30+ Moon Facts: Exploring Our Closest Celestial Neighbor

The moon is the Earth’s natural satellite, which has fascinated humans for thousands of years. It is a subject of poetry, mythology, and scientific study.

The moon’s surface is full of craters, mountains, and valleys, and its phases have been used to track time for millennia. This article will explore some of the most interesting facts about the moon.

Facts About Moon:

The moon is not round:

Contrary to popular belief, the moon is not a perfect sphere. It is slightly flattened at the poles and bulges at the equator due to its rotation.

This shape is called an oblate spheroid. The difference in the moon’s diameter between its poles and its equator is about 6,800 kilometers.

The moon has no atmosphere:

The moon has no atmosphere, meaning no air or weather is on its surface. This also means that there is no protection from the sun’s radiation or meteor impacts.

The lack of an atmosphere also means that there is no sound on the moon, as sound waves require air to travel through.

The moon has gravity:

Despite its small size, the moon has enough gravity to affect the tides on Earth. The moon’s gravitational pull causes the oceans to bulge, creating high and low tides. The moon’s gravity also affects the Earth’s rotation, slowing it down slightly over time.

The moon is moving away from Earth:

The moon is moving away from Earth at a rate of about 3.8 centimeters per year. This is because the moon’s gravity is causing the Earth’s rotation to slow down, which in turn causes the moon to move away.

Scientists believe that in about 50 billion years, the moon will be far enough away from Earth that it will no longer have an effect on the tides.

The Moon Is Moving Away From Earth

The moon is covered in dust:

The moon’s surface is covered in a layer of dust called regolith. Meteor impacts and the constant bombardment of solar radiation create this dust.

The regolith is several meters deep in some areas, making the moon’s surface dusty and powdery.

The moon has a dark side:

The moon’s rotation is synchronous with its orbit around Earth, which means that the same side of the moon always faces Earth. This site is called the near side.

The other side of the moon, which is not visible from Earth, is called the far side or the dark side. The moon’s dark side was first photographed by a Soviet spacecraft in 1959.

The moon has moonquakes:

The moon experiences moonquakes, similar to earthquakes but caused by the Earth’s and the sun’s gravitational pull.

Moonquakes can also be caused by meteor impacts and the cooling and shrinking of the moon’s interior. Moonquakes can be quite strong, with some registering up to 5.5 on the Richter scale.

The moon is older than Earth:

The moon is about 4.5 billion years old, which is about the same age as the Earth. However, the moon formed about 30 million years before the Earth did.

Scientists believe the moon formed when a Mars-sized object collided with the early Earth, ejecting material that eventually formed the moon.

The moon has water:

Recent studies have shown that there is water on the moon, particularly near the poles. This water is not in liquid form but is instead frozen as ice.

The discovery of water on the moon has led to speculation that it could be used as a resource for future lunar exploration.

The moon has a magnetic field:

The moon has a weak magnetic field, much weaker than Earth’s. This field is believed to be caused by the moon’s iron-rich core.

The magnetic field also protects the moon’s surface from the sun’s solar wind, a stream of charged particles.

The moon has a strange smell:

Astronauts who have been to the moon have reported that the moon has a distinct odor. The smell has been described as similar to gunpowder or burnt charcoal.

The smell is believed to be caused by the combination of the moon’s dust and the exposure to the vacuum of space.

The moon has a lot of craters:

The moon’s surface is covered in craters caused by the impact of meteoroids and asteroids. There are thousands of craters on the moon, some of which are several kilometers wide.

The largest crater on the moon is the South Pole-Aitken Basin, which is over 2,500 kilometers wide.

The Moon Has A Lot Of Craters

The moon has a very low density:

The moon has a density of about 3.3 grams per cubic centimeter, much lower than Earth’s.

This is because the moon has less dense materials, such as rock and dust, than Earth’s heavier elements.

