The Hope and Fate system is the system which Aron belongs to. It is a binary star system between Hope, a yellow dwarf star, and Fate, a red dwarf star. The system contains a total of 15 planets, 9 orbiting Hope and 6 orbiting Fate, along with numerous dwarf planets and moons.

Hope, the larger of the two stars, has a diameter of about 1,383,000 kilometers while fate is much smaller at about 646,000 kilometers, making it roughly half the size. Consistent with this metric, Fate is also around 45% as massive as Hope. Due to these differences in mass and size the system has an stellar barycenter about 1.93 AU away from Hope. Fate, with its lower mass, orbits 2963 AU away from this barycenter, or about 0.0468 light years.
