Legacy GM turn object1 around object2, fixed to object 2's surface

How can i make an object turn around another object with the same speed as the surface of said object is moving (like a tree on a planet turns fixed on the surface/outer radius on the planet with the planet). I can turn the planet/circle without problem (image_angle), but i have problems synchronizing turnrate and position of the "tree" (object i want to turn together with the planet/circle). help would be greatly appreciated.

You could change the centre point of the tree to be the same as that of the planet, then the angles will be the same, with no x and y offset required.
Otherwise, you'll need to use sin() and cos() to calculate the position based on the angle of the planet, and apply the calculated x and y offsets. Just remember sin and cos use radians, but image_angle is degrees.
