Earth's albedo is .39
-------------------------------------
The albedo is a measure of how much light the Earth reflects
The amount of light/energy falling on the Earth form the Sun is between 0.8 and 1.0 kW / m².

∙ 14y agoThat is called the apparent magnitude. Originally the brightest stars were called "magnitude 1", the weakest that could still be seen with the naked eye, "magnitude 6". The system has been formalized, now certain objects (several planets, the Moon, the Sun, some bright stars) actually have negative magnitudes; and of course, the range has been extended to weak objects that can only be seen with telescopes. In general, a larger magnitude numbers means an object is less bright.

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.
What compares the brightness of stars as if they were the same distance from earth?

Is it true that two stars that have the same brightness are the same distance from earth?
false
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.
How much light does Saturn radiate?
Because Saturn is 890.8 million miles from the sun, and its thick and turbulent atmosphere like Jupiter, it only gets about 1/83 the sunlight of Earth.
What is a the brightness of Mars as seen from earth?
it is doubble the brightness
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 a stars brightness as if it were a standard distance?
Theres `Absolute Magnitude` which is the brightness of a star at a set distance. Then there is `Apparent Magnitude` which is the apparent brightness from earth, regardless of distance.
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 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.

Is the brightness of the moon caused by the speed of it travelling around the earth?
No. The brightness of the moon is caused by the sun shining on it, just like the brightness of a beach, a snowdrift, a mountainside, or a lake, none of which travels around the earth.
Can the earth be affected if the brightness of the sun changed?
Absolutely, the result in the brightness of the sun would change the temperature, wind, light, and maybe even seasons on Earth
What is the name of the brightness of a star viewed from earth?
Apparent magnitude.
How does the earth benefit the sun?
the sun give us brightness
