What factor does not affect the apparent brightness of a 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.
Do star color indicates the absolute distance?
No, the color of a star does not directly indicate its absolute distance. Star color is related to its surface temperature, and stars of different temperatures can be located at varying distances from Earth. The brightness of a star, as measured by its apparent magnitude, is more indicative of its distance.
What is it called when a star suddenly increases in brightness?
A nova is a star that suddenly increases in brightness.
List three factors that control the apparent brightness of a star as seen from earth?
The apparent brightness of a star is determined by its luminosity (true brightness), distance from Earth, and any intervening dust or gas that may absorb or scatter its light. These factors affect how bright a star appears in the night sky to an observer on Earth.
Which factor does not affect the apparent brightness of a star?
How old a star is.
What is the main sequence star's temperature most closely related to?
A main sequence star's temperature is most closely related to its color and brightness.
What brightness color of star?
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.
What are the temperature and brightness of stars indicated by?
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.
What color is markab?
the color of markab (most oftenly called pegasus) varys with the months and seasons. absolute brightness of the star appears to blue.
Why a stars color and brightness is important?
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.

What is the most rarest color of a star?
The rarest color of a star is typically considered to be blue-violet. While most stars fall into the categories of red, yellow, or white, blue stars emit a high temperature of light and are much less common in the universe. They are often massive and have shorter lifespans, which contributes to their rarity. Additionally, the existence of blue-violet stars is limited, as they are typically found in specific environments like star-forming regions.
One way in which scientists can determine the surface temperature of a star is by its A. brightness. B. composition. C. color. D. mass.?
its color does determine the temperature of star.
What does the absolute brightness of the star depend on?
the brightness of a star
What color of the star is the brightest?
The hottest stars are blue or blue-white. Brightness is a different matter, and is not strictly related to color.
What is the measure of the star's brightness?
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.
What are characteristics used to classify a star?
you classify stars by color, temperature, size, composition, and brightness.
