical ones around the sun.
