Moving an object towards a clicked object

I've been attempting to code a situation where the player is represented by StarShip in the code and when you click on an in-game object, the StarShip moves to the object's position that was clicked on and stops. The code I have right now though has this error where StarShip just slides and never actually stops at the object's position that was clicked on. Any help would be great.

 //StarShip is the object that is moving when the user left-clicks.
 var StarShip: Transform;
 var PlanetLocX; //The X coordinate of the object StarShip is moving to.
 var PlanetLocY;
 var PlanetLocZ;
 var isClicked: boolean = false;
 
 function OnMouseDown () {
     PlanetLocX = transform.position.x;
     PlanetLocY = transform.position.y;
     PlanetLocZ = transform.position.z;
     isClicked = true;
 }
 
 function Update() {
     if(isClicked == true){
         //Move StarShip to the clicked object's position.
         StarShip.Translate(PlanetLocX* Time.deltaTime, PlanetLocY* Time.deltaTime, PlanetLocZ* Time.deltaTime);
         }
     }
