Webb2 feb. 2024 · From the Alpha Centauri system's distance of 4.4 light-years, the Sun shines at magnitude +0.5, nearly as bright as Alpha Centauri (magnitude 0.0) appears in Earth's sky. Observers there would see it as … WebbFrom α Centauri, the sun would have an apparent magnitude of 0.5, about like Betelguese or Procyon from Earth. If you want to make this calculation for any star, use the formula 4.8 + 5 * ((log10 (d/3.26))-1) where d is the distance in ly. To calculate for other stars, replace the sun's absolute magnitude 4.8 with the star's. secrets temple