The moon has a significant effect on animals:

The moon’s gravitational pull affects not only the tides but also the behavior of animals. Many animals, such as sea turtles and birds, use the moon’s phases to navigate and time their breeding and migration patterns.

The moon is not the only moon in our solar system:

While the moon is Earth’s only natural satellite, other planets in our solar system also have moons.

Jupiter, for example, has 79 known moons, while Saturn has 82. Mercury, the smallest planet in our solar system, has no moons.

The moon is slowly rotating away from us:

The moon’s orbit gradually moves away from Earth at a rate of about 1.5 inches (3.78 cm) per year. This means that the moon will appear smaller in the sky in millions of years, and its effect on tides will be lessened.

The moon has “moon trees”:

During the Apollo 14 mission in 1971, astronaut Stuart Roosa brought along a canister containing hundreds of tree seeds.

These seeds were taken into space and orbited the moon before being returned to Earth. Many of the seeds were successfully germinated, and these trees are now known as “moon trees.”

The moon has an atmosphere (sort of):

While the moon is often described as having no atmosphere, it actually does have a very thin layer of gasses surrounding it.

This layer is called an exosphere and comprises helium, neon, and hydrogen. The exosphere is so thin that its particles rarely collide with each other.

The moon has lava tubes:

Beneath the moon’s surface, there are large tubes that were formed by volcanic activity. These tubes are known as lava tubes and can be up to 1,000 meters wide. Scientists believe these tubes could be used as a shelter for future lunar explorers.

The moon has a “mascon”:

A mascon, short for “mass concentration,” is a region on the moon’s surface with a higher-than-average density.

These regions were discovered in the 1960s by studying the moon’s gravitational field. The largest mascon on the moon is located in the center of the Imbrium Basin.

The moon has “moonquakes”:

Just like Earth, the moon experiences seismic activity. These moonquakes are caused by the gravitational pull of Earth, as well as the cooling and shrinking of the moon’s interior.

The moonquakes can range from minor tremors to more powerful quakes, with some registering up to 5 on the Richter scale.

The moon’s surface is covered in a layer of dust:

The moon’s surface is covered in a layer of fine dust, also known as regolith. The constant bombardment of meteoroids and asteroids creates this dust.

The regolith is several meters thick in some areas and can be dangerous to lunar explorers, as it can get into equipment and cause damage.

The moon is the only place in the solar system where humans have walked:

To date, the moon is the only celestial body other than Earth that humans have walked on. A total of 24 astronauts have traveled to the moon, 12 of them actually setting foot on its surface during the Apollo missions in the 1960s and 1970s.

The moon has a unique orbital pattern:

Unlike most of the other planets and moons in our solar system, the moon’s orbit is not perfectly circular.

Instead, it is slightly elliptical, meaning its distance from Earth varies throughout the month. This results in the moon appearing larger and brighter during a full moon when it is closest to Earth.

The moon is responsible for Earth’s axial tilt stability:

The moon plays a crucial role in stabilizing Earth’s axial tilt, which is the angle between the Earth’s equator and its orbit around the sun.

Without the moon’s gravitational influence, Earth’s axial tilt would vary wildly, leading to extreme climate changes and making life on Earth much more difficult.

The moon has “moonbows:

Just like rainbows, moonbows are a beautiful optical phenomenon caused by the reflection and refraction of light.

Moonbows occur when the moon’s light is refracted by water droplets in the air, creating a faint, colorful arc in the sky.

The moon’s surface is constantly changing:

While the moon may appear to be a static, unchanging object in the sky, its surface is constantly being reshaped by various processes.

These include impacts from meteoroids and asteroids, volcanic activity, and the effects of the moon’s atmosphere (such as it is).

The moon’s gravity affects the Earth’s weather:

The moon’s gravitational pull affects the tides and the Earth’s atmosphere. The moon’s gravity causes a slight bulge in the Earth’s atmosphere, which in turn affects the distribution of air pressure, leading to changes in the weather.
