What else can I help you with?
Is a star's absolute magnitude dependent on its distance from the observer?
No, a star's absolute magnitude is a measure of its intrinsic brightness regardless of its distance from the observer. It is a standardized measure that allows for comparison of the brightness of stars at a set distance.
Is a small star brighter than a large star?
It all depends on the luminousity of the star and the relative distance of the observer.
What word means how bright a star appears?
The word you are looking for is "apparent magnitude," which is a measure of how bright a star appears to an observer on Earth. It is based on the star's intrinsic brightness and its distance from Earth.
What 3 factors affect how bright a star appears from earth?
The 3 factors that affect a star's brightness as viewed from earth, are: The star's age, distance from earth, and actual magnitude (scale a star's brightness is measured in).
Apparent movement of a star used to measure its distance from earth?
Parallax is the apparent movement of a star when viewed from different positions in Earth's orbit around the Sun. By measuring this shift in position, astronomers can calculate the distance to the star using trigonometry. The closer a star is to Earth, the greater its parallax angle and the more accurately its distance can be determined.
A star's brightness is determined by the amount of light it gives off and its distance from?
The observer.
Is a star's absolute magnitude dependent on its distance from the observer?
No, a star's absolute magnitude is a measure of its intrinsic brightness regardless of its distance from the observer. It is a standardized measure that allows for comparison of the brightness of stars at a set distance.
What characteristic of star?
By their size, distance, and temperature
How the latitude of an observer may be determined by observation of the pole star?
The angle between the Pole Star and the horizon is equal to your latitude.
How bright does a star appear from earth?
It depends on its intrinsic brilliance and its distance from the observer
Which characteristic determines the color of a star?
The colour of the star is determined by its age , mass , and composition.
When was Sydney Star Observer created?
Sydney Star Observer was created in 1979.
How is the distance to a star determined using the measure of parallax?
The distance to a star can be determined using the measure of parallax by observing the star from two different points in Earth's orbit around the Sun. By measuring the apparent shift in the star's position against more distant background stars, astronomers can calculate the star's distance based on the angle of the parallax.
Is a small star brighter than a large star?
It all depends on the luminousity of the star and the relative distance of the observer.
If the distance between us and a star is doubled the apparent brightness is decreased by a factor of four true or false?
True. The apparent brightness of a star is inversely proportional to the square of the distance between the star and the observer. So if the distance is doubled, the apparent brightness will decrease by a factor of four.
What word means how bright a star appears?
The word you are looking for is "apparent magnitude," which is a measure of how bright a star appears to an observer on Earth. It is based on the star's intrinsic brightness and its distance from Earth.
What three factors determine the magnitude of star?
The apparent magnitude of a star is dependent on the star's size, temperature and distance from where it is observed. An absolute magnitude is determined by the same three factors, but the distance is fixed at 10 parsecs.
