  • Our topic for today is Phases of Moon.

  • The moon revolves around the earth in a fixed orbit.

  • The moon does not have its own light.

  • Sun gives light to the moon.

  • When the moon is between the earth and the sun, we cannot see the moon at all.

  • This is because the side of the moon facing the earth does not get sunlight.

  • This is called the new moon.

  • After 2 to 3 days, we can see some part of the moon.

  • This phase is called the waxing crescent.

  • As the moon is gaining light, that is, expanding in illumination, we use the term waxing.

  • About a week after the new moon, we can see half of the moon.

  • This phase is called first quarter.

  • Two or three days after the first quarter, more than half of the moon is visible.

  • This phase is called the waxing gibbous.

  • About two weeks after the new moon, we can see the full moon.

  • This is because the full side of the moon facing the earth gets sunlight.

  • Now, the moon begins its return journey from the full moon to the new moon.

  • The next phase is called the waning gibbous.

  • As the moon is now losing light, that is, decreasing in illumination, we use the term waning.

  • The next phase is the last quarter followed by the waning crescent.

  • When the moon comes back between the earth and the sun, it enters the New moon phase again.

  • Number of days between 2 new moons is 29 as the moon takes approximately 29 days to revolve once around the earth.

  • These changing shapes of the moon are called phases of the moon.
