Allerias has two moons, one about 1.7 times the size of Earth’s moon and the other about 0.6 times the size of Earth’s moon. The large moon would normally cause strong tides that could possibly damage the habitability of the planet, were it not for the strategic placement of the smaller moon around it. On average, the two moons are the ends of a 90 degree angle whose axis meeting point is the center of the planet. This keeps the tides very well balanced and healthy.
