The Planetary Habitability Laboratory has made up some periodic tables of all of the confirmed and suspected exoplanets so far, plus planetary bodies in our own solar system.
Exoplanets are hot right now. In the popularity sense. Thermally, they’re also cold and medium. But ever since the first one was discovered nearly 26 years ago — or 9,457 days as of this writing — we’ve been fascinated by them.
