Magnitude
A measure of brightness of a celestial object as observed from Earth.
Magnitude m=6 star
A star with a brightness level defined by its apparent magnitude of 6.
Magnitude m=8 star
A star with a brightness level defined by its apparent magnitude of 8.
Brightness comparison
A magnitude difference of 2 corresponds to a brightness factor of 2.5.
Artificial star
A light source created to simulate a star's appearance from Earth.
Magnitude of light source
The measure of brightness resulting from a combination of light sources.
Twofold brightness increase
A star that appears twice as bright has a magnitude that is less than the original.
Magnitude calculation
When adding magnitudes, a difference of 5 means a brightness factor of 100.
