Open Dome Event - An Evening with Kepler and Friends

Event icon
Public lectures

Looking into our night skies we can follow the motion of our planets and comets through our solar system. Astronomer and physicists have explained and predicted the paths objects follow in gravitational fields. Explore the voyage towards understanding planetary motion and their orbits with Dr C Castleton (NTU) in his talk An evening with Kepler and Friends - Planetary Motion and Gravity.

  • From: Thursday 30 April 2015, 8 pm
  • To: Thursday 30 April 2015, 10 pm
  • Location: CELS, Nottingham Trent University, Clifton Campus, Clifton Lane, Nottingham, NG11 8NS

Event details

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.

Booking is required for this event. While attending this event you consent to filming, photography and sound recording which may include you as a member of the audience and its use in publication or advertising distribution either printed or online without payment or copyright.


The event will start at 8 pm with the talk An Evening with Kepler and Friend - Planetary Motion and Gravity in CELS. Refreshments will be offered from 7.45 pm in the CELS foyer. Afterwards, visitors will get a tour of the NTU observatory and the chance to see interesting objects in the spring sky with the observatory's telescopes, small telescopes, and binoculars if the weather allows it.

If the weather is not good, a small planetarium session will be offered in the observatory pointing out objects of interest.
