1. Selenian: Selenian planets are rocky planets similar to Earth's Moon, known as "selenites." They have a solid surface and are characterized by stark landscapes with numerous craters. Selenian planets may have relatively thin atmospheres or may lack an atmosphere altogether. The rarity percentage for Selenian planets can be shown in a pie chart as follows: - Selenian: 50% - Enceladusian: 25% - Adamean: Diamond: 15% - Mineralic: Iridescent crystal world: 10% 2. Enceladusian: Enceladusian planets are characterized by their icy crusts and subsurface oceans. They are named after Saturn's moon Enceladus, which exhibits similar features. These rocky planets have a temperature range within which they maintain liquid water beneath their icy surfaces. The temperature range for Enceladusian planets can vary, but for this example, let's consider it to be within the range of 200 to 273 Kelvin. 3. Adamean (Diamond): Adamean planets are extremely rare and are composed primarily of carbon-based compounds, such as diamonds. These planets have high-pressure environments that allow for the formation of diamond mountains and structures. The rarity percentage for Adamean (Diamond) planets can be shown in a pie chart as: - Selenian: 50% - Enceladusian: 25% - Adamean: Diamond: 15% - Mineralic: Iridescent crystal world: 10% 4. Mineralic (Iridescent Crystal World): Mineralic planets are known for their dazzling landscapes made up of iridescent crystals. These crystals reflect and refract light, resulting in stunning displays of colors. Mineralic planets are relatively uncommon and are seen as rare gems in the universe. The rarity percentage for Mineralic (Iridescent Crystal World) planets can be shown in a pie chart as: - Selenian: 50% - Enceladusian: 25% - Adamean: Diamond: 15% - Mineralic: Iridescent crystal world: 10%
