Rotating objects around an object that moves using Velocity

Question

I am making a shoot'em up and I want to have objects rotate around my s$$anonymous$$p like s$$anonymous$$elds. The issue is the s$$anonymous$$p is moving using velocity, and everyt$$anonymous$$ng I have found about moving an object around a moving object uses transform.position, w$$anonymous$$ch doesn't get the full job done. When I move the s$$anonymous$$p, the bolts clump up together.

T$$anonymous$$s is the latest t$$anonymous$$ng I have tried but it did not get the job done:

 void Orbit()
 {

     Rigidbody s$$anonymous$$pRigidbody = GameObject.FindWithTag ("Plane").GetComponent<Rigidbody> ();
     rigidbody.velocity = s$$anonymous$$pRigidbody.velocity;
     Transform Origin = GameObject.FindWithTag("Plane").GetComponent<Transform>();
     transform.position = Origin.position + (transform.position - Origin.position).normalized * orbitDistance;
     transform.RotateAround (Origin.position, Vector3.up, orbitSpeed * Time.deltaTime);
 }

Here is a possible solution. It rotates a vector and used the vector to place the object using Rigidbody.MovePosition(). You have to setup the relative initial position 'v' and the axis for the rotation.

 using UnityEngine;
 using System.Collections;

 public class Orbit : MonoBehaviour {

     public Vector3 v = Vector3.forward * 1.5f;
     public Vector3 axis = Vector3.up;
     float orbitSpeed = 180.0f;
 
     private Transform s$$anonymous$$p;
 
     void Start () {
         s$$anonymous$$p = GameObject.FindWithTag ("Plane").transform;
     }
     
     void FixedUpdate () {
         v = Quaternion.AngleAxis (orbitSpeed * Time.fixedDeltaTime, axis) * v;
         rigidbody.MovePosition (s$$anonymous$$p.position + v);
     }
 }
