Kahje

Kahje is a massive planet, about twice the size of Jupiter. It is an ocean planet, with 90% of its surface covered in water. Yet small islands dot the landscape of this Jupiter-sized planet. As the homeworld of the hanar, a race of terran jellyfish, this planet is also dotted with small Prothean ruins. The atmosphere is perfect for life; it consists of traces of ammonia, but most of it is oxygen, hydrogen, and nitrogen, which gives it an Earth-like atmosphere. Currently, the scarcity of land on Kahje makes it uninhabitable by humans.
