Group B Phases Of The Moon

0moon_phases_diagram.jpg

The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. From Earth we see the Moon grow from a thin crescent to a full disk (or full moon) and then shrink back to a thin crescent again before vanishing for a few days

The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles. These are called "phases" of the Moon

A full moon appears as an entire circle in the sky. The full moon is given different names, depending on when it appears. For example, the "Harvest moon" is the full moon that appears nearest to the Autumnal Equinox, occurring in late September or early October. Some other full moon names (by month) include:
.January Moon After Yule, Wolf Moon, or Old Moon
.February Snow Moon or Hunger Moon
.March Sap Moon, Crow Moon, or Lenten Moon
.April Grass Moon or Egg Moon
.May Milk Moon or Planting Moon
.June Rose Moon, Flower Moon, or Strawberry Moon
.July Thunder Moon or Hay Moon
.August Grain Moon or Green Corn Moon
.September Fruit Moon or Harvest Moon
.October Harvest Moon or Hunter's Moon
.November Hunter's Moon, Frosty Moon, or Beaver Moon
.December Moon Before Yule or Long Night Moon.

As the moon circles the Earth, the shape of the moon appears to change; this is because different amounts of the illuminated part of the moon are facing us. The shape varies from a full moon (when the Earth is between the sun and the moon) to a new moon (when the moon is between the sun and the Earth).

BLUE MOON
When two full moons occur in a single month, the second full moon is called a "Blue Moon." Another definition of the blue moon is the third full moon that occurs in a season of the year which has four full moons (usually each season has only three full moons.)

GIBBOUS MOON
A gibbous moon is between a full moon and a half moon, or between a half moon and a full moon.

HALF MOON
A half moon looks like half a circle. It is sometimes called a quarter moon (this Moon has completed one quarter of an orbit around the Earth from either the full or new position and one quarter of the moon's surface is visible from Earth).

CRESCENT MOON
A crescent moon is part way between a half moon and a new moon, or between a new moon and a half moon
