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.
How do scientist determine the surface temperature of the stars?
brightness
What is a stars apparent magnitude?
a stars brightness as seen from Earth
What is a stars brightness as if it were a standard distance?
Theres `Absolute Magnitude` which is the brightness of a star at a set distance. Then there is `Apparent Magnitude` which is the apparent brightness from earth, regardless of distance.
By simply looking at the sky at night Can you pick out stars that are hotter then the sun Cooler than the sun What do you look for Is the star brightness a clue?
Generally the red stars are colder, the blue stars are hotter.Apparent brightness has nothing to do with this. A bright-looking star may simply be nearer to Earth. It may also have a large surface area.Generally the red stars are colder, the blue stars are hotter.Apparent brightness has nothing to do with this.

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 three things determine which stars you see in the sky?
Your place on the earth, The brightness of the star, Its distance.

What determines how bright stars are?
Size and temperature determine the brightness of stars.
How do scientist determine the surface temperature of the stars?
brightness
What is a stars apparent magnitude?
a stars brightness as seen from Earth
What compares the brightness of stars as if they were the same distance from earth?
midorz
What the measure of a stars brightness called?
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.
How stars differ as to brightness?
every star has different elements in the atmosphere which absorbs the light
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.
Is it true that two stars that have the same brightness are the same distance from earth?
false
