A star brightness is called?
Apparent magnitude.
How are the brightness and temperature related?
brightness and temperature are both related because brightness is actually tempature. However the system has become more refined. Instead of just looking at the star and determining magnitude one or magnitude two, an astronomer measures the brightness of the star using a device called a photometer. The photometer counts the number of photons coming from the star. This photon count is then compared to the photon count from a star whose magnitude is known. An accurate magnitude can then be calculated.
How bright a star appears as seen earth is called?
Apparent magnitude is the measure of how bright a star appears as seen from Earth. This scale is based on a star's brightness perceived by human observers. The lower the apparent magnitude, the brighter the star appears.
What is the difference between a twelfth magnitude and fifteenth magnitude star?
The main difference is brightness: a twelfth magnitude star is brighter than a fifteenth magnitude star. Magnitude is a logarithmic scale, so each step in magnitude represents a difference in brightness of about 2.5 times. This means a twelfth magnitude star is approximately 12.5 times brighter than a fifteenth magnitude star.
Is a high magnitude star more dense than a low magnitude star?
Magnitude is a measure of brightness, there is no relationship with density.
What is a star brightness called?
the brightness of a star is called it's 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 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 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 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.
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".
A star brightness is called?
Apparent magnitude.
The actual brightness of a star is called?
magnitude
What is star's magnitude?
The magnitude is the brightness of the star.
Name for How bright a star is from the earth?
The brightness of a star is called visual magnitude. The lower the visual magnitude is the brighter the star is.
What do you call the brightness of a star?
its called the magnitude dumb *ss
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.
