Tahmaeraldus
Tahmaeraldus is a fictional planet featured in the science fiction novel "The Star Wanderer" by Arthur C. Clarke. It is described as a gas giant located in a distant star system, characterized by its immense size and turbulent atmosphere. The planet is notable for its unusual auroral displays, which are said to be visible from vast distances. Its atmosphere is composed primarily of hydrogen and helium, with trace amounts of other gases. No solid surface exists on Tahmaeraldus; instead, it is a world of swirling clouds and extreme pressures. The planet's immense gravitational pull influences the orbits of its numerous moons, which are believed to be rich in exotic minerals. Tahmaeraldus plays a significant role in the plot of "The Star Wanderer" as a navigational landmark and a source of scientific curiosity for the human explorers. Its extreme environment presents considerable challenges for any potential spacefaring civilization seeking to explore or colonize it. The novel suggests that the planet's core may harbor immense energetic forces.
