SOUTH MISSISSIPPI (WLOX) - A full moon rises in Saturday night’s sky. May’s full moon is known as the Flower Moon as this is the time of year when abundant flowers appear.

Why is this month’s full moon called a blue moon?

There are two types of blue moons:

  • Type One: Usually, there is only one full moon per month. Rarely, a second full moon occurs in one month and it is called a blue moon.
  • Type Two: Usually, there are only three full moons per season. Rarely, four full moons occur in one season. The third of those four full moons is called a blue moon.

For this month’s full moon, the blue moon is a “type two,” as it is the third full moon in a season with four full moons.

A blue moon doesn’t actually look blue. They look just like every other moon.

Instead, these moons are called blue to signify their rarity-- on average, they occur about every two-and-a-half years, according to NASA.
