The Moon is a fascinating place! It’s the only spot in the universe, besides Earth, where humans have set foot. The Moon is called a natural satellite because it travels around Earth, just like Earth travels around the Sun. Its path isn’t a perfect circle, so sometimes it’s closer to us, and sometimes it’s farther away.
The Moon is made of metal and rock, much like Earth and other planets such as Mercury, Venus, and Mars. Its outer layer, called the crust, is covered with lunar soil. This soil is made of tiny rock pieces, similar to sand or clay. Gravity, the force that pulls things together, keeps us on Earth from floating away. Because Earth’s gravity is stronger than the Moon’s, you would weigh less on the Moon. For example, if you weigh 66 pounds on Earth, you’d weigh only 11 pounds on the Moon!
Earth is much larger than the Moon. Earth is about 8,000 miles wide, while the Moon is about 2,000 miles wide, which is one-fourth the size of Earth. The distance from Earth to the Moon is about 239,000 miles, and it takes astronauts about three days to travel there. In comparison, the Sun is about 93 million miles away from Earth!
Astronauts have visited the Moon several times. Neil Armstrong was the first person to walk on the Moon on July 20, 1969, followed by Buzz Aldrin. Before them, spacecraft had only orbited the Moon and Earth. NASA, the United States space program, organized five more Moon landings after Armstrong’s mission, with the last one in 1972.
The Moon’s surface is mostly rock and dust, with some mountains. Meteorites have created craters on the Moon, but there is no rain, snow, or wind to change its surface like on Earth. Earth has an atmosphere made of gases, including oxygen, which helps protect life and regulate temperatures. The Moon has no atmosphere, so its temperatures can be extreme, and there’s no air or water for humans to survive.
It takes Earth about 365 days to orbit the Sun, while the Moon takes about one month to orbit Earth. The Moon also spins on its axis, an imaginary line from the North Pole to the South Pole. Earth spins once every 24 hours, but the Moon spins much slower, taking about 27 days for one complete rotation.
The Moon causes tides in our oceans. Tides are when ocean water rises and falls, creating deep and shallow areas near the shore. The Moon’s gravity pulls on the ocean, causing these tides. Depending on where you are and the positions of the Earth and Moon, the Moon might look bigger or smaller. Sometimes you see just a sliver, and other times you see a full Moon, but the Moon is always round.
When you look at the Moon, you’re seeing sunlight reflecting off its surface. The part of the Moon that is lit up is the part facing the Sun. Without the Sun, we wouldn’t see the Moon at all. The different shapes of the Moon we see are called phases.
The new moon happens when the Moon is between the Sun and Earth, and the side facing us is dark.
Next is the waxing crescent, where a small part of the Moon starts to show, like a banana shape.
Then comes the first quarter, or half moon, where we see half of the Moon lit up.
The waxing gibbous phase is when more than half of the Moon is visible, but it’s not yet full.
The full moon is when the Earth, Moon, and Sun are aligned, and the Moon is fully lit.
After the full moon, the waning gibbous phase begins, where the Moon starts to look smaller.
The third quarter is similar to the first quarter, but it’s the last third of the Moon’s orbit.
Finally, the waning crescent leads back to the new moon, and the cycle starts again.
In ancient times, people used the Moon’s phases to navigate and keep track of time. Next time you look at the night sky, notice how the Moon lights it up, especially during a full moon. You might even see the Moon during the day! Maybe one day, you’ll be the next person to walk on the Moon.
Moon Phase Diary: Over the next month, keep a Moon Phase Diary. Each night, look at the Moon and draw what you see. Try to identify which phase the Moon is in, using the descriptions from the article. At the end of the month, compare your drawings to see how the Moon changed over time. Discuss with your family or friends why these changes happen and what phase comes next.
Create a Moon Model: Use a flashlight, a small ball (like a ping pong ball), and a larger ball (like a basketball) to create a model of the Earth, Moon, and Sun. The flashlight represents the Sun, the basketball is Earth, and the ping pong ball is the Moon. In a dark room, shine the flashlight on the ping pong ball while moving it around the basketball. Observe how the light creates different phases on the ping pong ball, just like the Moon’s phases. Try to identify each phase as you move the Moon around Earth.
Gravity Experiment: Explore the concept of gravity by comparing how different objects fall. Gather a few small items like a feather, a coin, and a piece of paper. Drop them from the same height and observe how they fall. Discuss why some objects fall faster than others and relate this to how gravity on the Moon is different from Earth. Imagine how it would feel to jump on the Moon and how high you could go!

