(I'm on mobile, so sorry for bad formatting) So far I've designed two planets, and would like for them to orbit each other at a distance of roughly 1.25 million km (both planets would easily stay in the hz), the smaller being tidally locked. One has a radius of 6,371 km and a mass of ~4.776×10^(24) (the smaller, tidally locked planet), the other has a radius of 7,645 km and a mass of ~1.1002×10(25) (the larger planet). The estimated orbital period is 39 days 11 hours. The star is class KV, with .625 solar masses, and a luminosity of 0.16386 solar units. I'm wondering what the tidal forces of each planet would be, if it would be possible for life to develop on the larger planet, and if the smaller planet would be habitable even though it would have a relative day/night length of almost 40 earth days. If any other factors are needed for clarification please tell me and I'll edit the post.
