List Notes: Apparent magnitude (also known as "visual magnitude") is the factor used to measure the brightness of any celestial body as seen from Earth. That brightness is then normalized to eliminate the atmosphere. The brighter the object the lower its apparent magnitude (for comparison the apparent magnitude of the Sun is -26.74).
