New Looking Forward to October-November Planetary notes By Alan Clitherow now online
New season winter 2025-2026
October 24th, 2025. Mark Booth, STFC, ROE – The Solar System Beyond Neptune
Neptune is the furthest planet from the Sun, but the Solar System does not end there. Beyond Neptune lies Pluto. Discovered ninety years ago and long thought to be alone. Now we know of thousands of comet-like objects surrounding the Solar System in what is called the Kuiper belt. These cold, dark and icy objects inform us of the history of the Solar System through their distribution and composition. Similar belts also encircle other stars and provide us with a way to infer the locations of unseen planets orbiting those stars. Near or far, these Kuiper belts can often tell us more about planetary systems than the planets themselves.
The Dundee Astronomical Society was formed in 1956 and is affiliated to the British Astronomical Association BAA (to whom we send observations). In addition the Society has a number of honorary members throughout the country.
We would normally hold member meetings once or twice a month at the Mills Observatory, Balgay Hill, Dundee in the months October through to March. The first part of the meeting consists of a talk lasting about an hour from a guest or member, followed by a short tea break, then a shorter session for members to make their contributions.
The Society has a healthy membership and welcomes new members. Please contact our Secretary for further information via the Links page.
All Friday meetings begin at 7:30pm at the Mills Observatory unless otherwise stated, members should arrive by 7:15 to ensure the talk starts on time. Thanks
