APPARENT MAGNITUDE As seen from ABSOLUTE MAGNITUDE ) As seen from? I1 (Proxima Centauri) 15 (Proxima Centauri) 6i 4 (4.8-The Sun) I (1.09-Pollux) (1.16 = Pollux) 0 (0.45-Betelgeuse -4 -4 -26 (The Sun) 5 (-5.14= Betelgeuse) 27) Whar variable of apparent brightness is eliminated when discussing absolu brightness? For apparent magnitude, what is the limiting magnitude of the human eye in dark un-light polluted skies? What do you need to do to observe dimmer objects? 28)Explanation / Answer
25. The apparent magnitude of the sun is -26.74 and its absolute magnitude is 4.83. Apparent magnitude is the apparent magnitude at a distance of 10 parsecs. With respect to the apparent magnitude, the sun is the brightest object.
26. Apparent Magnitude as seen from the Earth by an observor.
Absolute magnitude as seen from a distance of 10 parsecs.
a. Distance of Pollux from Earth is 33.72 light years.
b. Distance of Betelguese from Earth is 642.5 light years.
c. Distance of Proxima Centauri from Earth is 4.243 light years.
27. The apparent magnitude is a function of how much bright a star may appear when viewed from an observor on Earth.
