Aster and Liad

## Aster

(Used Rodrigos Mod)

Aster or RS 8513-3145-6-168538-628 7a - is the seventh planet from the star RS 8513-3145-6-168538-628. The planet is a warm marine super-Earth. A satellite marine terra Liad the size of Earth revolves around the planet.

ESI: 0.666

### History

* Aster, like Liad, is 8.1 billion years old. We don't know when Liad became Aster's satellite. But, a lot of evidence indicates that Liad was formerly a separate planet, which, through unknown circumstances, became a satellite of Aster.
* ~7.6 billion years ago. The planet cooled down, presumably, at that time the planet already had oceans
* ~6.9 billion years ago. Planet temperature ~140 °C. Surprisingly, over the next billions years, the temperature did not change much.
* ~4.3 billion years ago. The evolution and emergence of multicellular life at the bottom of the oceans, where there was a relatively acceptable temperature
* ~2.1 billion years ago. The first amphibians, they were very small and fast in order to spend as little time as possible on land. Such a huge time from the appearance of multicellular life to the first amphibians is most likely due to the extremely high temperature of the planet and arid, hellish landscapes and desert continents.
* ~1.7 billion years ago. The emergence of flora capable of withstanding such enormous temperatures on the surface of Aster. Over the next 500 million years, the continents became about 20% green. Flora has always been located in coastal zones, but over the course of millions of years it gradually developed and in the next hundreds of millions of years begins to grow deep into the continents.
* ~1.2 billion years ago. The emergence of burrowing species capable of withstanding high temperatures. These animals spent most of their lives underground.
* ~900 million years ago. The number of canals and tunnels dug by animals was already large. Half of the tunnels were already filled with water. This species, one might say, became the basis for the development of future life on the planet. Groundwater greatly helped plants move deep into the continents, the surface of the continents was about 70% green
* ~610 million years ago. Species that can withstand high surface temperatures for a very long time have appeared.
* ~370 million years ago. Burrowing species that live underground are extinct.
* ~179 million years ago. Flora was able to cover almost the entire surface of the continents. Aster, once a world with hellish deserts, has become a green planet, even though the temperature has not changed
* ~83 million years ago - Animals appeared capable of being on the surface all their lives.
* Today - There are quite a lot of lakes and rivers on the continents. They were formed by tunnels dug by animals hundreds of millions of years ago. Many of these canals still exist today. Life on the planet develops slowly due to the high surface temperature. Perhaps someday the time will come, and intelligent life will appear on Aster

### Biosphere

On Aster, animals are mostly small in size and have fast limbs. Some animals, when adverse conditions occur, may burrow into the ground, or try to dig through the remaining water tunnels. All this was left to them, from the now extinct burrowing species. The flora of the planet has a green color and sprouts almost everywhere, thanks to a long evolution and water canals. In the oceans, animals feel much better, at the bottom of the oceans there is a very active ecosystem.

### Planet suitability for colonization

Unfortunately, Aster has many conditions that prevent her from being colonized without difficulty. At a minimum, a person cannot survive with a temperature of +140 °C. There are spacesuits that allow you to withstand such temperatures for a short time. But, we do not have technologies that allow us to withstand such temperatures for a long time. Perhaps if try to lower the temperature of Aster, this will greatly change the planet in a favorable direction.

## Surface Conditions

### Atmosphere

* 69.7% N2
* 30.3% CO2

## Liad

Liad or RS 8513-3145-6-168538-628 7a - satellite of Aster. Liad is a cool marine terra.

ESI: 0.867

### History

* Liad was formed 8.1 billion years ago. Perhaps it was a separate planet.
* ~7.7 billion years ago. Approximate time when the satellite cooled down
* ~7.7-2.5 billion years ago. Liad was an ordinary desert terra like Mars. However, there were huge deposits of ice on the planet, and it is possible that after the planet formed, it had oceans for some time. The temperature of the planet during this period was about ~-100/-170 °C. The complete opposite of Aster.
* ~2.5-1.3 billion years ago. An increase in the temperature of Liad to -50 °C, perhaps it was in this era that Liad became a satellite of Aster
* 1.3 billion years ago - Today. The ice melted, and seas and oceans reappeared on the satellite The gradual warming of the planet continues to this day.

### "Vyunger Paradox" or "Paradox of Lifelessness"

These names were called the question asked by the scientist William Vyunger. The question is, "Why is there no life on Liad?". Pretty simple question, but difficult to answer. After all, Liad has all the conditions for life, all the more, with the help of asteroids, life from Aster could move to Liad, because nothing prevents this. Some offer a version that the planet has cooled relatively recently, and life has not yet had time to arise, while others simply say that this is a coincidence.

### Planet suitability for colonization

Surprisingly, Liad is more suitable for human colonization than on Aster. A temperature of ~-30 °C is relatively acceptable for colonies to develop without problems for a long time. Perhaps someday the first person will land on Liad and see a huge, eye-pleasing greenish planet - Aster.

## Star system

Both Aster and Liad revolve around the same star as the Sun - a yellow dwarf RS 8513-3145-6-168538-628. The star system is even more surprising and interested in a huge number of scientists. The star, in addition to Aster and Liad, has two more planets on which life is possible, and one more planet on which life already exists. *RS 8513-3145-6-168538-628 8* - Cold lacustrine subaquaria, which formed such an exotic biosphere that scientists have never seen. This planet is one of the most promising for study. *RS 8513-3145-6-168538-628 4* - Warm lacustrine terra, although the temperature of the planet is ~150-190 °C, there is every chance that there is or will be life. After all, on Aster, with a temperature of 140 ° C, the biosphere appeared. *RS 8513-3145-6-168538-628 5* - Temperate superoceanic aquaria. The temperature of the planet is ~30-40 °C. And it is quite possible that the appearance of life on this planet is only a matter of time. Also, the ocean floor consists of Ice VI, which is of interest to scientists, because before that Ice VI was created only in laboratories, and finding it in nature is of scientific value.
