A model of a planet shows a satellite moving in an elliptical orbit about the planet. The closest distance from the centre of the satellite to the centre of the planet in the model is 3 m and the longest distance is 8m.
a) Determine a possible equation for the orbit of the satellite.
b) Sketch the orbit of the satellite showing the position of the planet.

mmhh, sure looks like they are just giving you the b and the a values of the general equation of an ellipse.
