Astronomy:Zodi
From HandWiki
Short description: Unit of measurement in astronomy
The zodi is a unit of zodiacal dust.[1] One zodi is the amount of zodiacal dust in the inner Solar System.[2] This dust absorbs light from the Sun and re-radiates it as thermal radiation. The luminosity of the zodiacal dust in the Solar System is about [math]\displaystyle{ 10^{-7} }[/math] relative to the luminosity of the Sun,[3] and in practice, this is the observable characteristic defining one zodi.
