Apparent magnitude.
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".
apparent magnitude (brightness of a star when viewed from Earth) depends on the size of the star, how hot it is, and its distance 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.
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).
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.
The brightness of a star is called visual magnitude. The lower the visual magnitude is the brighter the star is.
Apparent magnitude is a measure of how bright a star appears from Earth, taking into account its distance and how much light it emits. Absolute magnitude, on the other hand, is a measure of a star's intrinsic brightness if it were observed from a standard distance of 10 parsecs. It helps in comparing the true brightness of stars regardless of their distance from Earth.
A star's brightness as viewed by the unaided eye is measured using a scale called apparent magnitude. This scale quantifies how bright a star appears from Earth, with lower numbers indicating brighter stars. For example, a star with an apparent magnitude of 1 is brighter than one with a magnitude of 6, which is at the limit of what the average human eye can see under ideal conditions. Factors influencing a star's apparent brightness include its intrinsic luminosity, distance from Earth, and any interstellar material that may dim its light.
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
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.
1: The size of the planet.2: The planet's distance from the Sun.3: The "albedo" of the planet (the percentage of the Sun's light it reflects).If you mean how bright the planet appears to us on Earth, then the distance from Earth is obviously very important.
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.
