What is higher for closer stars?

If they had the same intrinsic brightness, then yes. However stars vary enormously in their intrisic brightness, so Deneb is distant, but one of the brightest stars in the Northern sky, whereas proxima centuri is the closest star to us, but so dim that it cannot be seen without a mid-size telescope.


How do you describe the stars of the first magnitude?

"First magnitude" usually means the brightest 21 stars, as seen from Earth. Another definition is stars with apparent magnitudes 0.5 to 1.5. This definition excludes the very brightest stars, like Sirius. They are the first stars that become visible after sunset and they all have names. Examples are Altair, Aldebaran, Capella, Spica, Antares, Fomalhaut, Deneb, Regulus, Sirius, etc. There can be confusion because First Magnitude stars are not stars with an "apparent magnitude" of exactly "one". They are just the brightest stars, but naturally their magnitudes are close to one.

Why is absolute magnitude of some stars greater than their apparent magnitude for stars?

The apparent magnitude is what we see, and this can be measured directly. The absolute magnitude must be calculated, mainly on the basis of (1) the apparent magnitude, and (2) the star's distance. So, to calculate the absolute magnitude, you must first know the star's distance.


What is alnilam's apparent magnitude?

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.

Are the brightest stars low or high magnitude?

The brightest stars have a low magnitude. Magnitude is measured on a logarithmic scale where lower numbers indicate brighter objects. The brightest star in the night sky, Sirius, has a magnitude of -1.46.

Which star is brighter one with a 6.3 magnitude or one with a magnitude of 1.4?

The smaller numbers indicate brighter stars. Also, a negative magnitude is even brighter than zero magnitude.

What is a second magnitude star?

A second magnitude star is a star that is relatively bright in the night sky, typically with an apparent visual magnitude between 1.5 and 2.5. These stars are easily visible to the naked eye and are brighter than third magnitude stars but dimmer than first magnitude stars.


What is the magnitude of the unamed star?

There are so many un-named stars it's impossible to give one of them a magnitude, they are all different.


What is the magnitude of Rigel?

Rigel has an apparent magnitude of around 0.12, making it one of the brightest stars in the sky. Its absolute magnitude, which measures intrinsic brightness, is around -7.0, indicating its high luminosity.

What is Saiph's apparent magnitude?

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.


What is the approximate absolute magnitude of Rigel?

The approximate absolute magnitude of Rigel is about -7.0. This makes it one of the brightest stars in the night sky.


What is the stellar magnitude of Lyra?

'Lyra' is a constellation ... a collection of stars ... and each one has a different magnitude. The brightest star in Lyra is 'Vega'. Vega was actually chosen as the standard for the magnitude measurements of all stars, and its brightness was originally defined as Zero Magnitude. Naturally, astronomical instruments have gotten better since then, and Vega is now listed as having a magnitude of 0.03 .
