Early Greek astronomers attempted to explain planetary motion using combinations of spheres. These became more complex until Kepler orbits were described as ellipses. From this time onwards motion in gravitational fields seems to have always resulted in a certain set of shapes. "But why?", many Open Dome visitors have asked in the past.
Dr C Castleton (NTU) will be following our exploits in gravitational motion in the footsteps of Kepler and his other famous friends. In his talk An Evening with Kepler and Friends - Planetary Motion and Gravity our visitors will be introduced into the fascinating world of ellipses, parabola, and hyperbola. All the knowledge that lead us to arrive at Rosetta, swing into orbit around Ceres and travel to Pluto. This talk will be followed by a brief introduction on what is visible in this month's sky.
