that's an interesting system i hadn't heard of before. proxima will be the stepping stone to get to such systems further out.   if there is an oxygen atmosphere, the atmospheric composition and partial pressurs has to be just right for us to breathe it without getting sick. the pressure at sea level could be 2 atm, which is perfectly survivable, and the oxygen would have to make up about 10% of the atmospheric composition, as opposed to 21% like here on earth. that's assuming the rest of the atmosphere is an inert gas like nitrogen and not something like co2 which would make it toxic. there could also be a planet with an atmosphere only 21% as thick as earth's, but fully comprised of oxygen, and it would be survivable. it's interesting to think about.   kessler syndrome is fake news and a midwit talking point. niggers or pajeets will never be able to achieve interstellar travel, and if they do, we will be able to shoot their ships down before they come anywhere near our planets.   emperor barron trump of proxima centauri.
