1. Selenian: - Rarity Percentage: 65% - Description: Selenian rocky planets are characterized by their abundant composition of silicate rocks and iron. They often have a thin atmosphere, if any, and their surfaces are dominated by craters caused by asteroid impacts. They have various geological formations like mountains, valleys, and plains. The most well-known example of a Selenian rocky planet is Earth's moon, Luna. 2. Enceladian: - Rarity Percentage: 20% - Description: Enceladian rocky planets are relatively rare and found in extreme environments. They have high surface temperatures and are often subject to intense volcanic activity, resulting in a surface covered with lava flows and volcanic peaks. These planets might have a tenuous atmosphere composed of volcanic gases such as sulfur dioxide or carbon dioxide. The temperature range for Enceladian rocky planets typically falls between 600 to 1200 Kelvin. 3. Adamean (Diamond): - Rarity Percentage: 10% - Description: Adamean rocky planets, also known as diamond worlds, are exceptionally rare and unique. They have a composition rich in carbon, specifically diamond (crystalline carbon). These planets may have formed in carbon-rich environments or experienced extreme pressure and temperatures to crystallize carbon into diamonds. Their surfaces would be covered in a shimmering layer of diamonds, making them a celestial marvel for astronomers and potential treasures for miners. 4. Mineralic (Crystal World): - Rarity Percentage: 5% - Description: Mineralic rocky planets, also referred to as crystal worlds, are uncommon and intriguing. These worlds have an extraordinary variety of crystalline formations covering their surfaces. The crystals can be formed from various minerals found on rocky planets, presenting a stunning visual spectacle. These unique formations could be the result of geological processes, such as volcanic activity or mineral-rich atmospheric conditions. Crystal worlds are prized for their aesthetic beauty and scientific value.

1. Venusian: - Rarity Percentage: 20% - Description: Venusian terrestrial planets are characterized by extreme heat and a thick, toxic atmosphere primarily composed of carbon dioxide. These planets often have a dense cloud cover, making their surface features difficult to observe directly. The high surface temperatures and atmospheric conditions create a hostile environment, with surface pressures that can crush spacecrafts. The Venusian class of terrestrial planets is relatively rare in the galaxy. 2. Garden (Continental): - Rarity Percentage: 60% - Description: Garden terrestrial planets, specifically the continental subtype, are relatively common and highly sought after for their potential to support life. These planets have a solid surface with large land masses or continents. They possess diverse environments, including mountains, valleys, forests, rivers, and lakes, making them reminiscent of Earth's continents. Garden terrestrial planets are characterized by moderate temperatures, a breathable atmosphere, and the presence of water, making them prime candidates for habitability. 3. Martian (Desert): - Rarity Percentage: 20% - Description: Martian terrestrial planets, often referred to as desert planets, are somewhat rare and share similarities with Mars. They have a thin atmosphere primarily composed of carbon dioxide, with little to no surface water. Martian planets are characterized by a predominantly desert-like landscape, with sandy or rocky terrain and occasional impact craters. These planets experience extreme temperature fluctuations and have a sparse biosphere, if any. The Martian class of terrestrial planets is known for its harsh conditions and limited resources.

1. Aquatic Garden Planet: - Temperature Kelvin Range: 273 - 373 Kelvin (0 - 100 degrees Celsius) - Description: Aquatic garden planets are characterized by a significant amount of surface water, with large oceans or seas covering a substantial portion of their landmasses. These planets have a moderate temperature range that allows for the existence of liquid water, making them potential habitats for a variety of aquatic species. These garden planets often have a diverse range of marine ecosystems and can support abundant marine life. 2. Methanic Garden Planet: - Temperature Kelvin Range: 70 - 110 Kelvin (-203 - -163 degrees Celsius) - Description: Methanic garden planets are unique and rare, characterized by low temperatures and an atmosphere predominantly composed of methane. These planets often have vast, frozen landscapes with icy plains and mountains. Despite the extreme cold, some forms of life, adapted to survive in methane-rich environments, can thrive on these planets. 3. Ammoniac Garden Planet: - Temperature Kelvin Range: 195 - 245 Kelvin (-78 - -28 degrees Celsius) - Description: Ammoniac garden planets are distinguished by their atmosphere rich in ammonia. They have a moderate to low temperature range and often exhibit unique geological features like ice mountains, geysers, and cryovolcanoes. While life as we know it may not survive in such environments, these planets can potentially harbor extremophiles or other forms of life adapted to high levels of ammonia. 4. Nitric Garden Planet: - Temperature Kelvin Range: 200 - 300 Kelvin (-73 - 27 degrees Celsius) - Description: Nitric garden planets have an atmosphere primarily composed of nitrogen compounds, such as nitrous oxide or nitrogen dioxide. They typically have a moderate temperature range and can support diverse ecosystems with plants and organisms adapted to the nitrogen-rich environment. These planets may also feature unique geological formations resulting from the interaction between nitrogen compounds and the planetary surface. 5. Neonic Garden Planet: - Temperature Kelvin Range: 220 - 320 Kelvin (-53 - 47 degrees Celsius) - Description: Neonic garden planets are characterized by a higher concentration of neon in their atmosphere, giving them a distinct appearance compared to other garden planets. The presence of neon can cause unique colorations and atmospheric phenomena. These planets often have diverse ecosystems and may support life forms adapted to the neon-rich environment. 6. Helic Garden Planet: - Temperature Kelvin Range: Variable depending on the specific environment - Description: Helic garden planets, also known as rogue planets, have a unique subclass characterized by the presence of seas or lakes consisting of liquid helium. These planets exist outside of a typical star system, drifting freely through space. Due to the extreme conditions and temperatures required for liquid helium, life as we know it may not be able to survive on helic garden planets. 7. Hydric Garden Planet: - Temperature Kelvin Range: 273 - 373 Kelvin (0 - 100 degrees Celsius) - Description: Hydric garden planets are abundant in surface water, similar to aquatic garden planets. However, hydric garden planets can also have a significant portion of their landmass covered in lush vegetation and terrestrial ecosystems. These planets are characterized by a moderate temperature range, making them suitable for a wide range of plant and animal life.
