Matthew’s answer to “Why did you name the planet Petra?” > Likes and Comments

Not cryptic. I made that connection but didn't know if it was more complex.

I also know that Petra is a top tourist destination in Jordan and was trying to figure out how that might relate but couldn't come up with a connection that would make sense for it.

Nope, nothing more complex than that, I'm afraid. :-)

I imagine that the Petra in Jordan got its name for much the same reason that I used it.
