i just call it "bob"

LOL! Reminds me of Planet Bob from that animation movie my kids watched some time ago...they form a new planet and the "creator" decides to name new Earth Bob.

Conjunction (geocentric) : When 2 bodies or more are (almost) aligned from a point of view located on the surface of the Earth. (ex : Moon-Mars-Saturn)

Two bodies are always aligned, unless their location is exactly the same. I think you mean when 3 bodies ore more are (almost) aligned...
