How Far Are The Moon And Back?
The moon is the most prominent object in our skies, hugely impacting Earth. It is also the largest moon in our solar system and has an enormous role as a natural satellite for the Earth.
When the moon is at its perigee or apogee, it moves farther away and closer to Earth, which causes it to appear larger and smaller in our skies. It’s also possible for a lunar eclipse to coincide with either perigee or apogee, which produces a supermoon.
1. The Distance Between The Earth And The Moon
The distance between the Earth and the Moon varies over time. At its closest point, it’s 363,104km away from the planet – while at its farthest, it’s around 405,696km away.
This is because the Moon orbits the Earth elliptically, meaning it doesn’t orbit us in a circle like our planet.
Currently, the distance between the two planets is 238,897 miles (or 384,467 km) and that’s still changing slowly — it moves at a rate of 1 1/2 inches per year.
The Moon is about 60 times the size of Earth, so it’s quite a distance for such a tiny thing. It’s also the closest planet to our Sun so it can influence our atmosphere and the tides of our oceans.
2. The Distance Between The Moon And The Sun
The Sun and Moon form part of our solar system. The Sun is a star that gives out heat and light, while the Moon is a natural satellite that orbits Earth.
Both the sun and moon are round objects that appear bright in the sky when seen from the Earth. However, they are very different from each other in size and shape.
The sun is about 400 times larger than the moon and much farther away from the Earth. This fun coincidence allows the two to appear nearly equal in size to Earth.
3. The Distance Between The Moon And Mars
If you ever can look out into space, you might notice a familiar red planet. Mars is the fourth planet from the Sun and is a relatively close cousin of Earth.
We have already sent probes and rovers to visit this world.
You might even think of it as the Red Planet, thanks to its iron-rich soil and rusty appearance.
However, while you might think that these two objects are quite similar, the distance between them is pretty vast!
For example, when the Moon is closest to the Earth (perihelion), it’s 363 104 km (225 623 miles) away. But at its farthest point from the Earth (aphelion), it’s 154 million miles (249 million kilometers) away!
4. The Distance Between The Moon And Venus
Venus is one of the most visible planets in our sky, next to the Sun and the Moon. It can be seen easily with the naked eye or binoculars, but a telescope is required for more detailed views.
It’s a hot gas giant with a surface temperature of around 900 degrees Fahrenheit (475 Celsius). Even if humans could survive the conditions, traveling to Venus would be a challenging endeavor.
Like all the planets in our solar system, Venus orbits the Sun in an elliptical orbit. As a result, its closest and furthest points change over time.
5. The Distance Between The Moon And Mercury
Mercury is one of the most mysterious planets in the solar system. Its orbit is elongated, taking it as close to 29 million miles (47 million kilometers) and as far as 43 million miles (70 million kilometers) from the Sun.
Because of its distance from the Sun, it has exceptionally high temperatures on its surface. During the day, its surface can reach 800 degrees Fahrenheit (430 degrees Celsius), but it drops to minus 290 degrees Fahrenheit (minus 180 degrees Celsius) at night.
Its axial tilt is just 2 degrees concerning its plane of orbit around the Sun, so it does not experience seasons like other planets. However, because its temperature varies dramatically between day and night, it dwarfs any seasonal changes we might observe on Earth.
6. The Distance Between The Moon And Saturn
The Moon and Saturn will appear next to each other in the night sky from about 6:45 pm local time through 1:30 a.m. EST on January 23, 2018.
Saturn is a yellow-ringed gas giant that orbits the Sun with 82 natural satellites. It is the second largest planet in our solar system.
Unlike other planets, it has no landmass but a thick layer of liquid metal and a vast atmosphere.
In addition to its main body, Saturn has seven rings surrounding it.
The planet also has several moons, including the icy giant Titan and a large planet Mercury. Some moons travel within gaps in Saturn’s rings, while others go further out from Saturn.
7. The Distance Between The Moon And Uranus
Uranus, the seventh planet in our solar system, is 1.7 billion miles (2.5 billion km) from Earth at its closest point and 1.89 billion miles (3 billion km) away at its farthest. The distance between these two points changes depending on the planet’s elliptical orbit around the Sun.
During its orbit, Uranus’s closest approach to Earth occurs once per year. This moment is called Uranus’s opposition.
During this time, you can see the planet as it would look from our Earth. The planet shines at magnitude 5.7, which is brighter than the stars.
