CHATBOT: Creating a star system generator with a variety of rocky planets can add depth and immersion to your game. The size of a rocky planet can suggest a lot about its geological history, potential for an atmosphere, and possibility of life. For your game, we could categorize rocky planets based on real astronomical observations and theoretical models, and then assign rarity percentages to these categories. Below is a suggested setup: ### Rocky Planet Radius Range and Rarity 1. **Mini-Worlds (Ultra Common)**: - Radius Range: 1000 - 3000 km - Rarity: 25% - Examples: Mercury-like planets, large moons 2. **Terrestrial Planets (Common)**: - Radius Range: 3000 - 5000 km - Rarity: 30% - Examples: Mars to slightly smaller than Earth 3. **Super-Earths (Uncommon)**: - Radius Range: 5000 - 7000 km - Rarity: 20% - Examples: Larger than Earth but not so large that they start gathering thick hydrogen-helium atmospheres 4. **Mega-Earths (Rare)**: - Radius Range: 7000 - 9000 km - Rarity: 15% - Note: These planets are rare, they're significantly larger than Earth, leading to higher surface gravity; they're still rocky, though they may have significantly denser atmospheres. 5. **Iron Planets (Ultra Rare)**: - Radius Range: 2500 - 6000 km (with a higher density than typical terrestrial planets) - Rarity: 10% - Note: These planets have lost most of their mantle through collisions or other mechanisms, leading to a higher core-to-mantle ratio. This category includes planets that might otherwise fit into categories 1 and 2 but are significantly denser due to their composition. ### Implementation: Implementing these categories and rarities in your game would not only diversify the types of planets players can discover but also add a layer of realism and excitement to exploration. The actual distribution can be tweaked based on the narrative and gameplay needs of your game, as well as feedback from your player base. Please note, these figures are based on a mix of observational data from exoplanet discoveries and theoretical models of planet formation and evolution. Adjustments might be necessary to best fit the lore and physics engine of your game.
