A view of another dwarf planet: Ceres

I guess I should know this, but there’s a dwarf planet between Mars and Jupiter called Ceres. Apparently, it’s been known about since the early 19th century. And NASA put together some images of it from a recent mission:

So how big is this thing? Here’s an image of various objects in the asteroid belt:

Using the moon as a reference point, Ceres would be the object numbered 1 on the far left. So that’s small and that means it isn’t a planet. It’s a dwarf planet. Like Pluto, which, I was surprised to learn not too long ago, is also smaller than the moon.

So Ceres is about as wide as Texas.

  1. The discoveries we are makong about Ceres are just stunning. I can’t help thinking that the term ‘dwarf planet’ is altogether far too clunky, though, because it has been applied to such a wide range of bodies with very different characteristics and origins. Hopefully the IAU will revise it.
