The root word is "anterior", which means either toward the front (in anatomy) or preceding in time. I may have been mistaken when I applied to term to planetary motion. It is a very common term in biology, and is used as an opposite to retrograde (say in transport of proteins up and down nerves). Apparently, this term isn't used in planetary observation. The most common term according to wikipedia is "direct motion". Apologies.

Ah, don't worry about it. Now I've learned two things!

you say

    transport of proteins up and down nerves

I didn't even know nerves had an 'up' or 'down'. Would this refer to being 'closer' or further from the brian(Going to keep that typo) or what?
