"Professor Trelawney bent down and lifted, from under her chair, a miniature model of the solar system, contained within a glass dome. It was a beautiful thing; each of the moons glimmered in place around the nine planets and the fiery sun, all of them hanging in thin air beneath the glass. Harry watched lazily as Professor Trelawney began to point out the fascinating angle Mars was making to Neptune."
—Harry Potter's Fourth year Divination class[src]

Orreries are models of the sun, planets and moons of the solar system, used for studying Astronomy. Sybill Trelawney used one of all nine planets (including Pluto) while teaching Astrology during Divination in 1995.[1]
