In 20**, a group of Superfen took the long journey out of LHS 2520, discovered a frozen, uninhabitable rock, a searing-hot super-jupiter gas-giant on a 2-week year orbit , and a dense asteroid belt right smack-dab in the middle of the goldilocks zone that was immediately named the 'Kryptonian Belt'.
There were no current signs of life. A small memorial plaque was left behind before they took the long trip home.
One of the supers took a few kilograms of the Kryptonian asteroids with him. The future story of this material became known as the "Kryptonit incident" later.
