Aethon X

The planet Aethon X is a Temperate Marine Terra. It has high biodiversity but is younger compared to Earth, with up to 10 million species of animals. Aethon X is located 3.70 Gly from Earth. The planet experiences slightly shorter seasons that are more extreme than those on Earth, due to an average temperature of -10°C. Aethon X has green vegetation and a biodiversity structure very similar to Earth's, including trees, animals, and plants. Trees do not exceed 20 meters in height. The most widespread biomes on the planet are Steppes/Grasslands, Deserts, and Tundras, with forests, tropical rainforests, and savannas being rare. The planet orbits around K1.7V, which is estimated to run out of fuel in approximately 19 billion years.

== History ==
· ~7.312 billion years ago. Aethon X was formed around the star RS 0-5-21632-1227-2692-7-1721602-1970 A (Orange Dwarf)
· ~6.9-6.1 billion years ago, it is not known how water arrived on the planet. It is believed that water was delivered to the planet through comet impacts and volcanic outgassing.
· ~4.1 billion years ago, a supernova exploded near the planet, raising the temperature by up to 30°C.
· ~3.9 billion years ago, a large asteroid impact brought unicellular life to the planet, seeding it with the first microorganisms.
· ~2.5-1.4 billion years ago, the planet experienced its first warming period. This warming was caused by increased volcanic activity, which released significant amounts of greenhouse gases into the atmosphere, trapping heat and raising global temperatures.
· ~1.3 billion years ago, the first mass extinction occurred, and the exact cause remains unknown. It is hypothesized that this extinction event was triggered by severe environmental changes, such as a drastic shift in ocean chemistry and a decline in oxygen levels.
· ~621 million years ago. The emergence of multicellular life in the oceans
· ~410 million years ago, the second mass extinction occurred, resulting in the loss of up to 99% of all life on the planet. This extinction event was likely triggered by a dramatic increase in atmospheric CO2 levels and extensive volcanic activity, which led to severe climate changes and disrupted ecosystems.
· ~297 million years ago. The first organisms come to land.
· ~250-12 million years ago, the planet experienced an average temperature of 4-12°C, resembling Earth's climate during that period. It was home to up to 20 million species of animals. The planet was predominantly covered by tropical rainforests, savannas, and steppes/grasslands. The rich biodiversity supported complex food webs and diverse ecosystems. Seasonal changes were moderate, contributing to the stability of the habitats. Frequent weather patterns included heavy rainfall in forested regions and dry spells in grasslands, shaping the evolution of local flora and fauna.
· ~12 million years-23,000 years ago, the planet was in its second ice age, with an average temperature of -20°C. The dominant landscapes were tundras, taigas, and, occasionally, forests. During this time, the planet was home to up to 7 million different animal species. The cold climate led to adaptations in both flora and fauna, with many species evolving to survive in harsh conditions. Ice sheets and glaciers shaped the terrain, influencing migration patterns and species distribution.
· ~Today, Planet Aethon X is much colder than Earth. Currently, Aethon X is in a mild ice age that will last for another 2 million years. The dominant biomes on the planet are steppes/grasslands, deserts, tundras, and, occasionally, forests. Tropical rainforests and savannas are quite rare. The planet has fewer than 15 active volcanoes.
The atmosphere of Aethon X is thin, which contributes to its lower temperatures. Seasonal variations are minimal, with prolonged periods of cold. The planet's landscape is characterized by vast, open plains and rugged terrain. Despite the harsh conditions, a diverse range of hardy plant and animal species has adapted to the environment.
· The future of Planet Aethon X is quite promising. The planet will remain habitable for another 3.8 billion years. In approximately 2.5 million years, a warm period will begin, during which tropical rainforests will become the dominant biome. This warm period is expected to last for up to 980 million years.
