Light takes only 4.24 years to reach us from Proxima Centauri. "Proxima hosts two exoplanets: a rocky but likely airless world dubbed Proxima Centauri b, with a mass of about 1.27 Earths and an orbital period of just 11 days, and Proxima Centauri c, a world probably around the size of Neptune." Proxima Centauri is 1.3 pc so a telescope with one arcsecond resolution, sees 1.3 au diameter size. When Proxima Centauri b was first discovered, many scientists had high hopes for it to inhabit living organisms. The authors detail . Such stars have different interior structures than our sun, so they are not expected to show magnetic activity cycles. In 2015, NASA's New Horizons probe Proxima Centauri. March 23, 2022 4:11pm. The question then becomes whether soon to be flown technology like the James Webb Space Telescope could detect artificial lights if they were present at Proxima b. July 6, 2014. This star is a red dwarf that forms a visual double with Alpha Centauri AB. One group of scientists, though, is hoping to find an Earthlike planet in our own backyard. It's star is a red dwarf that is much smaller than our Sun. A giant flare has erupted from nearby star Proxima Centauri that is 100 times more powerful than any flare our sun has ever released. .

Tabor and Loeb use recent work on Proxima Centauri c's inclination (citation below) to ballpark an orbital inclination for the inner world. The idea of having time critical observations in the UV with large scopes seems to be a losing proposition, but with the many smaller 1/2 meter to 1 meter observatories around the southern world this would still be easy to do!!
