Now about the exoplanets being rendered on the SSC files or about exoplanets period, the claimed planet around Barnard's star has been disputed after the radial velocity signal disappeared in the newer data:https://www.forbes.com/sites/brucedorminey/2021/05/18/astronomers-nix-idea-of-super-earth-around-barnards-star/?sh=421a9ef6842a
Therefore in the next Celestia Origin update, have Barnard b and c removed.
This goes to show us how hard it technically is to find and confirm planets or anything of such anywhere outside our Solar System even with all the technology we have.
Planet hunting appears easy to us, but the scientists, telescopes and their data are constantly working hard and inspecting.Added after 6 hours 38 minutes:
And about stars like Westerlund 1-26 (which's included in the top 10 largest stars file in the special stars folder), Westerlund 1-26's radius has been calculated to be 1165 to 1221 Sol radii whereas SIMBAD at its time corresponded the radius to 1530 to 1580 x Sol's based on based on effective temperatures of 3450 and 3660 K for M stars of such.
