How do scientist determine the surface temperature of the stars?
brightness
What are the three main elements that determine a stars brightness from earth?
1) absolute brightness 2) distance 3) intervening dust
The light from stars are used to determine what?
The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
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.
What determines how bright stars are?
Size and temperature determine the brightness of stars.
How do scientist determine the surface temperature of the stars?

What are the factors that affect the brightness of stars?
Distance and intervenng or close celestial bodies
How can varble stars be used to determine the distance to globular clusters?
The idea is that CERTAIN TYPES of stars, including certain variable stars (such as Cepheids) have a known brightness; so if you observe their apparent brightness, you can calculate their distance.

What indicates stars of brightness and temperature?
The color of stars determines temperature. Red/brown stars are cooler, blue stars are hotter, and yellow stars are in between. Brightness also has some correlation with color. Both are based on many varying factors however.
What three things determine which stars you see in the sky?
Your place on the earth, The brightness of the star, Its distance.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
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
