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.


How does the light from flashlight that is shone from two differences model the apparent magnitude of two starts with the same absolute magnitude?

The light from a flashlight can be used to model the apparent magnitude of two stars with the same absolute magnitude by demonstrating how distance affects brightness. Just as a flashlight's light diminishes with distance, the apparent brightness of a star decreases as it moves farther away from an observer. If two stars have the same absolute magnitude but are at different distances, the one closer will appear brighter (higher apparent magnitude) than the one farther away. This relationship illustrates how apparent magnitude depends not only on intrinsic brightness but also on distance from the observer.


What system classifies stars according to its brightness?

The system that classifies stars according to their brightness is called the magnitude scale. This scale measures the apparent brightness of stars as seen from Earth, with lower numbers indicating brighter stars; for example, a star with a magnitude of 1 is brighter than one with a magnitude of 5. Additionally, the absolute magnitude scale measures the intrinsic brightness of stars at a standard distance of 10 parsecs. Together, these systems help astronomers categorize and compare stars based on their luminosity.

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.
