Aster System

Aster and its debris disk.

**Aster System** is a system of a white dwarf, 5 planets, 4 dwarf planets and other way smaller objects in **The Silky Way Galaxy**. It is one of the most known white dwarf systems in the entire **Silky Way** galaxy.

## Formation and Evolution

**Aster** formed 4 billion years ago. It was once an **A-Type** main sequence dwarf. 2 billion years ago it turned into a red giant, most likely swallowing some of its former planets. It then became a red clump star and then an AGB star. It was becoming more and more unstable. 1.5 billion years ago, it shed its outer layers, leaving a nebula behind. After cooling down, its core transformed into a white dwarf.

## Objects in the System

### Star

* **Aster** is a white dwarf. It's approximately 1.5 billion years old. It has a mass of 1.3 solar masses and a diameter of 12 260 km. It was an **A-type** star in the past.

### Planets

There are five major planets in the **Aster system**. Three icy terrestrial planets (**Epizon**, **Monach** and **Kryog**) and two ice giants (**Xechas** and **Mystir**). Almost all of them have natural satellites, except **Epizon**.

**Epizon** - **Fall from Grace**

Brief Description
Pronounciation: *e-pi-zon.* The first and smallest planet in the system. It had a thick atmosphere and oceans in the past, but lost them. Has no moons.

**Monach** - **Endless Desolation**

Brief Description
Pronounciation: *mo-nak.* The second planet in the **Aster system**. **Epizon's** twin. Has 1 moon called **Syntroph** and a very young, extensive ring system.

**Kryog** - **Icy Wastelands**

Brief Description
Pronounciation: *kry-og.* Third planet and the largest rocky planet. Has two moons called **Mod** and **Dimo**. It was an ocean planet in the past

**Xechas** **Lonely Dancing**

Brief Description
Pronounciation: *zee-khas.* Ice giant. Largest, slightly bigger than **Mystir**. Most massive. Has the most moons (**Megal**, **Endia**, **Mikr**, other smaller moons: **List of Xechas' Moons**) and possesses an extensive ring system.

**Mystir** - **Poisoned Clouds**

Brief Description
Pronounciation: *myst-eer.* Ice giant. Last planet. Second biggest. Has an extensive ring system and many moons (**Pagom**, **Den**, other smaller moons: **List of Mystir's Moons**). Has an unusual green color due to an unknown toxic compound.

### Dwarf Planets

In the **asteroid belt** of **Aster** and beyond **Mystir**, there are four dwarf planets. **Nanos**, **Picos** (both forming a binary system), **Mesai** and **Reiar**. **Reiar** is the only dwarf planet in the asteroid belt.

* **Nanos** and **Picos** (binary system)

* **Mesai** (Moons: a ring system)

* **Reiar** (Moons: **Etair**, **Aria**)

### Minor Planets

The system is abundant in minor planets, such as asteroids, trojans, damocloids and even some centaurs orbiting between the orbits of the ice giants. All of the planets in the system are known to posses quasi satellites and trojan asteroids. Two of the most massive planets in the system: **Xechas** and **Mystir** are known to posses big amounts of objects at their L4 and L5 lagrangian points.

* **Anili**

* **Ikos** (contact binary)

* **Trex**

* **Ligo** and **Imo** (binary system)

### Comets

The **Aster System** is rich in comet-like bodies. The most notable ones are **Thomas' Comet**, **Minmus' Comet** and **Trolligi's Comet**. All three of them periodically orbit **Aster** at regular intervals.

### Belts and Disks

* **Debris Disk:** The extensive debris disk around **Aster** is probably a remnant of comets and other small bodies that got ripped apart by **Aster's** gravity. The disk stretches out from 0.1 AU to 1 AU.

* **Asteroid Belt:** The asteroid belt is located between **Xechas** and **Kryog**. It is full of icy asteroids. It is also home to objects like **Ligo**, **Ikos**, **Anili** and **Reiar**.

* **Comet Belt:** The comet belt is located beyond the orbit of **Mystir**. It is home to comets, icy asteroids and damocloids. **Trex** and **Mesai** are the two largest objects of the comet belt. Most of the comets in the **Aster System** come from the comet belt, (hence the name) like **Thomas' Comet**, or **Minmus' Comet**. The belt stretches out from 18 AU to even 60 AU from Aster.

* **Scattered Disk:** The Scattered Disk consists of various small objects, debris, comets and damocloids. It is located beyond the Comet Belt and is the boundary between the system and interstellar space. It stretches out from 60 AU to 500 AU.

## Affiliation and Colonization

The **Aster System** is fully owned by the **Verdan Federation**. Although the Aster System is not suited for colonization due to its unfavorable conditions, the **Verdan Federation** has managed to build bases and outposts on the three terrestrial planets and their moons. There have been plans for their terraformation, but that would be extremely hard and unprofitable.

## Location

**Aster System** is located in the ring of the **The Silky Way**. The closest star to it is **Starrial** at a distance of 5 ly. The other close system to it is the **Klein System**.

## Future of The System

In the future nothing much will change in the **Aster System**. If a large object will pass trough the system, it is possible that the orbits of the planets will get disrupted and leave the system. If this doesn't happen, their orbits will slowly decay and they'll crash into Aster via gravitational waves. In few trillion years **Aster** will eventually cool down and turn into a black dwarf.

## Trivia

-**Aster's** name came from the greek word αστέρι (astéri), meaning star.

-The major comet's names are based off the names of users on the wiki: **Spacedragon II** (Also known as **The Minmus Derp** on Discord), **Trolligi112477-ww**, and me who is writing this, **ThomasLovesPancakes1**!
