May’s blue moon will illuminate the night sky this weekend, but don’t expect the moon to actually look blue.<\/p>\n

On Sunday, May 31, a blue moon<\/a> will occur, which means there will be two full moons during the month of May. May’s Flower Moon already occurred on the first day of the month, and the blue moon will occur on the last day of the month.<\/p>\n

The phenomenon is rare and only happens once every two to three years, according to\u00a0NASA<\/a>. This rarity is where the moon gets its name \u2013 not because of its color.<\/p>\n

What makes this moon even more unique is that it will be a micromoon. The phenomenon occurs when the moon is at its farthest point from Earth during that month, according to NASA. The moon could be around\u00a0251,000 miles away from our planet.<\/p>\n

Because of the distance, the moon might appear smaller than usual.<\/p>\n

Here’s what to know about the rare blue moon.<\/p>\n

(Jonathan Ernst\/Reuters)When is the blue moon?<\/p>\n

The moon is set to peak on Sunday, May 31, at 4:45 a.m. ET, according to the\u00a0Farmer’s Almanac<\/a>.<\/p>\n

While the moon will peak early Sunday morning, it will still look full a few days before and after it peaks.<\/p>\n

What causes a blue moon?<\/p>\n

The phenomenon happens because, unlike a calendar month, which is around 30 to 31 days, except for February, the moon’s lunar cycle is around 29.5 days, according to\u00a0NASA<\/a>.<\/p>\n

So, once every two to three years, a full lunar cycle will occur within a month, giving us a full moon at the beginning of the month and another at the end of the month, which is what we know as the blue moon.<\/p>\n

How often do blue moons occur?<\/p>\n

Blue moons occur every two to three years.<\/p>\n

Is the blue moon actually blue?<\/p>\n

The blue moon won’t actually look blue.<\/p>\n

The term “blue moon” originated in the 16th century, when people said “the moon is blue” to mean something that seemed impossible, according to\u00a0Encyclopedia Britannica<\/a>.<\/p>\n

How rare is a blue moon?<\/p>\n

It isn’t a common occurrence, hence the expression “once in a blue moon,” and only occurs every 2.5 years, according to\u00a0NASA<\/a>.<\/p>\n

The last blue moon occurred on Aug. 19, 2024, when the moon was a\u00a0super blue moon<\/a>, meaning, unlike the micromoon, it was closest it had been to Earth that month and appeared brighter and larger.<\/p>\n

When is the next blue moon?<\/p>\n

The next time two full moons will take place in the same month will be in December 2028, according to\u00a0Time and Date<\/a>. A seasonal blue moon, which is the third full moon that will occur in a season, will occur on May 20, 2027.<\/p>\n
