The apparent magnitude of Mercury varies because its brightness changes as it moves in its orbit about the sun. And the earth, from which we view Mercury and make a determination as regards it apparent magnitude, moves as well. It varies from -1.9 to 5.5 as we see it. (Some sources hold a -2.0 as a lower limit.) A link can be found below.
The apparent magnitude is 2.4
No, which means that Rigel appears brighter.
Apparent magnitude is 0.77 Absolute magnitude is 2.21Wikipedia lists its visual magnitude as 0.77.
The apparent magnitude is 4.5821
Saiph, a star in the constellation of Orion, has an apparent magnitude of around 2.09. It is one of the brighter stars in the constellation and can be seen with the naked eye.
Negative numbers are brighter. Our Sun has an apparent magnitude of -26.73, the Moon around -12. Sirius on the other hand has an apparent magnitude of -1.46, whereas apparent magnitude of Pluto's smallest moons Hydra and Nix is 23.
Antares Absolute and Apparent Magnitude Absolute Magnitude~ -5.2 Apparent Magnitude~ +0.60
The apparent magnitude of Neptune is 7.8
Vega has an apparent magnitude of 0.03.
The two types are apparent magnitude, the magnitude of a star as it appears to us, and absolute magnitude, which is what a star's apparent magnitude would be at a standard distance of ten parsecs.
The apparent magnitude of the Cartwheel Galaxy is 15.2
The apparent magnitude is 2.4
The apparent magnitude of a star is a measure of its brightness.
Apparent magnitude: How bright something looks to us. Absolute magnitude: How bright something really is - expressed as the apparent magnitude it would have at a standard distance.
Apparent magnitude is the measure of how bright a star appears as seen from Earth. This scale is based on a star's brightness perceived by human observers. The lower the apparent magnitude, the brighter the star appears.
it is an apparent magnitude of 1.74
The apparent magnitude of Vega is 0.03. The absolute magnitude is 0.58.
