List three factors that control the apparent brightness of a star as seen from earth?
Three factors that affect a star's brightness are the star's distance from earth, its age and its luminosity. The farther the star is from earth, the less bright it appears. As a star increases in age, its brightness also increases. Its brightness also depends on its luminosity, which is the amount of energy the star emits per second.
What three things affect the apparent magnitude of a star?
1: The size of the planet.2: The planet's distance from the Sun.3: The "albedo" of the planet (the percentage of the Sun's light it reflects).If you mean how bright the planet appears to us on Earth, then the distance from Earth is obviously very important.
Which factor does not affect the apparent brightness of a star?
How old a star is.
What might change depending on the distance to a star?
Its apparent brightness, as well as the star's gravitational field.
What factor affects the absolute brightness of a star?
Energy output, as absolute brightness (magnitude) is taken at a standard distance of 10 parsecs.
What 3 factors affect how bright a star appears from earth?
The 3 factors that affect a star's brightness as viewed from earth, are: The star's age, distance from earth, and actual magnitude (scale a star's brightness is measured in).

What two factor affect a stars apparent brightness?
Two factors that affect a star's apparent brightness are: 1.) The distance between the Earth and the star 2.) The absolute magnitude (the actual brightness) of the star Hope that helps :P
What are the factors that affect the brightness of the star?
Distance and intervenng or close celestial bodies
What are the factors that affect the brightness of star?
Distance and intervenng or close celestial bodies
What are the factors that may affect the brightness of star?
Distance and intervenng or close celestial bodies
What factors determine a stars brightness as seen from earth?
Distance from Earth, size of star, and temperature of star.
What factors determine a stars brightness seen from earth?
Distance from Earth, size of star, and temperature of star.

Is star colour caused by the distance star from eartth?
No. Star color is caused by factors such as size and temperature. However, apparent magnitude (brightness) IS partially caused by distance.
What terms takes into consideration the brightness of a star but ignores the differences that distance can make?
"Apparent magnitude" is the star's brightness after the effects of distance. "Absolute magnitude" is the star's brightness at a standard distance.
What do star's brightness depend on?
it depends upon 3 factors,1-the distance from the earth, 2-size of star and 3-age of the star.
