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 factors determine how bright a star looks like from earth?
It's luminosity and it's distance from Earth
What two factors determine how bright a star looks from earth?
The two factors are temperature and luminosity based on the HR diagram. The stage of the star in its life cycle also plays a key part.
How do you determine a stars luminosity?
To determine a star's luminosity is from size and temperature.
What factor affects the luminosity of a star?
the size of a star
What factors affect the color of a star?
The temperature affects the color of a star.
How do size temperature and distance affect a star's magnitude or luminousity?
A star's real luminosity is proportional to the the square of its diameter, and more or less proportional to the fourth power of its absolute temperature. The star's apparent luminosity is proportional to its real luminosity. It is also inversely proportional to the square of the distance.
How is star luminosity measured?
A star's luminosity is measured according to the relevance to the sun. Basically for example, if a star is 8,300 degrees Celsius and has a luminosity of 0.001; the luminosity is compared to the sun.

How would an increase in mass affect the basic properties of a star?
As mass increases It increases the surface temperature , luminosity, and radius.
What factor affects the luminosity of a star?
the size of a star
What is a sentence with luminosity in it?
I was enthralled by the luminosity of the deep water jellyfish.
How do astronomers measure stellar luminosity?
The reference that astronomers use to compare the luminosity of other stars is the sun's luminosity. The luminosity is denoted in multiples of the sun's luminosity. For example, the luminosity of the star Sirius is 25 times the luminosity of the sun.
