,Rotate a gameobject around another while being attracted by its gravity

I have a game object ( satellite ) which is it is being attracted by another object(Sun). the satellite rotates (clockwise ) by holding mouse click, and on space key press(Jump), a force pushes the satellite against the gravity.
if satellite rotates around the sun whiling jumping, releasing the mouse button causes the satellite to rotate a bit back.

how to fix this?
is there any better way to achieve this gravitational rotation?
Tnx in advance.

void FixedUpdate()
    {

        if (Input.GetMouseButton(0))
        {
                transform.RotateAround(center.transform.position, Vector3.back, 50 * Time.deltaTime);
        }

        if (Input.GetKeyDown(KeyCode.Space))
        {
            direction= transform.position - center.transform.position;
            GetComponent<Rigidbody2D>().AddForce(direction* 100 * Time.deltaTime);
        }
            axis = center.transform.position - transform.position;
            GetComponent<Rigidbody2D>().AddForce(axis * 100 * Time.deltaTime, ForceMode2D.Force);         
    }

Im not sure if your question is how to make the satellite once you stop holding go straightforward to the sun, if thats the case you can set satellite velocity to vector3.zero when Input.GetMouseButtonUp(0) for making sure it doesnt continue previouse speed.

also save the rigidbody in a var in the start since you are accessing in fixedupdate and will cause performace issues.
