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).

How can you find the luminosity of a main sequence star?

You can find the luminosity of a main sequence star by measuring its apparent brightness and distance from Earth. Knowing the distance allows you to calculate the star's absolute brightness. Luminosity is then determined by comparing the absolute brightness of the star to that of the Sun, which has a known luminosity.

What are the factor that effects the brightness of a star?

The main factors that affect the brightness of a star include its size (larger stars are generally brighter), its temperature (hotter stars are brighter), and its distance from Earth (closer stars appear brighter). Other factors like the star's age and luminosity class can also impact its brightness.

What two factors determine how bright a star looks from earth?

The two factors that determine how bright a star looks from Earth are its intrinsic luminosity (actual brightness) and its distance from Earth. Stars that are more luminous and closer to Earth will appear brighter in the night sky.

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 does luminosity affect the CHZ?

Luminosity affects the habitable zone (CHZ) by determining the distance at which a planet would need to be from a star to have the right temperature for liquid water to exist on its surface. Stars with higher luminosity would have habitable zones farther out, while stars with lower luminosity would have habitable zones closer in. This means that the size and location of the CHZ around a star depend on its luminosity.

What is a Polaris star luminosity?

The main star in the Polaris system has a luminosity which is 2500 times that of the Sun.

List three factors that control the apparent brightness of a star as seen from earth?

The apparent brightness of a star is determined by its luminosity (true brightness), distance from Earth, and any intervening dust or gas that may absorb or scatter its light. These factors affect how bright a star appears in the night sky to an observer on Earth.

How can you find the luminosity of a main sequence star?

You can find the luminosity of a main sequence star by measuring its apparent brightness and distance from Earth. Knowing the distance allows you to calculate the star's absolute brightness.
