Rare earth elements are heavier than iron. They are made by supernovae (exploding stars). In nature, fission of uranium-238 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).
