(Ōts HēI ´•m) The Otz system is a multi-star system comprised of an eccentric ternary grouping orbited by a binary star system. The ternary group is composed of a neutron star OSI 00739+122C, a red giant (M2 III) OSI 00739+122A and a yellow dwarf (G3 V) OSI 00739+122B. The exploration team of the AMP Surveyship Mitzvah named the ternary grouping Ain, Ain Soph, and Ain Soph Aur respectively. The binary pair orbiting the ternary group is composed of an F1 V star OSI 00739+125A they called Keser and a brown dwarf (M9 Vb) OSI 00739+125B they named Tefireth.
The neutron star Ain in the ternary group has an extremely eccentric orbit around Ain Soph that is maintained by the gravitational attraction of Ain Soph Aur. This elliptical orbit causes Ain to come close enough to Ain Soph to strip some of the outer layers of the photosphere. The accretion to Ain’s surface creates a thermonuclear instability that causes Ain to flare and the accreted matter to be blown off. These explosions cause periodic shock waves and massive bursts of solar wind. The mean period of these thermonuclear instabilities is 2,640 standard years. Within this periodicity, there is a longer cycle. Every 26,400 standard years Ain’s orbital position places the explosion close to Keser and its planetary system. This proximity to the massive radiation storm causes transformational mutations in the Adeptii of Enochii.
Keser is also a member of a binary system. Tefireth, its partner, is a brown dwarf that accreted a diameter of 237,000 miles which was insufficient to achieve ignition of its stellar furnace. This resulted from the formation of the three gas giant planets that accreted from the protostar cloud outboard of Tefireth. Consequently, its only radiation is in the form of heat radiated in the far infrared.
The planetary system clustered around the Keser-Tefireth binary is comprised of eight planets, thirty-eight moons. Forty-one planetoids either accreted or have been captured in a debris ring stable zone balanced between the gravitational pull of Keser and Tefireth. This ring is situated between Geburah, the fourth planet, and Tefireth. The planets Keser 1 through Keser 4 were named Chokmah, Binah, Chesed, and Geburah. The remainder of the planetary system is composed of three gas giants and one gas supergiant planet named Hod, Netzach, Yesod, and Malkuth respectively.
Malkuth, it is theorized is another failed star that did not achieve sufficient mass to become a brown dwarf like Tefireth. Its eccentric, retrograde orbit is an indication that it may not have been born in the Otz system, but is a wanderer that became trapped in the Otz gravity well.
The chart below gives a few brief details of the number, astronomical and physical properties of the members of the star system.

The planetary structure of the Otz system is complex. In addition to its multi-stellar system structure, the Keser-Tefireth binary adds a second level of complexity. The Otz Chiim system is one of only a handful of nested planetary systems, and the first in which habitable planets have been identified.
The Otz system has a habitable zone that extends from c. 5.3 million km outside the orbit of Geburah to c. 8.6 million km beyond the orbit of Tefireth. This creates an area where water is in its liquid state. The four largest planets in the Tefireth system orbit within this habitable zone.
