The brightness and color of a star are related to its temperature and size. Hotter stars appear blue or white and are brighter, while cooler stars appear red or orange and are dimmer. The brightness of a star can also vary based on its distance from Earth.
A star's color tells us it's temperature, and indirectly, can tell us a lot about it's size. It's absolute brightness (as opposed to it's apparent brightness) also helps us define the star.
An apparent brightness is the brightness of a star as measured by an observer.
A star's temperature is indicated by its color, with hotter stars appearing blue and cooler stars appearing red. Brightness is measured using the star's apparent magnitude, with higher magnitudes representing dimmer stars and lower magnitudes representing brighter stars.
The color of a star indicates its surface temperature. Blue stars are hotter, while red stars are cooler. This temperature affects the star's brightness and behavior.
the color of markab (most oftenly called pegasus) varys with the months and seasons. absolute brightness of the star appears to blue.
The temperature of a star is indicated by its color, with blue stars being hotter than red stars. The brightness of a star is indicated by its apparent magnitude, with lower numbers representing brighter stars.
A star's color tells us it's temperature, and indirectly, can tell us a lot about it's size. It's absolute brightness (as opposed to it's apparent brightness) also helps us define the star.
The apparent brightness of a star is primarily affected by its intrinsic luminosity, distance from Earth, and any interstellar material that may dim its light. However, the color of the star does not directly affect its apparent brightness; it relates more to the star's temperature and stage of life rather than how bright it appears from our perspective. Thus, while color can indicate other properties of the star, it does not influence its apparent brightness.
its color does determine the temperature of star.
the brightness of a star
The hottest stars are blue or blue-white. Brightness is a different matter, and is not strictly related to color.
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
you classify stars by color, temperature, size, composition, and brightness.
the color of the sun sun depends on its surface temperature
The Hertzsprung-Russel diagram shows brightness versus color (the color reflects the star's temperature).
photographs use to measure the brightness of a star
A main sequence star's temperature is most closely related to its color and brightness.
