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.
Which factor does not affect the apparent brightness of a star?
How old a star is.
A star brightness is called?
Apparent magnitude.
What factor does not affect the apparent brightness of a star?
The apparent brightness of a star is primarily affected by its intrinsic luminosity, distance from Earth, and any interstellar material that may dim its light. However, the color of the star does not directly affect its apparent brightness; it relates more to the star's temperature and stage of life rather than how bright it appears from our perspective. Thus, while color can indicate other properties of the star, it does not influence its apparent brightness.
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.
What is it called when a star suddenly increases in brightness?
A nova is a star that suddenly increases in brightness.
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 does the magnitude of a star measure?
The brightness of a star.
What is star's magnitude?
The magnitude is the brightness of the star.
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.
