Matuma-Anama System

Matuma-Anama, *(Mah-too-Mah Ahh-nah-Mah)* is a star system composed of two small, faint dwarf stars, at a distance of 210,000 light years from the sun, located comfortably within the Small Magellanic Cloud. It is a P-type binary system, home to seven rocky worlds, and one ice giant. This system gets its name from the inhabitants of Keikonami, named after their god of life, and goddess of light.

## Overview

Despite the name, Matuma-Anama is not the commonly used name when describing the system, it is the name of the stellar barycenter in which the two stars orbit. The more commonly used name by the inhabitants of Keikonami is Matunamah Alaho *(Mah-too-Nah-mah All-Ahh-hoe)* translating to "Solar System" or "Home System" in their language, although for scientific exploration it is referred to as Matuma-Anama. Matuma-Anama was named in the inhabitant year of 23, only 23 years after they established a proper timeline to begin keeping time properly. The system has a diameter of 45.62 AU. The stars which make up the system are both smaller than the sun in diameter and mass, being a K-class orange dwarf, and a M-class red dwarf star. Located over 210,000 light-years from Earth, these two stars are invisible to the naked eye, and even to most deep sky telescope equipment. Matuma-Anama has a combined mass of over 1.2x the sun's mass, with 99.7% of all the mass being retained within the two stars at the center. This system hosts 8 planets, 7 of them being rocky, terrestrial, with Earth sized masses or less and only one of them being an ice giant. One of these planets also hosts life, an abundance of different ecosystems and has an interesting chemistry makeup. There are tens of thousands of asteroids that orbit these two stars, some being no smaller than a boulder, and some being as large as entire cities.

## The Stars

### Katanama Anama

*(see main article Katanama Anama)*

Katanama Anama *(Kah-Tah-nah-Mah Ah-Nah-Mah)* or also known as Matuma-Anama A, Is the largest star in the Matuma-Anama system, having a mass of 78% that of the sun. It is also the most massive object in the system. It is a modest K-type orange dwarf star, being only 74% the sun's diameter. It is a relatively active star, sometimes unleashing very powerful and dangerous solar flares, which can increase the star's luminosity drastically. Usually though, it shines with the energy of 0.37x suns and has a surface temperature of 5044 Kelvin.

### Katanama Matuma

*(see main article Katanama Matuma)*

Katanama Matuma *(Kah-Tah-Nah-Mah Mah-Too-Mah)* also known as Matuma-Anama B, is the smaller binary partner of Katanama Anama. It is a dim, low-mass M-type star, a small and cool red dwarf star with a surface temperature of 3720 Kelvin, much cooler than its larger sibling. It's low mass and cool nature doesn't stop it from being a very active star, with frequent solar flares and periodically dimming and brightening, it is much more active than Katanama Anama. This star has a mass of 44% that of the sun, along with a diameter of also 44% of the sun. Despite its mass and diameter, it shines with the energy of only 2% that of the sun, not contributing to much of the light given off of the binary two. These two stars complete orbits around their barycenter every 2.6 days.

## Asteroid Regions

Matuma-Anama has hundreds of thousands, possibly millions of large and small objects orbiting around these two stars, which pose a threat to life in the system, along with wiping out anything that may exist on any planets in the system. These asteroids are monitored closely by the inhabitants of Keikonami, and in turn, two main regions of asteroids have been discovered, but surprisingly there has been little evidence of any comets or large icy objects with highly elongated orbits that orbit the Matuma-Anama barycenter. Some of these objects are smaller than small rocks and boulders, and some asteroids are the size of entire cities, and there are theorized to be small, dwarf planets hiding within these asteroid belts, although no evidence or detections of such objects have been made. Below is further information of these asteroid belts.

### Imagitori Aleho

Pronounced *(Ima-gee-tore Al-ehh-hoe)* translating to "Hot rock belt", Is one of the two main asteroid belts orbiting the Matuma-Anama barycenter. There are over 100+ confirmed large asteroids, and thousands of smaller asteroids that orbit here, in the image to the right shows the large and tracked objects (Gray dots) but excludes the smaller objects due to the vast number of them. This asteroid belt is the smaller of the two, with the closest asteroids being only 0.13 AU from the barycenter, and the farthest being 0.16 AU from the center. The closest planet Weilehamo orbits within this asteroid belt, and in history, large asteroids have been recorded striking the planet. The two inner planets have been known to fling asteroids out towards the outer edges of the system, when these objects pass too close and the gravity of Weilehamo or Tamina throws them off course. This has posed a risk to life on Keikonami in the past, but in recent years asteroid orbits have become more stable, and not many large objects are expected to be shifted on a direct course with Keikonami. The largest of these objects within Imagitori Aleho is dubbed "1 Akomohama" pronounced *(Ah-ko-Mo-ha-Mah)* which means "wandering soul", is the largest discovered object in Imagitori Aleho, with a diameter of approximately 69 kilometers. Luckily however, this asteroid poses no threat to life on Keikonami, as its orbit does not intercept any planets or potentially large objects.

