Typically not a rod but a glass tube, heat close the end, drop the planet (opal or other object being used as the planet in the tube. Heat close it up and place it where you want it.
At one time there was rods with crushed opal in them you could use to get the planets (small ones). I have one I purchased from Trev's Glass some time ago.
