2D faux gravity walk/stick to a planet

Question

I'm trying , to make a Player walk on a planet , through searching , I figured out that I can achieve this effect using Faux gravity , I tried to Implement it , but it's not working as intended:

Planet a StaticBody with a sphere collider:

extends StaticBody2D


var _gravity := 10.0

func attract(body : RigidBody2D, deltaTime):
    var gravityVector = (global_position - body.global_position).normalized()
    
    var rotation = Vector2.DOWN.angle_to((gravityVector))
    
    body.apply_central_impulse(gravityVector * _gravity)
    body.rotation = rotation

and the Player is a RigidBody2D with CustomIntegration turned on:

extends RigidBody2D

export var Attractor : NodePath
onready var attractor = get_node(Attractor)



func _integrate_forces(state):


    attractor.attract(self, state.step)
    
    var velocity = state.get_linear_velocity()

    if Input.is_action_pressed("ui_left"):
        state.set_linear_velocity(Vector2(-50, 0) )
    elif Input.is_action_pressed("ui_right"):
        state.set_linear_velocity(Vector2(50, 0) )
    

the Player seems to be rotated and attracted correctly , when I move from the Editor, but when I add a linear velocity to it , it start floating , how can make it work correctly?