### Mak'toko Aleho

Mak'toko Aleho *(Mak-toe-ko Al-ehh-hoe)* which directly translates to "Ice Belt" is the larger and farthest asteroid belt in the Matuma-Anama system. This asteroid belt contains almost ten times the number of large asteroids compared to Imagitori Aleho, and many smaller asteroids which aren't being tracked actively. This asteroid belt has an estimated 100,000 asteroids over 100 meters in diameter, and plenty more smaller ones. It was given its name because all the asteroids are approximately -90 °C or below. These asteroids also have lots of surface ice and are believed to be 50% or more composed of frozen water. They have their cold and icy nature due to their distance from Matuma-Anama, with the closest asteroids orbiting at a distance of 1.26 AU, barely outside of Keikonami's orbit, and the farthest of these asteroids being at a distance of 3.63 AU, being at the inner edge of Tata'oma's orbit. Crammed in the middle of Mak'toko Aleho is the planet Maheho, which is subject to a lot of asteroid collisions and impacts. The density of these asteroids makes it difficult to send probes and spacecraft through, due to the number of asteroids that come in close proximity to the probes. No probes have ever been lost, but navigating through it is much more difficult than navigating through Imagitori Aleho. There are believed to be several dwarf planets hiding throughout Mak'toko Aleho, but no evidence has ever been found supporting these claims. The largest object discovered is "499 Akanohala" *(Ahh-Kah-no-ha-la)* translating to "Frosty Rock" in English. It is the largest discovered asteroid, at 159 kilometers in diameter, it is a planet killer asteroid, but luckily, it orbits in-between Maheho and Tata'oma, posing no threat to life on Keikonami. The abundance of rare minerals and frozen water makes the Mak'toko Aleho asteroid belt a popular subject of research.

## The Planets

The Matuma-Anama system is home to eight unique and well-studied worlds, one with life, and its own intelligent civilization. Most of the planets in this system are Earth-sized, terrestrial worlds, excluding one ice giant planet only a bit smaller than Neptune. The closest planets to the two stars are very hot and rigid, while some planets are temperate and have the right conditions for life to develop, and the outer worlds are frigid, icy wastelands with nothing more than nitrogen atmospheres, icy landscapes and possibly underground oceans. Every planet is unique in its own way and has its own extensive history.

### Weilehamo

*(see main article Weilehamo)*

Weilehamo, pronounced *(Way-Leh-hah-Mo)* Is a hellish, and arid planet. It gets its name from the inhabitants of Keikonami, named after their "Goddess of Hell". Weilehamo is very similar to Venus, the differences being its size and mass, along with its atmosphere mass. The planet has a diameter of 78% that of the Earth, about 9963 kilometers in diameter, and has a mass of only 52% of the Earth. Weilehamo is tidally locked to the barycenter, completing one orbit every 12.9 days. It is the 7th largest planet in its system, and has 4 small dwarf moons, the largest of which being only 300 kilometers in diameter. Weilehamo is the second hottest planet, with an average surface temperature of 584 °C, creating absurd weather on the surface of the planet. It is known to rain down liquid magma on the day side of the planet, meanwhile the dark side is very hot due to heat scattering in Weilehamo's atmosphere. This planet is an interesting subject of research due to its crazy weather patterns and mountainous terrain.

### Tamina

*(see main article Tamina)*

Tamina is the second planet in the Matuma-Anama system. It gets its name, Tamina *(Ta-me-nah)* From the inhabitants of Keikonami, named after the God of Summer. Tamina is a hellish, rigid world with seas of molten lava and rain of magma, averaging a surface temperature of around 670 °C, even hotter than Weilehamo. Tamina takes 28.7 days to orbit around the barycenter, and like Weilehamo, it is also tidally locked. Tamina is very similar to Earth in size and mass, having 94% the diameter, (12080 km) and 86% Earth's mass. This planet has the thickest atmosphere in the system, having 510 times Earth's atmospheric mass. The clouds on Tamina are so thick that light barely reaches the surface, and heat gets trapped in the atmosphere, which is what gives this planet its hellish conditions. Tamina also has 7 small moons, the largest being only 37 kilometers in diameter. Tamina is a hard planet to study due to its surface conditions, most probes will be destroyed once entering due to the very high atmospheric pressure and molten temperatures. To date, only 4 probes have successfully landed on Tamina's surface and transmitted back any data.

### La'omana

*(see main article La'omana)*

La'omana *(Lah-oh-Mah-nah)*, is the third planet in the Matuma-Anama system. Its name comes from the God of the ocean in Inhabitant mythology. La'omana is a boiling ocean planet, with the oceans being composed almost all of water, but also mixed in with liquid sulfur dioxide. Unlike Tamina or Weilehamo, La'omana is not too hot in terms of temperature, having an average temperature of 101.1 °C. La'omana is slightly bigger than Earth having 1.18 times the diameter. It has 1.47 times the mass of Earth, allowing it to retain its thick, Nitrogen rich atmosphere. 9 small moons orbit La'omana. La'omana orbits the barycenter every 127.1 days and has a rotational period of 9.2 days. It is not tidally locked, so it has a proper day/night cycle. Many orbiters have been sent to La'omana to study its atmosphere and oceans, and 2 floaters have been sent to study the ocean composition, to see if there are any traces of life in this planet's oceans.

### Keikonami

*(see main article Keikonami)*

Keikonami *(Cake-oh-Nah-me)* Is the fourth planet from the Matuma-Anama barycenter, and the second largest planet in the system. Keikonami's name originates from the inhabitants of this world, meaning "Home". Keikonami is a super-earth planet, being 1.35 times larger than Earth with a diameter of 17254 kilometers. Its mass is 3.2 times that of Earth, giving the planet a surface gravity of 170% that of Earth. A year on Keikonami lasts 1.05 Earth years, and a day only lasts 11 hours on the planet. Keikonami has 20 moons, one of which is spherical, stabilizing the planet's 9-degree axial tilt. Along with its average surface temperature of 24 °C, it makes the planet a great place for life to evolve and flourish. Keikonami is unique in its system for having oceans composed entirely of water, along with life that has visibly changed the appearance of the planet. Intelligent life also exists here, being as advanced are as humans are today, looking off into the stars and wondering what's out there. Keikonami has lots of different weather patterns giving the planet a stable temperature and climate.
