Tummeaa
Tummeaa is a fictional celestial body featured in the speculative fiction work "Chronicles of the Lumina." Within this narrative, Tummeaa is depicted as a gas giant located in a binary star system. Its atmosphere is described as being composed primarily of hydrogen and helium, with trace amounts of methane and ammonia, contributing to its characteristic swirling cloud patterns. The planet's immense gravitational pull influences the orbits of its many moons, which are themselves varied in composition and geological activity.
The "Chronicles of the Lumina" suggests that Tummeaa possesses a powerful magnetic field, which generates auroras
