What is it called when a star suddenly increases in brightness?
A nova is a star that suddenly increases in brightness.
What is the original brightness of a star when it suddenly flares up to many times?
A star the size of our Sun or smaller is too small to become a "Nova", so we can expect that the original brightness of a "nova" star is probably brighter than the Sun; possibly a lot brighter.
A black what is formed from a exploded star?
If the star is larger than about 5 times the size of our Sun, a black hole can form from the core of the exploded star
List three factors that control the apparent brightness of a star as seen from earth?
Three factors that affect a star's brightness are the star's distance from earth, its age and its luminosity. The farther the star is from earth, the less bright it appears. As a star increases in age, its brightness also increases. Its brightness also depends on its luminosity, which is the amount of energy the star emits per second.
Which factor does not affect the apparent brightness of a star?
How old a star is.
What is it called when a star suddenly increases in brightness?
A nova is a star that suddenly increases in brightness.
A star that explodes temporarily increasing its brightest?
binary star
What is the original brightness of a star when it suddenly flares up to many times?
A star the size of our Sun or smaller is too small to become a "Nova", so we can expect that the original brightness of a "nova" star is probably brighter than the Sun; possibly a lot brighter.
What does the absolute brightness of the star depend on?
the brightness of a star
A star that explodes temporarily increasing it's brightness 100000 times or more?
Nova or supernova
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 difference between apparent brightness and absolute brightness?
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
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.
