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 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.
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 two major factors determine the size of a star?
The two major factors that determine the size of a star are its mass and its age. A star's mass dictates how much material there is to form the star, while its age influences the stage of its life cycle, which in turn affects its size.
What part of a star is called magnitude?
Magnitude refers to the brightness of a star. There are two main types: apparent magnitude, which is how bright a star appears from Earth, and absolute magnitude, which measures a star's intrinsic brightness.

What two factor affect a stars apparent brightness?
Two factors that affect a star's apparent brightness are: 1.) The distance between the Earth and the star 2.) The absolute magnitude (the actual brightness) of the star Hope that helps :P

Looking at the H-R diagram what 2 factors determine the brightness of a star?
The H-R diagram graphs total brightness versus surface temperature (related to color); by itself, it doesn't tell you where those two things come from.The brightness of a star depends on its mass, and on where it is in its development history.
What two major factors determine the size of a star?
The two major factors that determine the size of a star are its mass and its age. A star's mass dictates how much material there is to form the star, while its age influences the stage of its life cycle, which in turn affects its size.
What two factors determine the characteristics of a star?
It's mass and it's stage of life.
What part of a star is called magnitude?
Magnitude refers to the brightness of a star. There are two main types: apparent magnitude, which is how bright a star appears from Earth, and absolute magnitude, which measures a star's intrinsic brightness.
What two characteristics of a star determine its luminosity?
The luminosity of a star is primarily determined by its temperature and size (or radius). A hotter star emits more energy than a cooler star, while a larger star has a greater surface area from which to radiate energy. Together, these factors influence the total amount of light and heat the star produces, defining its overall brightness as observed from a distance.
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 two things must an astronomers find out in order to calculate a star's absolute brightness?
It's distance from Earth and the star's actual brightness
A basic observation of a star is how bright it appears this brightness is known as the stars?
The brightness of a star as observed from Earth is known as its apparent magnitude. This measurement reflects how bright the star appears in the sky, which can be influenced by factors such as distance, size, and luminosity. In contrast, a star's intrinsic brightness, or true luminosity, is referred to as its absolute magnitude. These two concepts help astronomers understand both the distance to stars and their actual energy output.
