Astronomy talks - Pluto and the outer Solar System
Tuesday 10th February 2026 from 19:00pm to 20:00pm
Princess Alexandra Auditorium
Yarm School, Middlesbrough, Cleveland, TS15 9EJ
Join Go Stargazing astronomer Dr Fred Stevenson for this one of a series of fascinating lectures in the Friarage Theatre at the Princess Alexandria Auditorium.
In this talk we will discuss Pluto and other worlds far from the Sun.
We will discuss why it was re-classified as a ‘dwarf planet’ but show that irrespective of how we define it the New Horizons probe revealed to us the most intriguing world – a surface unlike any other with its own family of ‘minimoons’.
We will also discuss the related and most distant worlds from the Sun – the trans Neptunian objects.
