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.
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.
The apparent brightness of the sun would decrease because the intensity of sunlight weakens with distance. By moving the Earth from 1 AU to 2 AU, the distance between the Earth and the Sun doubles, resulting in a decrease in the amount of sunlight reaching Earth and causing a decrease in apparent brightness.
The apparent magnitude of a star is a measure of its brightness as seen from Earth, the lower the number, the brighter a star is. Ex. a star that has an apparent magnitude of -20 is WAY brighter from Earth than a star with a apparent magnitude of 20.
Two factors that affect a star's apparent brightness are: 1.) The distance between the Earth and the star 2.) The absolute magnitude (the actual brightness) of the star Hope that helps :P

Apparent Brightness = luminosity/4(pi)x(distance)^2
How dense it is, and how far away it is.
If the brightness is 'B' right now, when the object is at a distance 'D' from your eye, then-- If the object moves closer, to only [ 1/2 D ] from you, the brightness increases to [ 4 B ].-- If the object moves farther away, to [ 2 D ] from you, the brightnesses decreases to [ 1/4 B ].
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).
There are at least 2 main factors that may affect osmosis. These 2 factors are amount of water and membrane permeability.
