Pluto Isn’t a Planet

In 2006, a new definition of the term planet demoted Pluto to a dwarf planet. But what does that mean for the way we think about space?

In 2006, the International Astronomical Union adopted a definition of a planet that demoted Pluto to just one of what is likely hundreds of dwarf planets in our Solar System. Exploring the remote Kuiper Belt, this lecture challenges us to think about what kinds of scientific questions are worth our attention, what it means to name something – and why Pluto is worth caring about anyway. 

A lecture by Professor Chris Lintott.
