For more information on how the Moon appears in Earth's sky, see lunar phase.

The center one represents the axis of the world and the 108 smaller ones represent the four lunar phases, each with 27 days.

Over 28 days, the moon goes through a full cycle of lunar phases.

Unlike "heroes", the lunar phase plays a part in their union conditions.

Each month has no connection with the lunar phases.

A lunar phase is a "transformation" that the moon goes through.

Each lunar phase can be identified by the appearance of the moon and the time of the month.

The Moon had complete mapping coverage during the two month lunar phase of the mission.

The art on the CD is of the lunar phase.

At the end of every 19 years, the lunar phases repeat themselves.
