What are two factors that determine the brightness of a star?
distance from the sun and the age of the star
What are three physical factors that determine a star's brightness?
Three physical factors that determine a star's brightness are its temperature (hotter stars are brighter), size (larger stars are generally brighter), and distance from Earth (the closer a star is, the brighter it appears).
Which two factors determine the characteristics of a star?
The two main factors that determine the characteristics of a star are its mass and its age. The mass of a star determines its temperature, size, luminosity, and lifespan. A star's age affects its stage in its life cycle, such as whether it is a young, main-sequence star or an older red giant.
What 2 factors determine a star's apparent magnitude?
There are three factors, actually. The star's size and temperature determine the absolute magnitude, or how bright the star really is. Those two factors can be considered as one - the star's absolute magnitude. The absolute magnitude combined with our distance from the star determines its apparent magnitude, or how bright the star appears to be from Earth. So, a big, hot, super bright star very far away may have the same apparent magnitude as a small, cool star that's fairly close to the Earth.
What are the factors that affect the luminosity of the star?
Its size and temperature.
What factors determine how long a star lives?
the stars amount of mass
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 three factors determine the magnitude of star?
The apparent magnitude of a star is dependent on the star's size, temperature and distance from where it is observed. An absolute magnitude is determined by the same three factors, but the distance is fixed at 10 parsecs.

Its size and temperature.
What is the length of time a star should last?
it depends on the star. size can determine "lifespan", and other conditions as well.
What two factors determine the characteristics of a star?
It's mass and it's stage of life.
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.
