What is it called when a star suddenly increases in brightness?
A nova is a star that suddenly increases in brightness.
What is the brightness of a star measured on a scale called?
apparent magnatude
What is the stars intrinsic brightness called?
The intrinsic brightness of a star is called its absolute magnitude. This is a measure of how bright a star would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth.
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 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.
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 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 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".
What is it called when a star suddenly increases in brightness?
A nova is a star that suddenly increases in 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 as if it were a standard distance is called?
Absolute Brightness .
The actual brightness of a star is called?
magnitude
What is called to the brightness of a star?
the moon light
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 the brightness of a star as it appears called?
it's luminosity
What do you call the brightness of a star?
its called the magnitude dumb *ss
