How Far Is The Moon From Mars?
The Moon is a highly recognizable astronomical object in the night sky. It’s also one of our solar system’s largest and most important objects.
The distance between the Moon and Earth constantly changes due to the tidal interaction between our planet and the Moon. As a result, the answer to how far the Moon is from mars will vary depending on the time of the year.
How Far Is The Moon From Mars?
Mars is one of our closest and most-familiar planets. We love to watch it shine brightly among the stars and always wonder how far it is from us!
The distance between Mars and Earth varies, but on average, it’s 140 million miles (225 million kilometers). In fact, at its closest point from the Sun – known as perihelion – it’s only about 128 million miles (206 million km) away.
When it’s at its farthest – called aphelion – Mars is about 154 million miles (249 million kilometers) away. The difference between these two distances isn’t very large, but it does mean it takes a little longer for a spacecraft to reach Mars than for an astronaut to get there.
Mars and Earth orbit the Sun at different speeds, constantly changing their distances. In addition, their orbits are not perfectly circular, meaning the two planets pass each other on average every 84 days.
But even if their distances remained the same, it still wouldn’t make much difference. The Moon is also close to the Sun, but it’s not the same. The Moon is closer to the Sun when it’s a new moon and farthest from the Sun when it’s a full moon.
So, if the Moon were only twice as far from Earth as it is, then the Sun would be on top of it, which could create some very bad tidal disasters! That’s why scientists always try to keep the distance between the two planets at an average of 142 million miles (228 million km).
You might think that it’s closer to Mars because the Moon is farther away from the Sun when it’s a new Moon. However, the Moon is closer to Mars when it’s at apogee than it is when it’s at perigee!
The Moon’s orbit around the Earth is elliptical, which means it goes far from the Earth at one point in its orbit, and then close to the Earth at another. This explains why the Moon looks a little larger when it’s at apogee and a little smaller when it’s at perigee!
How To Find The Moon’s Distance From Mars
When you see a photo of the Moon, it may look like it’s very close to Earth. Unfortunately, this isn’t entirely accurate – the Moon and Earth are an average distance of 384,400 kilometers (238,855 miles) from one another.
You’ll need a little math if you want to know how far the Moon is from mars. You’ll need to know how many astronomical units are between the Earth and the Moon and how close the Moon is to its apogee and perigee.
You’ll also need to know how long it takes for the Moon to go around the Sun. This is called a lunar day.
The Moon orbits the Earth in an elliptical path, meaning it’s closer at certain times and farther at others. At its apogee, the Moon is 252,088 miles (405,696 kilometers) from the Earth.
At its perigee, the Moon is 225,623 miles (363,104 kilometers) from the Earth.
These numbers can be confusing, so you’ll need to determine the astronomical units. Astronomers use these units of distance to measure the distance between the planets.
Now you’ll need to calculate how long it will take for the Moon to travel through the plane with you, your friend, and the center of the Earth. You can do this by using spherical trigonometry.
Once you know how long it will take for the Moon to pass through that plane, you’ll need to calculate its height. This can be done by calculating the angles of the spherical triangle and then subtracting those angles from 180 degrees.
Then you’ll need to add that height to the Earth’s radius, which is 8100 kilometers. Then you’ll need to subtract the planets’ radii from that and have the correct distance.
You can use a calculator or simply take a ruler and draw a line from the Earth to the Moon. Then you’ll need to measure the length of that line and write it down. You’ll then need to multiply that number by the average distance between the planets.
How To Find The Moon’s Apogee
The Moon is subject to several motions as it orbits the Earth, so its distance from us can vary. This is largely due to its orbital eccentricity, which is 5.49% (as major Solar System bodies go), and the effect of the Sun’s tidal force on its orbit.
As the Moon arcs away from us at perigee and returns to us at apogee, its distance varies by as much as 14% from our perspective. This is one reason it appears larger at perigee than at apogee, as shown in the photograph below.
It helps to consider how light behaves at different distances to make sense of the difference in angular size. Light intensity varies as the inverse square of the distance between the source and the observer, so the Moon shines brighter at apogee than at perigee by about 30%.
But few people ever notice this because they see the Moon in a sky that offers no absolute reference to judge its angular extent. The only way to observe the difference is to use a scale or to take photos of the Moon at perigee and apogee and compare them.