8. The Distance Between The Moon And Neptune
Neptune is the fourth largest planet in our solar system, but it’s the smallest and farthest from the sun. As a result, its surface temperature is colder than the other outer planets, and its thick atmosphere makes it hard or impossible for life to form.
It has 14 moons, named after various lesser sea gods and nymphs in Greek mythology. Four of them are regular satellites: Naiad, Thalassa, Despina, and Galatea, and one is a discovery called Hippocamp, designated initially S/2004 N 1.
The other 12 are irregular, some with counter-orbital orbits that pull them closer to Neptune than the planet’s rotation causes. The largest is Triton, which follows a retrograde orbit that’s tilted -23 degrees. It’s believed that this will eventually break it apart, forming a ring around Neptune visible from Earth.
9. The Distance Between The Moon And Pluto
Pluto is a dwarf planet and a member of the Kuiper Belt, a disc-like zone of tiny icy worlds that orbit beyond Neptune. These dwarf planets have rocky cores and mantles of water ice.
A new moon was recently discovered orbiting Pluto by the Hubble Space Telescope. This moon, P5, is six to 16 miles across and circles Pluto in a 30,000-mile-radius orbit.
The Moon is a small, rocky planet with an elliptical orbit around Earth that has some wobble because of the gravitational effect of other planets in our solar system. Its closest approach to the Earth (called perigee) is less than 357,000 km from the planet’s center, while its farthest distance away (called apogee) is about 348,000 km.
10. The Distance Between The Moon And Mars
There are plenty of questions people have about how far the Moon is from Earth and what it means for us. But figuring out the distance between the two isn’t as straightforward as it might sound.
It’s not even a straight-line distance!
That’s because Mars is orbiting around the Sun at a dizzying speed. It takes about half a Martian year to circle the Sun (known as perihelion) and a full Martian year to go from perihelion to aphelion, its furthest point from the Sun.
This makes it a challenging place to visit, especially if you want to stay long enough for an extended visit. That’s why many people have envisioned using one of Mars’ moons as a base from which astronauts could observe and explore the Red Planet.
How Far Are The Moon And Back? Better Guide
The distance to the moon and back depends on several factors, including the position of the moon in its orbit and the spacecraft’s trajectory.
The average distance from the Earth to the moon is approximately 238,855 miles (384,400 kilometers). This distance can vary depending on the position of the moon in its orbit, which changes over time. At its closest point (perigee), the moon is approximately 225,623 miles (363,104 kilometers) from Earth, while at its farthest point (apogee), it is approximately 251,000 miles (405,500 kilometers) away.
To calculate the distance of a round trip to the moon and back, we need to double the distance between Earth and the moon, which gives us:
Distance to the moon and back = 2 × 238,855 miles = 477,710 miles
This means a round trip to the moon and back is approximately 477,710 miles (769,071 kilometers) long.
Humans have traveled to the moon and back on several occasions, starting with the Apollo 8 mission in 1968, which orbited the moon without landing. The Apollo 11 mission in 1969 was the first to successfully land humans on the moon and return them safely to Earth. Other missions followed, with the final Apollo mission taking place in 1972.
During the Apollo missions, spacecraft traveled to the moon using a free-return trajectory, which allowed them to return to Earth without needing to perform a rocket burn. The spacecraft would fly around the moon’s far side and use its gravity to slingshot back toward Earth. The total distance traveled by the Apollo missions varied depending on the mission’s trajectory and the exact distance to the moon at the time of the mission.
For example, during the Apollo 11 mission, the spacecraft traveled 953,054 miles (1,536,835 kilometers) to reach the moon, land on its surface, and return to Earth. The spacecraft traveled to the moon at approximately 25,000 miles per hour (40,000 kilometers per hour) and returned to Earth at approximately 36,000 miles per hour (58,000 kilometers per hour).
In addition to the Apollo missions, other spacecraft have traveled to the moon and back on uncrewed missions. These include the Soviet Union’s Luna program, which launched several robotic missions to the moon in the 1960s and 1970s, and more recent missions by China’s Chang’e program and NASA’s Lunar Reconnaissance Orbiter.
Overall, a round trip to the moon and back is approximately 477,710 miles (769,071 kilometers) long and can vary depending on the position of the moon in its orbit and the spacecraft’s trajectory. Humans have traveled to the moon and back on several occasions, with the Apollo missions being the most well-known.
