“Callisto is the outermost of the Galilean satellites, and orbits beyond Jupiter’s main radiation belts.”

“Callisto is the most heavily cratered object in the solar system.”

“Callisto’s surface is extremely heavily cratered and ancient — a visible record of events from the early history of the solar system. However, the very few small craters on Callisto indicate a small degree of current surface activity.”

“Callisto is the second largest moon of Jupiter and is about the same size as the planet Mercury. Whereas Io has the youngest surface in the Solar System, Callisto has the oldest. Its crust dates back 4 billion years, just shortly after the solar system was formed. Its ancient history is evident by having the most cratered surface of any moon in the solar system.”

Callisto’s heavily cratered surface only gives it the appearance of having the oldest surface in the solar system when actually it represents just the oldest of the Galilean satellites.
