As Krypton's destruction approaches, Jor-El still has not built a rocket large enough to hold his family. With the planet coming apart beneath them, Jor-El and Lara put their two-year-old son in a model rocket, launch it just minutes ahead of Krypton's destruction, and send Kal-El to the planet Earth. Found by Jonathan and Martha Kent, an older couple with no children of their own, the child is anonymously left at a Smallville orphanage. Some days later, the Kents successfully adopt the toddler. They name the boy Clark Kent, using Martha's maiden name for his first name.
