How can i predict the position of a rigidbody that has its velocity change based on the gravity equation?

so i have a simulation of planets with gravity and i need to be able to see where they are going to be later on in the sim (so i can set up orbits and such)

my code:

extends RigidBody

func _physics_process(delta):
	for other_object in get_tree().get_nodes_in_group("GravAffected"):
		if self != other_object:
			var force_dir = translation.direction_to(other_object.translation)
			var force = force_dir * SimSettings.GRAV_STRENGTH * (mass * other_object.mass / 
			translation.distance_squared_to(other_object.translation))
			var accel = force / mass
			add_central_force(accel * delta)

Do you have a concrete question?
