What is a star's level of brightness as viewed by the unaided?
A star's brightness as viewed by the unaided eye is measured using a scale called apparent magnitude. This scale quantifies how bright a star appears from Earth, with lower numbers indicating brighter stars. For example, a star with an apparent magnitude of 1 is brighter than one with a magnitude of 6, which is at the limit of what the average human eye can see under ideal conditions. Factors influencing a star's apparent brightness include its intrinsic luminosity, distance from Earth, and any interstellar material that may dim its light.
What is it called when a star suddenly increases in brightness?
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?
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.
What is the apparent brightness of a star as represented by a number on a logarithmic scale?
The apparent brightness of a star is represented by its apparent magnitude, which is a logarithmic scale used to measure the brightness of celestial objects as seen from Earth. The lower the apparent magnitude number, the brighter the star appears in the sky. Each increase of one magnitude corresponds to a brightness factor of 2.5.
A star brightness is called?
Apparent magnitude.
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 is the brightness of a star measurable by a scale called?
It is called the magnitude scale. It is a log scale.
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.
What is it called when the brightness of a star is measurable on a scale?
Star brightness is defined in terms of apparent magnitude, which is how bright the star appears from Earth. Star brightness is also defined by absolute magnitude, which is how bright a star appears at the standard distance of 36.2 light years. Luminosity is also a way that a star's light is measured.
What is brightness of a star measurable on a scale is called .?

What is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
What term is used to describe a star's brightness?
It is called Vmag. This is the visual magnitude of the object. Visual magnitude is a scale used by astronomers to measure the brightness of a star or other celestial object. Visual magnitude measures only the visible light from the object. The lower the V-MAG the brighter the star. You can go to http://seasky.org/pictures/sky7b14.html to learn more.

What does measurement of the brightness of a star call?
Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
How is stars brightness measured from earth?
Astronomers use a special term to talk about the brightness of stars. The term is "magnitude". The magnitude scale was invented by the ancient Greeksaround 150 B.C. The Greeks put the stars they could see into six groups. They put the brightest stars into group 1, and called them magnitude 1 stars. Stars that they could barely see were put into group 6. So, in the magnitude scale, bright stars have lower numbers.
What is a star brightness called?
the brightness of a star is called it's magnitude
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".
