The joy of Wikipedia and Weird Terrain

Somehow the course of my Lie Groups take-home exam took me to the wikipedia article Caloris Basin.

It never ceases to amaze me (sorry for the cliché) how easy it is to get between two seemingly unrelated wikipedia pages just by following links. I wanted to make sure antipodal was the right word for describing opposites points on a circle, I know it is for a sphere but wasn't sure if its correct terminology for other dimensions. The page has a list of antipodal points on earth and then on other planets and the moon.

As it turns out, Caloris Basin is antipodal on Mercury, to a location known as "Weird Terrain".
