A planet around either or B would see the other star as a very bright secondary. For example, an Earth-like planet at from (with a revolution period of 1.34 years) would get Sun-like illumination from its primary, and would appear 5.7–8.6 magnitudes dimmer (−21.0 to −18.2), 190–2,700 times dimmer than but still 150–2,100 times brighter than the full Moon. Conversely, an Earth-like planet at from (with a revolution period of 0.63 years) would get nearly Sun-like illumination from its primary, and would appear 4.6–7.3 magnitudes dimmer (−22.1 to −19.4), 70 to 840 times dimmer than but still 470–5,700 times brighter than the full Moon.
