Why do apparent brightness and absolute brightness differ according to astronomers? Which two parts of the Sun are in the solar atmosphere? Given that sunlight primarily has wavelengths ranging from around 0.4 micrometers to 2.4 micrometers, what is the intensity of sunlight reaching the Earth's ...

absolute magnitude - apparent magnitude of the star if it was located 10 parsecs from Earth apparent magnitude - a star's brightness as observed from Earth luminosity - total amount of energy emitted from a star per second parsec - distance measurement (3.3 light-years, 19.8 trillion miles,...
1. absolute brightness - the brightness a star would have if it were 10 parsecs from Earth. Looking for patterns If we plot a graph of luminosity against temperature for lots of stars we get a graph like this… HR DIAGRAM AND STAR SIZES!. So, we know how to measure the following prope...
