The full moon also known as Poornima or Full moon night.
- The moon is a natural satellite of the Earth that we see nearly every night. This ensures that the moon follows a predictable course around the earth.
- Even as the moon orbits around the planet, the gravitational pull between the earth and the natural satellite keeps it in its orbit.
- When the moon body is behind the earth and sun, we can see the entire illuminated portion, this is a full-moon or Paurnami.
- When it is between the sun and earth we can only see the dark portion and a new moon or Amavasya occurs. Between these two extremes, we see intermediate phases such as a half-moon and crescent.
