how do i make an object go to a certain position?

I'm pretty new to Unity and i wonder how i can make an object go to a certain position. I have a button, and in its script i have an empty OnMouseDown thing (not sure what it is called). So i want to make the OnMouseDown to move a game object to a position. How do i do this?
Edit: I kind of want to make the game object glide to the new position.

 

When a mouse button event is triggered, you want to start a method in your script, that performs the move.
You want to probably use MoveTowards method.

Here's an example of it, see the Update:
https://docs.unity3d.com/ScriptReference/Vector3.MoveTowards.html

This will make the object glide smoothly over the time to the desired target location.

 

First two posts, both of them about the same and both of them in unrelated forums. Well.
