Phases of The Moon

Viewing the Moon!!!

First and Third Quarter Differences

The first quarter always happens in the evening sky, while the last quarter takes place in the morning sky. At first quarter, the moon in its month-long orbit has just passed the sun and coming out into the evening sky. Lots of people see it. Since the last quarter rises around midnight, many fewer see it, because it comes up only after people have gone to bed. At first quarter, the illuminated area of the moon is growing or "waxing." Each night it gets larger, until a week later the moon is full. At last quarter it is getting smaller night by night, or "waning," until at new moon it has shrunk to nothing.

First and Third Quarter Similarities

The first quarter and third quarter moons (both often called a "half moon"), happen when the moon is at a 90 degree angle with respect to the earth and sun. So we are seeing exactly half of the moon illuminated and half in shadow.

Different Sites

Astronauts and people on Earth view the Moon differently because we are both looking at it from different angles.

Waxing and Waning

One of the most important important differences between the 1st and 3rd quarter is that the 1st quarter is waxing and the 3rd moon is waning.Waxing are the moons going counterclockwise from the New Moon.Waning moons are the moons that come after the full moon.
