O Avatar: The Game incluiu detalhes significativos sobre Pandora e o sistema Alpha Centauri que não foi incluído no filme, notavelmente que o "ciclo dia-noite" é altamente variável e que a noite em Pandora pode ser quase (10%) tão brilhante quanto o dia, dependendo de sua posição orbital.
A ausência da discussão do dia / noite real de Pandora tende a sugerir que é aproximadamente o mesmo que a Terra (ie aproximadamente 12 horas do dia e 12 horas da noite, dependendo da estação).
Pandora receives significant light from Alpha Centauri B (ACB). Because of this, for half the Polyphemian year its nights are never dark, but instead are more like Earthly dusk. At the closest point in its orbit, ACB is about 2,300 times as bright as Earth's full moon; at its farthest, it is still one hundred and seventy times as bright. During the other half of the year, when ACB is in the daytime sky, many Pandoran nights are illuminated both by Polyphemus's huge disk and reflected light from other nearby moons. Truly dark nights are uncommon. Polyphemus occasionally eclipses ACB at night for about one hundred minutes, but the light reflected by the planet still keeps the night from being dark. When ACB shares the daytime sky with ACA, at its closest it adds about half a percent to the total illumination. When the 2 stars are close together in the sky, the effect of ACB's more orange light is unnoticeable, but as they separate over the years, an orange tint may be seen in areas shadowed from ACA's direct illumination. At its most distant, ACB is about 2,700 times dimmer than ACA and does not produce noticeable lighting effects. However, it still appears as a blindingly-bright tiny orange disk in the sky.
Because of its high axial tilt (29 degrees), Pandora exhibits considerable annual variation in the day-to-night ratio. In addition, its elliptical orbit produces seasonal temperature variations and a range in daytime illumination of about ten percent.
