Earth’s closest cosmic neighbor, the Moon has been fascinating humankind for centuries. Be it the spellbinding light it casts across the face of the Earth during night hours, or the more obvious role it plays in the tides that shape it, the Moon has occupied important places within our lives.
Well, what is the distance between the Moon and Earth? It is a very simple question and the answer not so simple indeed! Because the distance does change according to its elliptical orbit. And in this article, we will discuss the distance in miles, feet, and yards, and give you a cool look at its orbit.
The Average Distance from the Moon to Earth
The distance between the Moon and Earth is not fixed.
It orbits Earth in an elliptical path, meaning that the distance from Earth changes over time. However, on average, the distance is approximately 238,855 miles (384,400 kilometers). To break this down:
- Miles: 238,855 miles
- Feet: 1,261,280,000 feet
- Yards: 420,426,666 yards
Why This Distance Varies
The Moon does not travel in a perfect circle; instead, its orbit is elliptical, meaning that the distance varies depending on the location in its orbit.
- Perigee: The point where the Moon is closest to Earth, about 226,000 miles away.
- Apogee: The point where the Moon is farthest from Earth, about 253,000 miles away.
This variation is known as the Perigee syzygy moon, or supermoon, which occurs
When its orbit brings it closest to Earth while simultaneously aligning with the Sun. During a supermoon, it appears about 14% larger and 30% brighter than when at its apogee.
Perigee is the point in the Moon’s elliptical orbit when it is closest to Earth.
Syzygy is the alignment of three celestial bodies, Earth, the Moon, and the Sun during events like full moons or new moons.
How Big Is the Moon Compared to Earth?
| Attribute | Moon | Earth |
|---|---|---|
| Size Comparison | A little more than one quarter the size of Earth | Larger than the Moon |
| Mean Radius | 1,079.6 miles (1,737.5 km) | 3,958.8 miles (6,371 km) |
| Mean Diameter | 2,159.2 miles (3,475 km) | 7,917.6 miles (12,742 km) |
| Surface Area | 14.6 million square miles (38 million km²) | 196.9 million square miles (510.1 million km²) |
| Proximity to Earth | Average distance: 238,855 miles (384,400 km) | N/A |
Despite its size, it appears larger due to its closeness to Earth. It is the fifth largest satellite in the solar system.

Comparing the Distance to Familiar Landmarks
To help visualize just how far the Moon is, here are some comparisons:
- The distance from New York to Los Angeles is approximately 2,450 miles. You could travel back and forth from New York to LA about 97 times before reaching the Moon.
- The distance from Earth to the Moon is more than 30 times the circumference of Earth, which is about 24,901 miles.
This gives you an idea of the immense scale of the distance from Earth. While traveling there might sound like something out of science fiction, it’s something humans have actually done.
Lunar exploration has been ongoing for decades, with the Apollo missions successfully landing astronauts on the Moon in the 1960s and 70s.
Moon Mass, Density, and Gravity Explained
- Mass: 7.35 x 10^22 kg (about 1.2% of Earth’s mass)
- Density: 3.34 g/cm³ (second densest moon in the solar system, after Jupiter’s Io)
- Gravity: 16.6% of Earth’s gravity (objects weigh six times less on the Moon)
- Example: A person weighing 100 lbs on Earth would weigh only 16.6 lbs on the Moon
- Impact of Lower Gravity: Allows extraordinary feats like long jumps of up to 60 feet
Converting Moon’s Distance into Feet
While miles give us a general sense of the Moon’s distance, converting that measurement into feet makes it even easier to understand the sheer scale. One mile equals 5,280 feet.
So, when you convert the Moon’s distance to feet:
1 mile = 5,280 feetTo convert the Moon’s distance:
- 238,855 miles × 5,280 feet = 1,261,280,000 feet
The Moon is approximately 1.26 billion feet away from Earth on average.

Visualizing 1.26 Billion Feet
To put this into perspective, let’s look at a few structures:
The Burj Khalifa:
The world’s tallest building, stands at 2,717 feet tall. You could stack the Burj Khalifa 465,000 times and still not reach the Moon.
Comparison with the United States Distance:
The distance across the United States (from coast to coast) is about 2,500 miles. If you drove from the East Coast to the West Coast, you’d still be about 100 miles short of the Moon.
The Moon’s Distance in Yards
Now that we’ve explored the distance in miles and feet, let’s convert the Moon’s distance into yards. Since 1 yard = 3 feet, we can calculate the Moon’s distance in yards:
1 yard = 3 feet
1,261,280,000 feet ÷ 3 = 420,426,666 yards
So, on average, the Moon is approximately 420 million yards away from Earth.
Comparing This to Everyday Objects
Football fields:
A standard football field is 100 yards long, including the end zones. If you laid out football fields end to end, you could stretch 4.2 million football fields from Earth to the Moon!
Skyscrapers:
The Empire State Building in New York is 1,454 feet tall (including its antenna). It would take about 870,000 Empire State Buildings stacked on top of each other to reach the Moon.

