What are two factors that determine the brightness of a star?
distance from the sun and the age of the star
What are the two factors that determine how bright a star looks from earth?
The two factors that determine how bright a star looks from Earth are its intrinsic brightness, or luminosity, and its distance from Earth. Stars that are more luminous will appear brighter, while stars that are closer to Earth will also appear brighter.
How can stars have different absolute brightness?
Stars can have different absolute brightness due to variations in their size, temperature, and distance from Earth. Larger stars have more surface area to emit light, hotter stars emit more intense light, and stars that are closer appear brighter. These factors contribute to the variations in absolute brightness among different stars.
Do stars have the same brightness and sizes?
No. Stars vary greatly in size and brightness.
What two factors determine how bright a star looks like from earth?
The two factors that determine how bright a star appears from Earth are its intrinsic brightness (or luminosity) and its distance from Earth. Intrinsic brightness refers to the amount of light a star emits, while distance affects how much of that light reaches us. Closer, more luminous stars appear brighter in the sky.

What factors determine a stars brightness seen from earth?
Distance from Earth, size of star, and temperature of star.
What factors determine a stars brightness as 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.

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.
