Solar system 'Eitan (UHJ852)' comprises the star 'Eitan' and the retinue of celestial objects gravitationally bound to it: 14 planets and their 1013 moons, as well as asteroids, meteoroids, planetoids, comets, and interplanetary dust.

The principal component of this star system is the star 'Eitan', a red dwarf class star that contains about 98.04% of the system's known mass and dominates it gravitationally. Eitan is located more than 2490 lightyears from the center of the galaxy.

Reah, the fourth planet in this system, may feature life forms. Its average temperature is 253K (-20C) and it's atmosphere contains 15% of oxygen. One year on Reah lasts 435 days, one day lasts 22 hours. It's diameter is 10824 km, 0.8 times the diameter of the Earth.
