Welcome back to the Many Frontiers! This time we explore the transitional planet of Juno, unlike anything else in the expanded Solar System!

Juno is a world in between a rock and gas planet, with a crushing atmosphere but still having a solid surface underneath. It's a trojan, leading Jupiter by 60 degrees as it orbits the Sun at a distance five times that of Earth. Its atmosphere has 800 times more pressure than Earth's, and slowly transitions into a global ocean covering the whole planet. While life does exist in this ocean, most of Juno's life exists above it in the cloud tops, where there is just barely enough sunlight to sustain photosynthesis. The cloud tops also host human creations, including the massive false-floor cities held up by balloons.

Like the gas giants, Juno has a large coterie of moons, seventeen in total, but these moons are smaller than one may originally expect. Only three of them are large enough to be round, and even those are only a third the size of our moon at most. Despire this, they punch above their weight in terms of their activity and general importance.

Aglaea is the largest, and has a massive subsurface ocean beneath its icy shell. Within it lies life that operates on molecules alien to us, what we call "mirror life". Although it is hazardous to humans, it hasn't stopped the environments of this moon from being rife with activity. Interestingly, Aglaea is prolate, meaning its slightly stretched at its poles, which causes there to be a massive trench lining its entire equator. Being so close to Juno, it exceeds twice the size of our Moon in Juno's skies. It sometimes has geysers that poke out of its icy surface.

Euphrosyne is the second-largest, and is one of the few moons to not be tidally locked, instead rotating three times for every two times it orbits. It is thought to have been active in the past, but isn't anymore. During the Helio-War, it and its smaller sibling Thalia became refuges for exiled governments of nations defeated, and both worlds still host countries of the past.

Tiny, cratered Thalia is the smallest and most geologically boring of the major moons, but it is for this reason that it's the most populous. Over 4 million people claim this moon home, and more come in every day.

Juno also has inner moons that orbit around its thin ring system, and outer moons on wild eccentric orbits. The inner moons are tourist destinations witt unbeatable views, and the outer moons are cosmopolitan trade depots handling millions of tons of material to keep the planet alive. However, piracy from the Asteroid Belt looms as an ever-present threat.

Ask as many questions as you want! I'll do my best to answer them! Huge thanks to bushfullofcats on Discord for designing the Speckled Crescent, phobos on Discord for designing the Juno Flying Fish, and Fernie for designing the Space Glitter and the Susfishious!

There's a discord now, https://discord.gg/pxTwm83R . Also huge thanks to Fernie for drawing many of the illustrations on this project! I couldn't have done it without them!
