Pluto is the farthest planet from the Sun (usually) and by far the smallest.
In July 1958, Superman journeys to Pluto to obtain some giant snowflakes, frozen so solidly that they will not melt on Earth, for inclusion among the collection of â€œspace trophiesâ€ which he is gathering for the Metropolis Museum so that they may be buried in the ground in a time capsule as a gift for the people of the fiftieth century C.E. (S No. 122/1: â€œThe Secret of the Space Souvenirs!â€).
Pluto the God
In Roman mythology, Pluto is the god of the underworld. Pluto was one of the gods who empowered a magical belt for Superman to use to defeat Zha-Vam.
