Question about making an object rotate

I have an image of a planet (globe) and was wondering how I would go about making it spin around like a globe does?

Can someone point me to a tutorial for that or explain to me how to do it?

Thanks

Make that globe a movie clip instance. Click once on the globe movie clip to make it selected and open the actions panel. Type this code in:

onClipEvent(enterFrame) {
     this._rotation += 5;
}

The higher your FPS the faster this will go. But you can also just make 5 a higher number.
