There are three factors, actually.
The star's size and temperature determine the absolute magnitude, or how bright the star really is.
Those two factors can be considered as one - the star's absolute magnitude.
The absolute magnitude combined with our distance from the star determines its apparent magnitude, or how bright the star appears to be from Earth.
So, a big, hot, super bright star very far away may have the same apparent magnitude as a small, cool star that's fairly close to the Earth.
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.
An apparent magnitude is a measure of how bright a star appears from Earth. The lower the apparent magnitude, the brighter the star appears in the night sky. Negative values indicate very bright stars, while positive values indicate fainter stars.
apparent magnitude is how bright a stars seems from earth. magnitude (i think called actual magnitude [I cant remember]) is how bright a star ACTUALLY is.Have a nice day.
No, which means that Rigel appears brighter.
The regulous star in Leo is known as Regulus. It has an apparent magnitude of 1.35, making it one of the brightest stars in the night sky.
The question is: Why is the apparent magnitude of some stars less than their absolute magnitude. Or: Why do some stars not look as bright as they really are ? The answer is: Because they're so far away from us.

The star's real magnitude (brightness), its distance from us, and anything in between (usually dust or gas) which might absorb part of the light.

The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
a star with apparent magnitude of 6 or less, the lesser the magnitude the brighter the star
Alnilam, the middle star in Orion's Belt, has an apparent magnitude of about 1.70, making it one of the brightest stars in the constellation of Orion.
Here is some information on three of Leo's stars - The three brightest stars in Leo the Lion are : Alpha Leonis or Regulus (the Lion's heart) with an apparent magnitude of 1.35, Beta Leonis or Denebola (the Lion's tail) with an apparent magnitude of 2.14 and Gamma Leonis or Algieba (where the Lion's mane meets his body) with an apparent magnitude of 1.98
