During perihelion of the yellow star it is hot and stormy, during aphelion the oceans freeze over most of the planet. Because of the elliptical orbit of the world, and because the twin suns orbit within the orbit of the world, seasons are erratic. Residents of Ragny speak of four seasons, of variable length and intensity. Summer reflects the closest alignment of the hot yellow sun with Ragny. It can last 1 to 3 "period" (a native calendar element reflecting 1/16 of their year), and can occur in 10.
