A nova is a star that suddenly increases in brightness.
List three factors that control the apparent brightness of a star as seen from earth?
Three factors that affect a star's brightness are the star's distance from earth, its age and its luminosity. The farther the star is from earth, the less bright it appears. As a star increases in age, its brightness also increases. Its brightness also depends on its luminosity, which is the amount of energy the star emits per second.
Which factor does not affect the apparent brightness of a star?
How old a star is.
Which star has the greatest brightness?
Sirius.
What color is markab?
the color of markab (most oftenly called pegasus) varys with the months and seasons. absolute brightness of the star appears to blue.
Why a stars color and brightness is important?

What type of star is Gomeisa?

What is the measure of the star's brightness?

What color of the star is the brightest?
The hottest stars are blue or blue-white. Brightness is a different matter, and is not strictly related to color.
What are characteristics used to classify a star?

How is the brightness of a star related to its distance from the sun?
the color of the sun sun depends on its surface temperature
What are the 7 ways a star can be classified?
mass, size, brightness, color, temperature, composition, and age
What relationship is shown on the HR diagram?
