**Rhea** is the second largest moon of Saturn and the ninth-largest moon in the system, she is the second smallest body who obtains hydrostatic equilibrium, after dwarf planet Ceres. She was discovered in 1672.

she is really shy, and has the same personality as Saturn and Neptune, she got really sad about how Dione took off her arms when she was young, she also does not like crime and horror fiction due to the fact that she doesn't like blood.

## Physical Info

Rhea is an icy body made out of 25% rock and 75% ice, before the *Cassini-Huygens* mission took place she was assumed to have a rocky core, but in a paper published in 2007 indicated that her moment of inertia coefficient was 0.4, she has an almost homogeneous interior.

her triaxial shape is consistent in hydrostatic equilibrium, she would be capable of sustaining a liquid water ocean underneath her skin due to heating caused by radioactive decay.

## Features

her features resemble those of Dione, with leading and trailing hemispheres, her average temperature she spends is 99 degrees K (-174 degrees Celsius, and -281 degrees Fahrenheit).

she has a heavily cratered surface, with the exceptions of a few Dione-type chasmata of fractures on the trailing hemisphere and has a very faint line of material on her equator, she has two very large impact craters on her "Anti-Cronian" side (the side facing away from Saturn), their names are Tirawa and Inktomi, Tirawa is roughly comparable to that of the Odysseus basin on Tethys, and Inktomi (also called "The Splat"), is one of the youngest craters on Saturn's inner moons.

Her surface can be divided into two geologically different areas based on crater density, the first part contains craters larger than 40 kilometers, and the second areas has craters under that size, this suggests that a major resurfacing event happened to her during her birth, the leading hemisphere is heavily cratered and uniformly bright like on Jupiter's moon Callisto, her craters lack the high relief features Moon and Mercury have, the cratered plains are four billion years old on average, the trailing hemisphere has a network of bright swaths on a dark background with few visible craters. these bright areas might be material ejected by ice volcanoes early in her lifetime when her interior was still liquid, Dione however has an even darker trailing hemisphere and similar but more prominent bright streaks.

## Birth

Rhea, like her other friends, we're born in a co-accretion disk, similar to how the planets are born

there is a model where Titan formed in a series of giant impacts, Rhea and Iapetus where born from these impacts

## Atmosphere

in 2010, NASA announced the discovery of a tenuous atmosphere, an exosphere, it consists of carbon dioxide and oxygen of roughly 5 to 2.

## Possible ring system

in 2008, NASA announced that she could have a ring system, marking the first discovery of rings around a moon, her rings' existence was inferred by observed changes in the flow of electrons trapped by Saturn's magnetic field as *Cassini* passed by Rhea, dust and debris could extend out to her Hill sphere, but no evidence of ring material was found orbiting her

solid bodies can stably orbit around her, they won't be stable around Dione and Tethys because they so much closer to Saturn and have smaller Hill spheres, or on Titan because of drag from his dense atmosphere

## In fiction

* in the movie *Independence Day: Resurgence*, humanity builds a defense outpost on her
* in the *Red Rising* book series, 60 years prior to the events of the books, she rebelled against the society and as a lesson to the other moons, she got "glassed" (the surface bombarded until she got so hot that she formed a layer of glass-like rock)
