17th May – The Pluto Story – Prof. Ian Robson

Dr Simon Oliver

Prof Ian Robson joins us to talk about Pluto, how it was discovered and how discovery and observations of KBOs eventually led the International Astronomical Union (IAU)  in 2006 to declassify Pluto from being a planet.

Although ‘what is a planet?’ might seem to be an easy question to answer, it turns out that the ensuing debate by professional astronomers was both complicated and fractious. The twists and turns of how Pluto finally came to be demoted by the IAU are revisited on a personal basis – astronomical democracy in action – or not, and what was the legacy from the decision.

Prof. Ian Robson from Science and Technologies Facilities Council joins us online to present this talk.
