Solar System

While this wiki mainly focuses on Hume III itself, Hume III also has a solar system that needs addressing. The solar system of Hume III, more commonly referred to as the solar system of Iliosia, the system's sun, contains nine planets, from closest to the sun to farthest: Calidia, Vihrania, Hume III, Valkonia, Rubiinia, Xenonia, Radonia, Ruudukia, and Prazdinia.

## Calidia

Calidia is the closest planet to its star and the 4th largest, and is often compared to Venus or Io in our solar system. While it is the closest to the star like Mercury, it is the hottest in this solar system like Venus and has constant volcanic activity like Io. These volcanic eruptions come from the mantle like on Earth, though unlike on Earth, Calidia has large concentrates of sand deep under its surface, making its mantle made partially of a thick glass-like substance. The temperature in the mantle of this planet is hot enough to melt this and thus the eruptions are primarily consisted of melted calcium and carbon compounds that could be called lava and what is essentially molten glass. There are also often small concentrations of mercury in these eruptions. Calidia has no moons and is named after the Latin word for hot, calidi.

## Vihrania

Vihrania is the second closest planet to its star and the 2nd smallest. It is one of two life-hosting planets in the Iliosia system, the other being Hume III. As far as atmospheric and crust composition and size, it is actually more similar to Earth than Hume III, though it does not have nearly the biodiversity that Earth or Hume III have. There are only two kingdoms under one domain, those being simple plants and animals. The animals are mostly single-cellular but in some cases are larger, and the plants are entirely single-celled. It has very shallow oceans, being about 1 mile deep at their deepest point, and in some cases having entire seas that are just about 20 feet deep. Vihrania has no moons and is named after after the Finnish word for green, vihrea.

## Hume III

There is plenty on this wiki covering Hume III, given that this whole wiki is based around it. It is very diverse biologically and is smaller than Vihrania, making it the smallest planet in the system. It is in the "goldilocks zone" of Iliosia, making it relatively to Vihrania, only about 14 million miles away when the two are lined up. It has one moon, nicknamed "Little Hume", and is named after David Hume.

### **Little Hume**

Little Hume is Hume III's single moon, and like Hume III, it hosts life, though like Vihrania, it is not nearly as diverse as Earth or Hume III. The plants on Little Hume are blue, and there are no true animals, though there are microscopic organisms that feed on the plants. Because of this, plants often compete greatly for sunlight and water, making of most of Little Hume like a jungle in terms of foliage density.

### **Eclipses**

Like on Earth, eclipses can happen on Hume III, but unlike on Earth, they can happen in two ways: Solar eclipses, and Vihrania-Hume eclipses. Solar eclipses occur the same way as they do on Earth, having Little Hume block the sun, though Little Hume is closer to Hume III than our moon is to Earth, so the moon completely blocks out the sun during this eclipse as opposed to making a ring of light around the moon. Vihrania-Hume eclipses occur when Vihrania and Hume III line up perfectly, causing Vihrania to fully block Hume III from the sun and granting a more intense and prolonged eclipse than a simple solar one.
