This Month’s Full Moon Is Going To Look Smaller Than Usual — Here’s Why

When we think about the full moon, we think about a big, even glowing hunk of rock in the sky, but July’s full moon is going to look a little different on account of it being a micro full moon. OK, you’re probably wondering what a micro full moon is, because the July 2018 Buck Moon will be one, and the term "micro full moon" is not exactly a commonly used one.

Many of us know about "super moons" — aka, a phenomenon that makes the moon appear to us Earthlings as much larger than normal. A super moon occurs when the moon is at the point in its orbit where it is closest to Earth, or "the perigee." But "micro moons"? That makes the moon look tiny, and it’s due to "the apogee," aka the point when the center of moon is at a place in its orbit where it is farthest from the Earth. So, not only does the micro moon appear almost 15 percent smaller than a super moon, but it also appears duller — by about 30 percent, to be exact. If you observe the moon regularly, you’ll notice a pretty significant difference between the sizes of the micro full moon, the standard full moon, and the super full moon.

If you needed any encouragement to step outside and make a point of observing the sky, after Jul. 27, we won’t be treated with a micro full moon again until Sep. 14, 2019. Though we’ve seen micro full moons before, they’re quite rare.

Because this year’s micro full moon falls in July, it’s considered a Buck Moon. The nickname was given to the moon by the Algonquin tribes as a reminder about what to expect from their deer population. Each year, the male deer, aka Bucks, shed their antlers. Come July, the antlers start to grow back. It will take the remainder of the summer for their antlers to grow back, but deers are more aggressive with antlers, so it was good for the people to be aware of when this process begins. July’s full moon is also known as the Thunder Moon, because it typically falls during the stormiest time of the summer season. So don’t forget to find the time to head outside and observe this rare and very symbolic event.
