Ishtar Gate is an ocean planet located 4 hops away from Promision.
Analysis[]
Due to its bonus in the production of nanotubes as well as the superior output of Nanotubes Domes over Nanotubes Factories, this will be the player's primary and likely only source of nanotubes for most of the player's journey across the Perseus Arm. Due to energy restraints associated with ocean planets, however, not many can be built, but only enough to construct ships requiring nanotubes at a fairly reasonable pace depending on Hydrology levels.
It is wise to avoid building any energy-intensive buildings such as Uranium Shell Assemblers or low output energy-consuming buildings such as Electrolyzers. Also, unlike Aequoreas, the high orbital distance renders Solar Central useless at 6.38 energy per second.
