Prof Alan Fitzsimmons

IAA Zoom Lecture – Weds 4th November 19:30 – Prof Alan Fitzsimmons

“What makes a comet great?”


Hopefully, many members of the IAA saw comet NEOWISE this summer. Although it was a great comet to see, it wasn’t a “Great Comet”. That title is reserved to the best and brightest of the comets. But what is it about a comet that can make it a “Great Comet”? This talk will look at the physical and dynamical reasons that make comets “Great”, illustrated by previous apparitions of these magnificent objects.


Alan Fitzsimmons is a Professor of Astronomy in the Astrophysics Research Centre at Queen’s University Belfast. He saw his first comet in 1983 while walking to the pub, and hasn’t looked back since, find more info on He also still enjoys looking at comets.
