Tupan Patera (Io)

Thunder god of the Tupi-Guarani Indians of Brazil.

Tupan Patera is an active volcano on Jupiter's moon Io. Tupan consists of a volcanic crater, known as a patera, 79 kilometers across and 900 meters deep. The volcano was first seen in low-resolution observations by the two Voyager spacecraft in 1979, but volcanic activity was not seen at this volcano until June 1996 during the Galileo spacecraft's first orbit.

A patera is an irregular crater, or a complex one with scalloped edges. Usually the dish-shaped depression atop a volcano. On Io they are named after words for fire, sun or thunder; volcano gods, heroes, goddesses or mythical blacksmiths.
