Video editing help

Hi all, hope you all had a great xmas

I have a question and Im hoping to find the answer on this forum, I’ll try to explain it as clearly as I can.

I am making a presentation for my company, the video recording is of the moon in the night sky,

now the camera zooms into the moon, zooms out, and moves left and right

What I want to do is place some text on to the moon so it looks like the text is built on the surface of the moon, the graphics and getting the text to look as if its built on the moon isnt the problem, the problem is fixing the position of the text onto the surface of the moon…

What im doing at the moment is I have the video on the timeline, then I create another layer onto which I paste the text, but the syncronization between the moon and the text is not fixed, the moon moves left right, in and out of the screen, whilst the text remains motionless, is there a way to attach the text on to the surface of the moon somehow to it moves along with the movement of the camera?

Im using flash cs3 at the moment, but any recommendations or a tip pointing in the right direction would be grateful, even if you could tell me if there is a specific name for the effect that I am trying to achieve

Thanks in advance
