A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 5 x 1010 m (inside the orbit of Mercury), at which point its speed is 9.6 x 10* m/s. Its farthest distance from the Sun isbeyond the orbit of Pluto. What is its speed when it is 6 x 1012 m from the Sun?

A spaceship needs a lot of fuel to reach the geostationary orbit. Compute the required height for a geostationary orbit and the potential energy for one kilogram (the potential of the geostationary orbit). Compare that value to the energy content of rocket fuels, i.e. energy per kilogram. What is the potential to leave our planet completely?
