The planets, in order, are: Abnum α (tidally locked with its host star, Ishatum α), Abnum β (tidally locked with its host star Ishatum ω), Abnum γ (tidally locked with both stars), Abnum δ, Abnum ε, Abnum ζ (which somehow has liquid water and an extensive surface ocean with cloud cover), Abnum η (the only known planet in the system to have sentient life, also somehow has liquid water), Abnum θ (which somehow has extensive forests), Ükül α, Ükül β, Ükül γ, and, at ≈292,08 AU from the barycentre, Ükül δ. Ükül α, Ükül β, Ükül γ, and Ükül δ are all gas giants.
