If those were pearls, I'd want that big one.

I'm sure you would but unfortunately you're stuck orbiting around the little yellow 'G'.

By the way, it's the Os and Bs that live short lives, go supernova when they die, and tend to leave neutron stars or black holes where their center used to be. They also seed the stellar dust clouds with heavy elements though, so we have to thank them for most metals and lots of elements our bodies require.

There used to be an old saying to remember the order of the star classes (in this picture from right to left): Oh Be A Fine Girl, Kiss Me. OBAFGKM. Of course lonely astronomers scanning the skies all night came up with many other pneumonic devices as well :^)
