Orrery (calculating tellurium)


Type: MundanePrice: 200 gpWeight: 2 lbs.Slot: Slotless


This complex mechanism simulates the angles and relative distances between one or more bodies in a solar system in relation to the system's star with marks or spheres on moving gears or arms. Anyone consulting an orrery gains a +2 circumstance bonus on Knowledge (geography) checks involving bodies it models and on Survival checks to navigate the void of space. An orrery can be used in combination with a sextant on a clear night to determine the time on any of the stellar bodies it models. Any orrery can be used as a focus component for the augury spell in place of that spell's normal focus.

Orreries come in many shapes and sizes and with a variety of functions in mind.
