Elliptical Orbits

This Teaching Astronomy and Space video clip, from the Institute of Physics (IOP), Teachers TV and the Science and Technology Facilities Council (STFC), illustrates a simple demonstration showing how the orbits of the planets form an ellipse around the sun. It also enables students to see why comets have a much more eccentric eliptical orbit.

The demonstration requires a cork board, piece of paper, two notice pins, some string and a pen.
