Ep. 624: Small Rocky Bodies (Including Phobos & Deimos)

365 Days of Astronomy - Weekly Edition ·

2021/12/13

We've talked about the icy objects of the Solar System, today let's talk about space rocks. There's a surprising variety of rocky material in the Solar System, and each object has a story to tell about the history and formation of the planets, moons and other rocky bodies.

Are asteroids dangerous? Well, just ask the dinosaurs and they’ll tell you a sad story of fiery death. It turns out we’re in a shooting gallery of space rock and metal. And somewhere out there there’s one with our name on it. Should we be worried? Or are the risks so minimal to be irrelevant.

Funding for basic science has always been tricky business, coming mainly from universities, government, companies or wealthy individuals. But who knows how many fascinating discoveries were never made because of a lack of funding. And we now live in an era where regular people can come together to fund scientific discoveries.
