Zodiacal light is sunlight scattered from dust in the solar system. Comets in the inner solar system eject lots of dust along with gas as they heat up.

A faint band of light concentrated along the ecliptic and therefore running through the zodiac. It is solar light scattered back towards the Earth by small dust particles lying in the plane of the planetary system.

The combination of this fine asteroid dust, as well as ejected cometary material, produces the zodiacal light. This faint auroral glow can be viewed at night extending from the direction of the Sun along the plane of the ecliptic.

The amount of airglow and zodiacal light is quite variable but given the most optimal condititions the darkest possible sky has a brightness of about 22 magnitude/square arcsecond.

It also was very faint, only about half as bright as the notoriously difficult Gegenschein (counterglow - a bright patch in the zodiacal light, directly opposite to the Sun).

The red data points are my modified and new DIRBE results which use a different zodiacal light model than the one used by Hauser et al. (1998, ApJ, 508, 25).

Then, at 9:10pm I have revisited Pleiades (M45) noticed earlier with the unaided eye at the apex of Zodiacal Light. As usual that open cluster was delightful in binoculars however 6 inch scope revealed also the faint fan of Merope Nebula.

Other factors that will affect the sky, and are not typically considered, are the presence of natural forms of light pollution, such as the Gegenschein, the zodiacal light, and aurora.

This glow is called the zodiacal light and is caused by sunlight being scattered off of the various dust particles which travel around the Sun.

This dust reflects sunlight and sometimes can be seen as a wedge-shaped sky glow called the zodiacal light before sunrise or after sunset. Dusty discs around other stars that arise through the same processes are called 'exozodiacal' clouds.

Small quantities of dust are also present in the interplanetary medium and are responsible for the phenomenon of zodiacal light. Some of the dust is likely interstellar dust from outside the solar system.

Of the white-light corona (the corona seen by the eye at a total solar eclipse), that portion which is caused by sunlight scattered or reflected by solid particles (dust) in interplanetary space. The same phenomenon produces zodiacal light.

The F corona extends from the solar corona from about two or three solar radii far beyond the Earth into space, so that it can actually be seen at night as a faint glow along the ecliptic, the glow is known as zodiacal light.
