How could a smaller star have a greater magitude than a larger star?
A smaller star can appear brighter from Earth (apparent magnitude) if it is much closer. The absolute magnitude (brightness compared side by side at fixed distance) can also be higher in a smaller star if it is much hotter and more massive. A smaller star can be much heavier (more dense) and hotter than a large star, especially the huge red giants nearing the end of their life (which have a very low density).
How bright a star appears as seen earth is called?
Apparent magnitude is the measure of how bright a star appears as seen from Earth. This scale is based on a star's brightness perceived by human observers. The lower the apparent magnitude, the brighter the star appears.
How can i compare and contrast the apparent and absolute magnitude of stars?
Apparent magnitude measures how bright a star appears from Earth, influenced by its distance and intrinsic brightness, while absolute magnitude reflects a star's true brightness at a standard distance of 10 parsecs. To compare the two, consider that a star may have a high apparent magnitude (appearing bright) if it's relatively close, even if it has a low absolute magnitude (inherently dimmer). Conversely, a distant star with a high absolute magnitude may appear faint from Earth. Analyzing both magnitudes helps astronomers understand a star's distance, size, and luminosity.
How much brighter is a magnitude 2 star than a magnitude 4 star?
A magnitude 2 star is 2.5 times brighter than a magnitude 4 star because each difference in magnitude corresponds to a difference in brightness of approximately 2.5 times.
What is difference in a star's apparent magnitude and absolute magnitude caused by?
How far away the star is.
What factor is not used to determine a star's apparent magnitude?
how dense the star is

What kind of star has an absolute magnitude of 10 and a surface temperature of 20000 K?
This star would be a white dwarf, as it has a high surface temperature of 20000 K but a low absolute magnitude of 10. White dwarfs are small, dense remnants of low to medium mass stars that have exhausted their nuclear fuel and collapsed.
What is a star brightness called?
the brightness of a star is called it's magnitude
Star A is a first magnitude star. Star B is a sixth magnitude star. Which star is brighter and by how much?
A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.
What is star's magnitude?
The magnitude is the brightness of the star.
What are the small dense remains of a high mass star?
The small dense remains of a high mass star are either a neutron star or a black hole, depending on the mass of the original star. Neutron stars are formed from the core collapse of a massive star and are incredibly dense, composed mainly of neutrons. Black holes are formed when the core collapse results in a singularity with infinite density and a gravitational pull so strong that not even light can escape.
How bright a star appears as seen earth is called?
Apparent magnitude is the measure of how bright a star appears as seen from Earth. This scale is based on a star's brightness perceived by human observers. The lower the apparent magnitude, the brighter the star appears.
What is the small dense remains of a high -mass star?
white dwarf
What is small dense remains of a high mass star?
white dwarf
What part of a star is called magnitude?
Magnitude refers to the brightness of a star. There are two main types: apparent magnitude, which is how bright a star appears from Earth, and absolute magnitude, which measures a star's intrinsic brightness.
How can i compare and contrast the apparent and absolute magnitude of stars?
Apparent magnitude measures how bright a star appears from Earth, influenced by its distance and intrinsic brightness, while absolute magnitude reflects a star's true brightness at a standard distance of 10 parsecs.
