Harvest Moon


We've learned about all of the phases of the moon, and the blue moon.

Another special type of moon is called the Harvest Moon or Hunter's Moon.
The harvest moon is special because it looks red!

Remember a long time ago we learned about the different colors of light, ROY G BIV?

When the moon doesn't look high up in the sky, but instead low down towards the ground, we call that on the horizon. And when you're not looking up in the sky but out on the horizon, you're looking through the sky (the atmosphere) into space at a different direction, and the color Red (from ROY G BIV) stands out more, which makes the moon look red!

It's called a harvest moon because it shows up in the fall when farmers are harvesting their crops.

Waning Crescent


We've learned now about the moon's lunar phases: new moon, waxing crescent, first quarter, waxing gibbous, full, waning gibbous and last quarter.

After last quarter, the moon continues to get darker on the right side.
Once it is almost totally dark and there is only a crescent of light on the left side, that is called waning crescent.

Remember that when the light crescent is on the right side, that is waxing crescent.

Last quarter moon


We've learned now about the moon's lunar phases: new moon, waxing crescent moon, first quarter moon, waxing gibbous, full moon and waning gibbous.

After waning gibbous, the moon continues to get darker on the right side.
Once it is about half dark, that is called the last quarter moon.

Remember that when the left side is dark, that is the first quarter moon.

Waning Gibbous


We've learned now about the moon's lunar phases: new moon, waxing crescent moon, first quarter moon, waxing gibbous and full moon.

After the moon is full and bright, it starts to get dark again.
The next phase after full moon is called waning gibbous.

Waning sort of means going away, so the moon is almost full and getting less full every day.
The waxing gibbous moon was a little dark on the left side.
The waning gibbous moon is a little dark on the right side.

Waxing Gibbous Moon


We've learned now about the moon's lunar phases: full moon, new moon, waxing crescent moon and first quarter moon.

The next phase after first quarter is called waxing gibbous.

When the moon is almost full, but only a small crescent on the left side is dark, that is called waxing gibbous.

First Quarter Moon


We've learned now about the moon's lunar phases: full moon, new moon and waxing crescent moon.

The next phase after waxing crescent is called first quarter.
When you look up in the night sky and you see the right half of it, that is a first quarter moon.

A quarter is when you divide something up into four equal parts, a quarter is one of those parts.
So if you divide the moon into four parts: 1 back left (dark), 2 back right (dark), 3 front left (dark), 4 front right (light)
You can see that only one of the four parts of the moon has sun light on it.

Waxing Crescent


We know that a full moon is when the sun is on the other side of us, shining right on the moon, and a new moon is when the moon is totally dark because it is in between the earth and the sun.


Right after a new moon, the moon will start to get some sunlight on it's right side. This makes a crescent shape, so we call it a crescent moon. Since the moon is going to get more full as the days go on, we use the word waxing to say that it is going to get fuller. So we can say the moon is waxing crescent.

New Moon


We know that a full moon is when the sun is on the other side of us, shining right on the moon.

A new moon is the opposite of a full moon. It is when the moon is in between the earth and the sun. When it is there, we can't see the moon in the night sky.

Full Moon


A full moon happens about once every 29 days.
Since there are 28, 30 or 31 days in each month we usually see a full moon once every month.

The full moon happens because the sun is shining right on the part of the moon that we can see.
Sometimes the sun is shining on a different side of the moon that is not facing us, and we would not see the full moon.

Lunar eclipse


We know that a solar eclipse is when the moon gets between the earth and the sun.

A lunar eclipse is when the earth gets between the moon and the sun. Since the earth is blocking the sunlight shining on the moon, the moon will go dark in the sky and you won't be able to see it.

Blue moon


When people talk about a blue moon they don't mean that the moon actually turns blue!
A full moon comes around every 29 days, so there is usually only one full moon per month.

If there are two full moons in the same month, the second one is called a blue moon.
This doesn't happen very much, so there is a saying "once in a blue moon" that means not very often.

Lunar Phase


A full moon is when you can see the whole moon bright in the night sky.

What about when the moon isn't full and only part of it is showing?
Or when you can't see the moon at all in the sky?

The changing of the moon in the sky is called the lunar phase.
The light on the moon changes because it orbits the earth, and when the part we can see does not have sunlight shining on it, it is dark.
When the sunlight is shining on it all the way, it's bright.

Solar eclipse


Remember orbit means that one thing spins around the outside of another thing.

We know the moon orbits around the earth, and is kind of close to the earth.
We also know the earth orbits around the sun.

What happens when the moon spins around the earth, and is right between the earth and the sun?
That's called a solar eclipse.

The moon gets right between the earth and the sun, and blocks out the sun!

When the moon is in just the right position, it blocks out pretty much the whole sun, and the earth gets dark light night time, even though it's day time!

Moon Tides


The moon orbits the earth about every 27 days, and the earth spins around once every day.

Because the moon is so big, as it is spinning around the earth it affects the oceans and lakes.
This is called tide.

When a part of the ocean is facing where the moon is, the water rises up.
Then when the earth spins and the moon orbits, the water goes down.
When the ocean is facing totally opposite of where the moon is, the water rises up again.
And when the earth spins again the water goes down.

If you live on an ocean or lake, you can see the water rise up to the beach for a few hours, then go back out for a few hours.

Gravity on the Moon


When the astronauts walked on the moon, it wasn't the same as walking here on earth.

The gravity on the moon is a lot less than earth.
That means if you dropped a ball to the ground, it would fall slowly like a balloon!

If you are on the moon and you jump up in the air, you won't come down fast like normal,
you'll float down slowly like a balloon too.

If you weigh 50 pounds on Earth, you would only weigh about 8 pounds on the moon.

Lunar rocks


When the Apollo missions visited the moon, they brought back over 800 pounds of rock!

Those lunar rocks (or moon rocks) have helped us to study what the moon is made of.

Lunar Lava Tube


We just learned how lava tubes on earth are tunnels underground formed by lava channels.

There are also lava tubes on the moon!

Scientists think they could make great places for astronauts to live if we ever have people stay on the moon.

Lunar Soil


The dust, dirt and broken rocks on the moon are called lunar soil, or regolith.

When the Apollo 11 crew landed on the moon, their boots left footprints in the soil.

Lunar impact craters


Lunar impact craters are large circle shaped things on the moon that almost look like big empty swimming pools.

They were created by smaller asteroids that crashed into the moon and left marks there.

Lunar Grabens


Let's keep learning about the moon!

Another thing you can see on the moon looks like a big long ditch.

This is called a graben.

One of the grabens on the moon is called Rima Ariadaeus:
