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 of Venus ranges from -4.9 (full) to -3.8 (crescent).
The apparent magnitude of Jupiter is 1.6 to -2.6 depending on where it is at.
Venus has an apparent magnitude of:
See related question for apparent magnitude.
Neptune's apparent magnitude is about 8, making it much to faint to see without a telescope.
If you mean the planet Mars, that's +1.6 to -3.0. The fairly large variation is mainly due to the varying distance from Earth.
The apparent magnitude of Venus is -4.9 (brightest @crescent) and -3.8 (full)
-2.5 to -12.9
-12.9 is a full moon
it has an apparent magnitude of 2.1
The apparent magnitude is 2.4
Apparent magnitude is 0.77 Absolute magnitude is 2.21Wikipedia lists its visual magnitude as 0.77.
The apparent magnitude is 4.5821
The Sun with an apparent magnitude of -26.74. Followed by Sirius with an apparent magnitude of -1.46
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
it has an apparent magnitude of 2.1
The apparent magnitude of Neptune is 7.8
Vega has an apparent magnitude of 0.03.
Apparent magnitude is the brightness of an object as seen from Earth without any atmosphere.
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 of a star is a measure of its brightness.
The apparent magnitude is 2.4
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.
it is an apparent magnitude of 1.74
