Eurybia

Eurybia or RS 8513-1842-6-199734-454 4 - is the fourth planet from the star RS 8513-1842-6-199734-454(Yellow dwarf). The planet is a temperate marine terra. Eurybia can be described as a slightly cool oceanic planet dominated by islands of volcanic origin.

## History

* Eurybia formed 7.8 billion years ago
* ~7.6 billion years ago. The temperature of the planet has cooled
* ~7.6-4.2 billion years ago. During this epoch, Eurybia was an oceanic terra on which great storms occurred. The oceans were very unstable
* ~7.3 billion years ago. The emergence of unicellular life
* ~5.9 billion years ago. The emergence of multicellular life
* ~4.2 billion years ago. Geological and volcanic activity. The appearance of many islands and a small increase in CO2. The climate has become less hostile
* ~2.8 billion years ago. The first organisms came to land
* ~2.1 billion years ago. The age of the ruins at the bottom of the ocean
* ~570 million years ago. The extinction is probably associated with the fall of the asteroid. Many islands sank and about 50% of all flora and fauna died.
* Today - The planet has a rather calm climate. There are many islands of volcanic origin, where flora grows only off the coast. The relief is almost flat.

## Biosphere

Each island has many unique species. Animals on the planet are lower than Earth, but faster. For the most part, they look like ordinary animals from the Earth, such as roe deer. But their behavior is more complex and social. The flora is green in color and grows on small islands and in coastal areas of volcanoes. Forests and even jungles are widespread, despite the colder climate than on Earth. The marine flora and fauna is quite unusual, it lives only in shallow water, everything is lifeless at the depths and bottom

## Numerous ruins at the bottom

During the study of Eurybia, countless ruins were discovered that cover almost the entire bottom of the world's oceans. The study of "underwater cities" was very difficult, sometimes the depth was 13-14 kilometers. The ruins were in a very bad condition, time and water have changed them a lot. Thanks to radioisotope dating, it was possible to determine the age of the ruins at 2.1 billion years. Some scientists suggest that Eurybia was once covered by one huge city - Ecumenopolis, which sank. The study of the ruins continues, but certain valuable data have already been found, such as strange coordinates that lead to another part of the galaxy. We managed to calculate where the point is in coordinates, and it turned out to be another planet at a distance of 44 thousand light years, presumably also oceanic. This planet was named Tsovinar because its real name is unknown.

## Star system

There are 10 planets revolving around the star RS 8513-1842-6-199734-454, and besides Eurybia there is only one planet that has liquid on the surface ***RS 8513-1842-6-199734-454 8*** - frigid lacustrine aquaria. The oceans are made entirely of liquid nitrogen. This system also has a satellite that has life on it. ***RS 8513-1842-6-199734-454 7.4*** - cool airless miniaquaria. On this seemingly hostile satellite, an entire ecosystem of multicellular organisms has formed in the subglacial ocean. These animals take energy from geothermal sources. It is also confirmed that two planets in this system once had water. ***RS 8513-1842-6-199734-454 1*** and ***RS 8513-1842-6-199734-454 4*** are both hot planets where riverbeds have been found.
