Part of the Chaotian Era
Erebrean Period - Hyperitian Period - Titanomachean Period
The Hyperitian Period is the first period of the Chaotian Era, and of the Hadean Eon. The Hyperitian is the first geocentric period on the geologic time scale. The Hyperitian begins with the formation of the proto-Earth Tellus (and the coinciding first light emitted from the sun, which was brighter than it is today due to a gravitational collapse) and ends with a continued series of protoplanetary collisions. Before the Hyperitian was to end, the Early Heavy Bombardment had began, though it would not be nearly as devastating as the Late Heavy Bombardment to follow.
The Hyperitian is not further subdivided into epochs.
