Shooting from a rotating object.

Getting Started Newbie Questions
#1

I have an object that is an earth with a cannon. What I want to do is shoot a missile from the cannon’s position that will be almost always different. The missile needs to be shot forward to the outside of the display. There is any way of doing that?

(I can change the inicial position of the cannon if needed)
