How to move object using Vector3.Cross?

 using UnityEngine;
 using System.Collections;
 
 public class Balance : MonoBehaviour {
     public float startDistance;
     public float newDistance;
     private Vector3 Line1;
     private Vector3 NewVector;
 
     void FixedUpdate () {
 
         newDistance = Vector3.Distance(transform.position, Vector3.zero);
         Line1 = Vector3.Lerp (Vector3.zero, transform.position, 0f);
         NewVector = Vector3.Cross (Line1, Vector3.up);
         
         if (newDistance<startDistance) {
 
             float random = Random.Range (0, 3);
             
             if (random == 1)
             //move to one side
             
             if(random == 2)
             //move to another side
         }
         
         startDistance = newDistance;
 
 
     }
 }

I need to move object in NewVector axis. How to? I guess i already have NewVector axis, but how to move object in it?
