In our cabinet of meteorites – because everyone has one of those in an odd corner, right? – we have a number of surprisingly-dense space rocks. You can’t really hurt them, considering they’ve already been dropped far harder than any puny human can manage, so occasionally we get to pass them around.
Here we have the Plainview meteorite, from Hale County, Texas. Discovered in 1917, the original find weighed over 400 kg (a lot!), and our little chunk is a mere 184 g. Isn’t it adorable?
