SOLVED: How to properly follow in high velocity in 2D?

So I have a script attached to the main camera to follow the player's exact position:

 transform.position = new Vector3(Target.GetComponent<Rigidbody2D>().position.x,Target.GetComponent<Rigidbody2D>().position.y, transform.position.z);

which works fine until the player's velocity gets really hight(I'm making a very open 2D space game, so the player maybe traveling very fast) then the camera lags behind the player as he's speed gets higher. how do I fix this? I need the player in the middle of the screen even in high velocities. thanks in advance to whoever responds, see illustration pic Below.

FIXED: I had the code under FixedUpdate(), changed to just Update().
