===== Terran perspective =====
From the perspective of sentient terran humanoids, Siur is the source of alot of speculation. In an opposite orbit, Siur remains out of view of Terra at all times, though the existence of the planet is known as its moons and their orbits have been plotted. It has similar appearance and size to Terra, though this is not known by Terrans. Despite the mystery, Siur is considered to be a "sister" planet to Terra
