TRAPPIST-1 b & c
This addon adds fictional textures for the two innermost planets orbiting the ultracool dwarf star TRAPPIST-1 to Celestia. Observations by the James Webb Space Telescope suggest that TRAPPIST-1 b lacks a significant atmosphere and has a low albedo, and that TRAPPIST-1 c similarly lacks a thick Venus-like atmosphere and may have a thin atmosphere or none.
