The Problem with Pluto

Planetarium closure 10 February-9 March 2019: We are excited to announce the Melbourne Planetarium will be upgrading its state-of-the-art visual system to one that is brighter and three times the resolution of the current system. The upgraded system will give you an even better, immersive and awe-inspiring astronomical experience. The Planetarium will be closed during this period.

When is a planet not a planet?

The Problem with Pluto joins Lucy Leavitt on board a research craft heading to the outer limits of the Solar System.

Their mission? To collect data to silence debate questioning Pluto's status.

On the way, Lucy learns how Pluto is different to the other planets, where Pluto belongs in the overall structure of the Solar System and the difficulties of defining what makes a planet.
