The Trappist Family of Planets has a hard core!

In February of 2017, a team of European astronomers announced the discovery

of a seven-planet system orbiting the nearby star TRAPPIST-1. Aside from

the fact that all seven planets were rocky, there was the added bonus of

three of them orbiting within TRAPPIST-1’s habitable zone. Since that time,

multiple studies have been conducted to determine whether or not any of

these planets could be habitable.

What’s up with the boring names?

I propose we call them Liesl, Friedrich, Louisa, Kurt, Brigitta, Marta, and Gretl. The most habitable is Kurt, because he’s so magnetic.

But the star, of course, is Maria.

Buh-DUM-dum.
