What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
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 is luminosity also known as?
Luminosity is also known as brightness or radiance, and refers to the total amount of energy emitted by a star or other celestial object per unit time. It is a measure of the intrinsic brightness of an object.
What is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
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 is a star brightness called?
the brightness of a star is called it's magnitude
What is it called when brightness is how bright a star seems or looks?
The brightness of a star to an observer on Earth is called it's Apparent Magnitude. The intrinsic brightness of a star is known as it's Absolute Magnitude.
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
What does the absolute brightness of the star depend on?
the brightness of a star

What is the measure of the star's brightness?
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.

What measures the brightness of the star?
photographs use to measure the brightness of a star
A star's brightness is the brightness seen by humans on Earth. A star's brightness is its actual brightness and does not depend on where the star is viewed from.?
The brightness as seen from Earth is called the "apparent magnitude".The real brightness (defined as the apparent brightness, as seen from a standard distance) is called the "absolute magnitude".
What is the purpose of a star's brightness?
There is no purpose of a star's brightness. They just exist and shine.
What is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
What the measure of a stars brightness called?
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