The Moon and its phases are fascinating topics. Besides Earth, the only other place in the universe that people have visited is the Moon. The Moon is classified as a natural satellite because it orbits the Earth, just like the Earth orbits the Sun. Sometimes the Moon is farther away from the Earth than at other times because its orbit is not a perfect circle.
The Moon is made up of metal and rock, similar to Earth, Mercury, Venus, and Mars. Its outer shell, or crust, is covered by lunar soil, which consists of fine rock particles, akin to sand or clay. Gravity is the force that pulls objects together, keeping you and everything else on Earth from floating away. You weigh more on Earth than you would on the Moon due to the stronger pull of gravity here. For example, if you weigh 66 pounds on Earth, you would only weigh 11 pounds on the Moon.
Earth is larger than the Moon, measuring about 8,000 miles across, while the Moon is only about 2,000 miles across, or one-fourth that size. This distance is roughly equivalent to traveling from Utah to New York. The distance from Earth to the Sun is about 93 million miles. Although the Sun may seem close because we can feel its warmth, it is actually very far away. If it were possible to travel to the Sun by plane, it would take about 19 years to reach it. In contrast, the distance from Earth to the Moon is approximately 239,000 miles, and it takes astronauts about three days to get there.
Astronauts have landed on the Moon several times, with Neil Armstrong being the first person to walk on its surface on July 20, 1969. Buzz Aldrin followed him about 20 minutes later. Before these two astronauts, spacecraft had orbited both the Moon and Earth, but none had landed. NASA, the United States space program, organized five more Moon landings after Armstrong’s mission, with the last one occurring on December 11, 1972.
While there are some mountains on the Moon, its surface is primarily composed of rock and dust. Meteorites have caused craters on the Moon, but the surface does not change due to the absence of rain, snow, or wind, unlike Earth, which has various landforms such as mountains, deserts, ice, and forests. The atmosphere surrounding Earth is made up of different gases, including oxygen, and it protects life by trapping heat from the Sun and absorbing harmful rays, regulating temperatures to prevent extremes.
Earth can support living organisms like plants and animals due to its atmosphere and the presence of water. In contrast, the Moon has no atmosphere, and its temperature can vary drastically, making it impossible for humans to live there. There is also no water or air on the Moon.
It takes about 365 days, or one year, for Earth to orbit the Sun, while the Moon takes about one month to orbit Earth. The Moon also spins on its axis as it orbits Earth. An axis is an imaginary line from the North Pole to the South Pole. Earth takes about 24 hours to complete one spin, but the Moon spins very slowly, taking about 27 days for one complete rotation.
Did you know that the Moon causes the tides in our oceans? Tides are when the water in the ocean rises and falls, creating deep and shallow areas near the shore. During low tides, you may see small creatures, shells, and other habitats. The ocean tides rise due to the gravitational pull of the Moon. Depending on the positions of the Earth, Moon, and your location, the Moon may appear larger or smaller. Sometimes you can see only a small sliver, while at other times, you can see a full Moon. However, the shape of the Moon remains consistently round.
What you see when you look up at the night sky is the Sun’s light reflecting off the Moon’s surface. The illuminated part of the Moon is the section that the Sun is shining on. Without the Sun, the Moon would be invisible. Most nights, you can only see part of the Moon, which is referred to as a moon phase.
The first phase is called a new moon, occurring when the Moon is between the Sun and Earth. The far side of the Moon is in full sunlight, while the side facing you is dark. The next phase is the waxing crescent moon, where a thin sliver of the Moon becomes visible, resembling a banana. A crescent moon rises during the day and sets before midnight.
Next is the first quarter moon, often called a half moon, where we can see half of the Moon while the other half is dark. This is followed by the waxing gibbous phase, which is less than a full moon but more than half. The full moon occurs when the Earth, Moon, and Sun are aligned, making the Moon more illuminated than in any other phase.
After the full moon comes the waning gibbous phase, where the Moon appears to be getting smaller. The third quarter moon is similar to the first quarter moon, as it represents the last third of the Moon’s orbit around Earth. The waning crescent moon follows, leading back to another new moon, and the cycle begins again.
In ancient times, people used the Moon and its phases to navigate at night and keep track of time. The next time you look up at the night sky, notice how it lights up during a full moon. Look for the Moon during the daytime as well, and see if there are times it disappears completely. Perhaps one day, you’ll be the next person fortunate enough to walk or bounce on the Moon.
