How do scientists classify a star by size?
The scientists classify them by them color,there tempher,and by there light.
What is difference between apparent brightness and true brightness?
Apparent brightness: how bright an object - such as a star - looks to us. True brightness: how bright such an object really is. Defined as: how bright it would look at a standard distance.
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?
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.
Is it possible for two regular stars to have the same absolute magnitude but differ in apparent magnitude?
One dimmer star can be closer than a brighter star that is far away. Light flux decreases as the square of the distance. A star that is three times as far away will have to shine nine times brighter than the closer star (absolute magnitude) to appear to have the same magnitude (apparent magnitude). Because apparent magnitude is the brightness of a star, as seen from Earth, whereas absolute magnitude is the brightness of a star as seen from the same distance - about 32.6 light years away.
One way in which scientists can determine the surface temperature of a star is by its A. brightness. B. composition. C. color. D. mass.?
its color does determine the temperature of star.
What properties do scientists use to group stars?
Temp.,Size, Brightness, And How Many LightYears Away The Star Is.
What happens to the brightness of the star as you observe it from farther away?
The brightness of star will decrease as you observe it from farther away.
What happen to the brightness of a star as you observe it from farther away?
The brightness of star will decrease as you observe it from farther away.
The light from stars are used to determine what?
The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.
What are two factors that determine the brightness of a star?
distance from the sun and the age of the star
If a star has a large absolute brightness value but a low apparent brightness value is the star close or far away?
If a star IS very bright but LOOKS fairly dim, it must be far away.
The brightness of a star depends on how much the star puts out and how far away it is from?
The observer.
How do scientists determine the element present in a star?
By the star's spectrum.
What factors determine a stars brightness as seen from earth?
Distance from Earth, size of star, and temperature of star.
What factors determine a stars brightness seen from earth?
Distance from Earth, size of star, and temperature of star.
How do i put magnitade in a scentence that is in space?
Scientists use the term magnitude to describe a star's brightness.
