An eclipse of the Sun can only occur at New Moon (see: Solar Eclipses for Beginners), while an eclipse of the Moon can only occur at Full Moon (see: Lunar Eclipses for Beginners). In any calendar year there are a minimum of two solar and two lunar eclipses.
If an eclipse of the Sun or Moon takes place on a given date, it is noted by a character next to the date in the table above. Solar eclipses are indicated as: T=Total, A=Annular, H=Hybrid and P=Partial. Lunar eclipses are indicated as: t=Total, p=Partial, and n=Penumbral.
Phases of the Moon Photo Gallery is an image collection showing the Moon's phases over a complete synodic month.

Astronomical Definitions
- Perihelion - the instant when a planet is closest to the Sun
- Aphelion - the instant when a planet is furthest from the Sun
- Perigee - the instant when the Moon is closest to Earth
- Apogee - the instant when the Moon is furthest from Earth
- Inferior Conjunction - the instant when a planet passes between Earth and the Sun (Mercury or Venus)
- Superior Conjunction - the instant when a planet passes on the opposite side of the Sun from Earth (Mercury or Venus)
- Greatest Elongation - elongation is the apparent angle between a planet and the Sun as seen from Earth; during eastern elongation (E), the planet appears as an evening star; during western elongation (W), the planet appears as a morning star
- Opposition - the instant when a planet appears opposite the Sun as seen from Earth
- Conjunction - the instant when a planet appears closest the Sun as seen from Earth
- Occultation - the Moon occults or eclipses a star or planet
- Ascending Node - the point where a planet crosses from the southern to northern portion of its orbit
- Descending Node - the point where a planet crosses from the northern to the southern portion of its orbit