How Does Earth’s Moon Compared to Other Moons?
The Moon’s Unique Proportions
Earth’s Moon is unique in many ways when compared to the other moons in our solar system. While it isn’t the largest moon—Jupiter’s Ganymede holds that title—it is the fifth largest. What makes Earth’s Moon particularly notable is its relative size compared to its host planet.
The Moon is about 1/4 the diameter of Earth, making it proportionally the largest moon relative to its planet in the solar system. This unique size to planet ratio contributes significantly to Earth’s stability, including its axial tilt, which impacts climate and seasons.
Comparisons to Other Moons
In contrast, other moons orbiting the giant planets like Jupiter and Saturn are much smaller in comparison to their respective planets. For example:
- Ganymede: Larger than Mercury, but its host planet Jupiter is 317 times the mass of Earth.
- Titan: Saturn’s largest moon, with a thick atmosphere, is also much smaller in proportion to Saturn.
Why Does the Moon’s Distance Vary?
As mentioned, the Moon’s orbit is elliptical, and this variation in distance leads to differences in its apparent size and brightness. Two main events contribute to this:
Perigee and Apogee
- Perigee: When the Moon is closest to Earth (about 226,000 miles). During a supermoon, it looks significantly larger in the sky.
- Apogee: When the Moon is farthest from Earth (about 253,000 miles). It appears much smaller than during a supermoon.
These variations are not only fascinating but also essential for lunar gravitational force, which influences Earth’s tides. The Moon’s gravitational force creates tidal bulges in the Earth’s oceans, affecting everything from weather patterns to coastal ecosystems.
How Far Is That in Light Seconds?
In astronomy, light seconds are useful for measuring very large distances: a light second is defined as the distance light travels in one second a distance well over seventeen thousand miles, or about 186,282 miles (299,792 kilometers).
The Moon exists at a distance of about 238,855 miles from the Earth, which means that it is approximately equal to 1.28 light seconds. So this gives us a sense for how highly close the Moon is, in terms of travel by light. Yet, even if the Moon seems far, light takes little more than about a second to travel between Earth and the Moon.
How Far is the Moon from the Sun?
The Moon orbits Earth, and since Earth is about 93 million miles (150 million kilometers) from the Sun, the Moon’s distance from the Sun is essentially the same. This distance can fluctuate slightly depending on the Moon’s position in its orbit around Earth.
However, the average distance remains around 93 million miles, or 150 million kilometers, making it nearly identical to the distance Earth is from the Sun.

How Long Does it Take to Get to the Moon from the Earth?
Traveling to the Moon from Earth is a remarkable journey, but the trip is relatively short in terms of time. The time it takes depends on the spacecraft’s speed and trajectory, but typically, it takes around 3 to 4 days to travel from Earth to the Moon.
This time frame was followed by the Apollo missions, which used a trajectory called the Trans Lunar Injection (TLI), designed to take the spacecraft from Earth to the Moon efficiently.
How Long is a Day on the Moon?
A day on the Moon, or the time it takes to complete one full rotation on its axis, is quite different from a day on Earth. A lunar day lasts about 27.3 Earth days. This period is equal to the time the Moon takes to orbit Earth once.
Interestingly, because its rotation period is the same as its orbit around Earth, one side constantly faces our planet. This phenomenon is known as synchronous rotation or tidal locking, which means that we only ever see one hemisphere of the Moon from Earth.
Is the Moon Moving Away from the Earth?
Yes, the Moon is slowly moving away from Earth. It is not a dramatic change, but over time, the distance between the two has been gradually increasing. The Moon is receding at an average rate of about 1.5 inches (3.8 cm) per year. This phenomenon occurs due to the tidal interactions between Earth and its satellite.
As the Earth’s tides, caused by the Moon’s gravitational pull, create friction, this friction slows Earth’s rotation, transferring momentum, causing it to slowly drift away. Over millions of years, this gradual movement has accumulated, but for now, it remains a tiny, almost imperceptible shift.
Historical and Scientific Significance of the Moon’s Distance
Understanding the distance between the Moon and Earth is vital for space exploration, and it has played a significant role in human history.
Lunar Exploration
The Apollo missions were a pivotal part of the space race and human achievement. The first successful landing in 1969 by the Apollo 11 mission allowed astronauts to study the surface, collect samples, and place instruments that still help us study it today.
The GRAIL mission (Gravity Recovery and Interior Laboratory) was another important milestone, helping to map the Moon’s gravity with high precision.
Spacecraft Navigation
The distance between the Earth and the Moon is essential for planning spacecraft trajectories. When NASA or other space agencies send probes to Earth’s natural satellite, they calculate the exact distance at the time of launch to ensure the spacecraft arrives at the correct location.
Tidal Effects
The Moon’s proximity to Earth is directly tied to the Earth’s tidal patterns. The lunar gravitational force is responsible for high tides and low tides. The Moon’s influence on tides is a critical factor for coastal communities and marine ecosystems.
Comparison of the Moon’s Distance to Other Planets
