i'd be willing to put money on this tounge-in-cheek answer actually being the correct one.

yeah, I remember reading somewhere that A* is called A star because it was the "best" search. That is what happens when comp-sci people have an ego. We get stupid meaningless names. This needs more research though as it was a long time ago that I read that.

it is A* but it is'nt pronounced A asterisk hehe. The algorithm being referred to A is another thing I'd have only assumptions about. Even an Algorithm A has heuristics, but Algorithm A* has better heuristics.

Well, it was named A*, because it requires an "admissible" heuristic that never over-estimates to be optimal and complete. I assume the star was tacked on because of the fact that A* search is complete, optimal, and optimally efficient among all such best-first algorithms.
