Rare earth elements are heavier than iron. They are made by supernovae (exploding stars). In nature, fission of uranium238 creates very small amounts of radioactive promethium. Most promethium is synthetically created in nuclear reactors. Rare earth elements change through time in small quantities (ppm, parts per million).