This experiment is simple:
- Find a night when you can see the Moon at perigee and apogee.
- Take pictures of it at both locations.
- Calculate the ratio of the sizes of the two images to get an idea of how large it is at each location.
For these calculations, we used a Web-browser-based Lunar Perigee and Apogee Calculator that prepares lists of close and farthest apogees for any given year and the interval separating each perigee or apogee from the nearest new or full Moon. The calculator also lets you select which of the two pictures you want to include in the calculation.
Using the ratio of image sizes from the calculator yields 405948 km for the apogee picture and 359861 km for the perigee picture, which closely matches the best estimates of angular size. However, the apogee to perigee ratio is a bit higher than the calculated value because of the tidal effects of the Sun’s gravitational field and the orbital eccentricity. This is why we recommend choosing the perigee or apogee moments as close as possible to the time of the full Moon (or near the same interval before and after), which will ensure that the differences in brightness are less likely to be masked by a change in phase.
How To Find The Moon’s Perigee
Every 29.5 days, the full Moon (or New Moon) coincides with the Moon’s closest approach to Earth — a phenomenon known as a supermoon. But not every full Moon is a supermoon because the Moon’s orbit changes during its 27-day cycle.
But a supermoon isn’t the only reason to pay attention to the Moon — the angular size of the Moon can vary dramatically depending on whether or not it is close to the Sun. When the Moon is closer to the Sun, it looks 10% larger and 30% brighter than when it is farther away.
This is due to the difference in angular size caused by the Moon’s orbital eccentricity. The eccentricity measures how far the Moon’s orbit varies from the elliptical shape of the Earth’s orbit.
Since the eccentricity varies from orbit to orbit, the distance the Moon is near the Earth varies from month to month. Typically, the Moon is nearest to Earth when it is at its perigee and farthest from the Earth at its apogee.
Because the angular size of the Moon varies so greatly from one phase to the next, it can be hard for someone to tell when they see a new moon or a full moon. However, you can easily tell by looking at a few pictures of the Moon.
If you have a clear sky and your camera is set to take pictures with no filters, you should see a small difference in the Moon’s angular size. But if you want to be sure, it is possible to make a scale that will allow you to compare images taken at apogee and perigee.
Then, you could flick a switch and compare the images. For example, it would be easy to see that the Moon is about 30% brighter at apogee than at perigee, even though it’s only about a day and a half closer to the Sun.
The difference between apogee and perigee is so large that the limb diameter of the Moon appears to be 1.1238 times its total distance from Earth! And, since a large part of the difference is the logarithmic response of the human eye, it’s not as noticeable as you might expect from this 30% difference in the intensity of the moonlight.

The distance between the Moon and Mars can vary greatly depending on their positions in their orbits around the Sun. However, on average, the Moon is approximately 238,855 miles (384,400 kilometers) away from Earth, while Mars is approximately 140 million miles (225 million kilometers) away from Earth. Therefore, the distance between the Moon and Mars can be calculated as the sum of their distances from Earth.
To understand the distance between the Moon and Mars, it is first necessary to understand their positions in the solar system. The Moon is Earth’s natural satellite and orbits around our planet at an average distance of 238,855 miles. On the other hand, Mars is the fourth planet from the Sun and has an average distance from the Sun of about 140 million miles. As a result, Mars is significantly farther away from the Earth than the Moon.
When Mars and the Moon are on opposite sides of the Sun, they are at their farthest distance from each other. The distance between the two can be as much as 250 million miles (400 million kilometers). However, when they are on the same side of the Sun, the distance between them can be as little as 34 million miles (55 million kilometers).
Regarding travel time, it would take astronauts about three days to travel from Earth to the Moon using the Apollo spacecraft, which had a maximum speed of around 24,790 miles per hour (39,900 kilometers per hour). However, traveling to Mars is a much more difficult and time-consuming task. The shortest possible travel time to Mars is around six months, and it would require a spacecraft traveling at a speed of around 34,175 miles per hour (55,000 kilometers per hour).
In summary, the distance between the Moon and Mars can vary greatly depending on their positions in their orbits around the Sun. On average, the Moon is approximately 238,855 miles away from Earth, while Mars is approximately 140 million miles away from Earth. Therefore, the distance between the Moon and Mars can be calculated as the sum of their distances from Earth. Traveling from Earth to the Moon takes about three days while traveling to Mars takes around six months.
