Asteroids in the solar system could contain undiscovered, superheavy elements

Over the past few decades, scientists in the United States, Germany and Russia have figured out how to use special tools to combine two atomic nuclei and create new, superheavy elements. Heavier elements have more protons, or positively charged particles in the nucleus; some that scientists have created have up to 118. With that many protons, the electromagnetic repulsive forces between protons in the atomic nuclei overwhelm the attractive nuclear force that keeps the nucleus together.
