Uona

Uona.

**Uona** is the third planet in the Ovumus System, and the first and smallest gas giant there. It has 3 moons, all of which are airless save the largest, Minst. It also has earned the nickname of a gentle giant due to its oddly low wind speeds and rarity of large storm systems.

## Physical Characteristics

Uona is unique among gas giants. Instead of the bands normally present on such a world, Uona's slow rotation rate causes the formation of a more venusian cloud covering, leading some to confuse it with a large terrestrial planet given only its image. It is also slightly larger than expected, due to the high heat coming from its parent star. While small to medium-sized storms can form every so often, the giant ones often present on Jovoterra almost never form.

## Atmosphere

Like most gas giants, Uona's atmosphere mostly consists of hydrogen and helium. Due to its location, there are large water vapor clouds in its atmosphere instead of the ammonia clouds which would be found further out in the system.

## Rings

Uona does not really possess a ring system, but instead a collection of minor moons orbiting below the roche limit. These are likely held together by tensile strength, meaning they are fairly dense and contain useful materials. This means that they are all the site of at least some mining operations in the system.

## Rotation

As previously mentioned, Uona has a slow rotation, with a full rotation covering roughly 2.5 days. Its axial tilt is at ~18º and slowly precesses.

## Orbit

The orbit of Uona is more eccentric than most planets, varying its distance between 7.6 and 8.2 AU and bringing temperature shifts to it and its moons.

## Moons

Uona has two major moons and 72 minor moons

### Minst

Minst is the first and largest moon of Uona. Due of its large mass (0,2325 earth masses exactly), it helds to a fairly standard-pressure dominated by carbon dioxide and water vapor, a rarity seen to moons this close to their parent suns. On rare occations, it rains water in the highlands and the mountains where temperatures are low enough, forming puddles and even small transient lakes that evaporate again in the day to form clouds. Those transient puddles has been the subject of research on if life can surivive in the condition present on Minst.

#### History

It is believed that in the early days of the Uonan Lunar System that there were atleast a few other major moons that orbit Uona. Minst's formation and migration inwards disrupted that, ejecting a resonable majority and sending a few spiraling downwards towards the roche limit, resulting in the creation of the (now vastly thinned) ring of Uona. Whats left after this whole ordeal is itself and a single lucky major moon, that is currently known as Usona. Volcanism spikes in the migration, forming and building up an atmosphere it has. The ignition of Ovumus does not effect this moon by much, as the magnetic field of Uona pretty much protects it from receiving the majority of the ultraviolet radiation that enters the general location of Uona.

#### Presence of life

Minst holds the highest concintration of colonies in the whole of the Uonan Lunar System, for civilian, industrial, and scientific purposes. It is also the admistrative capital of every natural satellite that orbits Uona, despite not hosting the highest population (the "ring" does). Two large O'neill cylinders orbits Minst's L4 and L5 points, made from mining a whole asteroid.

### Usona

Usona is the second and smallest major moon of Uona. Being little more than a giant ball of rock, it only hosts a few minor colonial settlements and slight volcanic activity because of its relativly close orbit to Uona. This moon pontentially holds insights to the history of the Uonan Lunar System and the now long gone, other moons of Uona.

Usona is the only other surviving major moon of Uona, the others being ejected or shredded by the roche limit, thanks to the migration of Minst. Why this moon (and why the others didn't) survived the whole ordeal is not known but likely boils down by its relatively high mass compared to the other moons.

Usona is mostly sterile of any settlements, on its surface, in its hill sphere and its lagrange points. But where is free [whatever the equivalence of real estate in space] there will be people present. This moon is not the expection to that rule.
