This is my interpretation of the data available for this system's planets. The planet's sizes are to scale. I took inspiration from the already exisiting artistic visualizations and created my own in Blender. Happy to hear your thoughts!
My take on the appearance of LHS 1140 b, an Exoplanet 48.8 lightyears away suggested to have an atmosphere by recent research. With 5.6 times the mass of the Earth and 1.73 Earth radii it is significantly larger and way more massive. Since we know its density of 5.9 g/cm³ which is higher than Earth's mean density of 5.5 g/cm³ we can infer that it has less water by composition, because more water would mean a lower density. Therefore my interpretation of LHS 1140 b has less surface water, an atmosphere, clouds (because if there's liquid water, there's clouds). Hope you like my illustration.
