The brightest stars were traditionally magnitude 1; the weakest that could still be seen with the naked eye, 6. This system has been formalized and refined; as a result, there are now not only magnitudes with decimals, but also negative magnitudes for the very brightest stars and planets. For example, Venus has a magnitude of approximately minus 4.

What star has the brightest apparent magnitude as seen from earth?
The brightest star as seen from Earth is the sun. The brightest star in the night sky is Sirius.
What is the magnitude of Enif?
Enif, also known as Epsilon Pegasi, is a supergiant star located in the constellation Pegasus. It has a visual magnitude that ranges between approximately 2.37 and 3.48, making it one of the brightest stars in the night sky.
Can you see Ceres at night with out a telescope?
No, except in rare optimal viewing conditions. Its brightest magnitude is 6.7, which is normally too dim for the unaided eye.
What is an example of apparent magnitude?
Apparent magnitude is a measure of how bright a celestial object appears from Earth. For example, the star Sirius, which is the brightest star in the night sky, has an apparent magnitude of about -1.46. This value indicates its brightness relative to other stars, with lower numbers representing brighter objects.
What is siriuss magnitude?
Sirius, the brightest star in the night sky, has an apparent magnitude of about -1.46. Its absolute magnitude is approximately +1.4. This extreme brightness is due to its proximity to Earth, as it is located about 8.6 light-years away. Sirius is actually a binary star system, consisting of Sirius A and Sirius B.
