This is your Astronomy Tonight podcast.

On this day, September 30th, in 1880, the astronomical world was set abuzz by the discovery of a peculiar little moon orbiting Saturn. American astronomer Henry Draper, while observing Saturn through his 11-inch refractor telescope in Hastings-on-Hudson, New York, spotted a tiny, irregular speck of light near the planet's rings. This turned out to be none other than Hyperion, Saturn's potato-shaped satellite!

Hyperion, named after the Titan of celestial light in Greek mythology, is quite the oddball in Saturn's lunar family. Unlike most moons, which are nice and round, Hyperion looks like a cosmic potato that's been through a celestial food processor. It's about 270 kilometers (168 miles) across at its widest point, making it the largest known highly irregular body in our solar system.

But wait, there's more! Hyperion isn't content with just looking weird – it also behaves strangely. This moon tumbles chaotically as it orbits Saturn, making it nearly impossible to predict its orientation at any given time. It's like a cosmic ballet dancer who's had one too many space cocktails!

The discovery of Hyperion opened up new questions about moon formation and the complex dynamics of Saturn's ring system. It's a testament to the ever-surprising nature of our cosmic neighborhood and the keen eyes of 19th-century astronomers armed with what we'd now consider relatively modest equipment.

So the next time you're stargazing and spot Saturn, give a little nod to Hyperion – the celestial spud that's been keeping astronomers on their toes for over 140 years!
