Zeta Eridani (Zibal) is a white to white blue star in the constellation Eridanus.
It has an apparent brightness of +4.80 and an absolute brightness of +1.97.
Zibal (Zeta Eridani) has a spectral class of A5 which means it is a white to white-blue star on the main sequence.
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
It is indicative of their relative brightness, measured in candelas (units of brightness, also called candle power).
A lux meter is a device that measures surface brightness.
A pencil has nothing to do with the brightness of a light bulb.
Zeta Eridani (Zibal) is about 120 light years from us.

An apparent brightness is the brightness of a star as measured by an observer.
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
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".
The brightness levels on a DSiXL can be changed to be from a brightness of 1(lowest) to a brightness of 5(highest). The screens can be dark depending on where you are.
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.
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.
