How far away is the Moon? [1]
What is the distance between the Earth and the Moon? The answer is not as simple as you think…. The Moon is the most recognisable object in the night sky, and has an enormous impact on life here on Earth
The average distance between the Earth and the Moon is 384 400 km (238 855 miles).. Light travels at 300,000 kilometres per second, so it takes about 1.3 seconds for light to travel from the Moon back to the Earth
Some are very close, but they are all at least slightly elliptical in shape. Astronomers can measure how near to a perfect circle an orbit is by calculating its ‘eccentricity’.
How Far Away Is the Moon? [2]
Often when we see drawings of the Earth and the Moon, they look really close together.. The Moon is an average of 238,855 miles (384,400 km) away
When the Moon is the farthest away, it’s 252,088 miles away. The Moon definitely seems close because we can see it so well without a telescope,
The moon will fall to earth in 100 years, how fast is the asteroid that knocked it down? [3]
Your mechanIsm for making the Moon collide with Earth in 100 years would not work.. LONG ANSWER PART ONE: ANOTHER SOLAR SYSTEM OBJECT COLLIDES WITH EARTH
But it is perfectly possible for astronomers in the present time or some future time to discover that an astronomical body is going to impact the Earth at some specified time in their future.. Some present day astronomers are working on projects to discover and catalog as many asteroids and comets with Earth crossing orbits as possible
The hope is that if some asteroid or comet is calculated to be on a course that will eventually impact on Earth with devastating results, the calculated impact date will be far enough in the future for the asteroid or comet to be diverted in time.. For example, Biela’s Comet had an orbit that crossed the orbit of Earth:

How far is the moon from Earth? [6]
It’s the brightest object in our night sky, but how far is the moon from Earth?. The moon’s distance from Earth affects the strength of ocean tides and the appearance of solar eclipses in our skies.
The moon does not orbit Earth in a perfect circle, so there are places along its trip when it is either closer or farther away from our planet than this average distance.. Shortest distance between the moon and Earth: Perigee
If perigee coincides with a full moon phase, this is generally called a supermoon. The term is not a scientific one, but it is used by the skywatching community when the full moon appears within 90% of perigee.
How Far is the Moon From Earth? [7]
Countries and businesses around the world are eyeing it with economic hopes and dreams. But what is it, anyway, how far is the moon from Earth, and is there really water up there?
The moon is Earth’s only natural satellite, though we’ve recently picked up an unnatural satellite, as well. Scientists think the unnatural satellite, made by humans, is the remains of a rocket from a failed mission to the moon in 1966.
However, there have long been questions about this theory, like what happened to Theia afterward? Is the moon composed of a mixture of materials from Earth and Theia? A NASA study from 2019 cast doubt on the Giant Impact Theory. Specifically, scientists couldn’t find enough of a large group of Earth elements in the moon, even though the moon should contain them, per the Giant Impact Theory.
How Far Is the Moon? [8]
If only there was a ruler long enough to reach the moon. How far away is the moon? It’s not as easy to answer as you think because the moon has an elliptical orbit.
So, it varies between 225,622 miles and 252,088 miles due to its elliptical orbit. This distance is equivalent to the “lunar distance” measurement.
Using these reflectors, we can determine with extreme precision how far away the moon is.. In fact, we know the moon is ever so slightly moving away from the Earth by about an inch and a half per year.
Lunar distance (astronomy) [9]
The instantaneous Earth–Moon distance, or distance to the Moon, is the distance from the center of Earth to the center of the Moon. Lunar distance (LD or ), or Earth–Moon characteristic distance, is a unit of measure in astronomy
The lunar distance is on average approximately 385,000 km (239,000 mi), or 1.28 light-seconds; this is roughly 30 times Earth’s diameter or 9.5 times Earth’s circumference. A little less than 400 lunar distances make up an astronomical unit.
The actual distance varies over the course of the orbit of the Moon, from 356,500 km (221,500 mi) at the perigee to 406,700 km (252,700 mi) at apogee, resulting in a differential range of 50,200 km (31,200 mi).[3]. Lunar distance is commonly used to express the distance to near-Earth object encounters.[4] Lunar semi-major axis is an important astronomical datum; the few millimeter precision of the range measurements determines semi-major axis to a few decimeters; it has implications for testing gravitational theories such as general relativity,[5] and for refining other astronomical values, such as the mass,[6] radius,[7] and rotation of Earth.[8] The measurement is also useful in characterizing the lunar radius, as well as the mass of and distance to the Sun.
How Far Is the Moon? [10]
It might not be the largest natural satellite in the Solar System, but size doesn’t matter when it comes to the Moon.. The Moon is the fifth largest satellite in the Solar System and the second-densest satellite after Io, one of Jupiter’s moons
So how far is the Moon? Like all celestial bodies, the Moon is in constant motion, and its always someplace else. On average, however, the Moon is located at around 384,400 kilometers / 238,855 miles away from Earth, or 1.29 light-seconds.
The Moon can get as far as 406,700 km / 252,711 mi away from Earth – apogee – and as close as 356,400 km / 221,456 mi away – perigee – however, consider this. The Moon, due to gravitational interactions with our Earth, is drifting away from us at around 4 cm / 1.5 inches every year
How Far Is The Moon From Earth? [11]
Besides the Sun, the moon is perhaps the most recognizable object in the Earth’s skies. To our eyes, it appears to be the same size as the Sun, and even during a solar eclipse, the moon fits rather perfectly within the Sun’s frame
The moon only appears as large as it does due to the fact that it is located fairly close to the Earth. In fact, the moon is so close to us that it is the only celestial object whose surface features are visible with the naked eye
It may not seem like it, but the distance between the Earth and the moon changes over the course of the moon’s orbit. That’s because the moon doesn’t orbit the Earth in a perfect circle but rather in an elliptical manner (think of it as slightly egg shaped).
What is the distance between the Earth and the Moon and what would fit between the Earth and the Moon [12]
What is the distance between the Earth and the Moon?. How many lands fit between Earth and Moon? What matters is the number of Earths in a row that fit between the centers of the Earth and the Moon, so we only need the distance between these centers and the diameter of the Earth
How big is the Moon relative to the Earth and how far is the Earth from the Moon?. The moon’s size is about 3.500 kilometers wide, equivalent to more than 1/4 the size of Earth (about 12.600 kilometers wide)
The Moon travels around Earth in an oval orbit at 36.800 kilometers per hour. The Moon has no atmosphere, so temperatures range from -184 degrees Celsius at night to 214 degrees Celsius during the day, with the exception of the poles where the temperature is constantly -96 degrees Celsius.
How far is The Moon from Earth? Accurate distance data. [13]
The distance of The Moon from Earth is currently 377,073 kilometers, equivalent to 0.002521 Astronomical Units. Light takes 1.2578 seconds to travel from The Moon and arrive to us.
In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.. The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth.
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
How far away is the moon from the earth and how long would it take to get there? [14]
It’s the 50th anniversary of the date that man first set foot on the moon, as Neil Armstrong took that giant leap for mankind as the first man to tread the lunar surface.. And there have been a fair few missions to the moon since then, with 12 astronauts in total having walked on its surface.
So just how far is the moon from the earth – and would it still take so long to reach it now?. The distance between the moon and the earth varies as its orbit around the earth is elliptical – meaning the distance changes over time.
On average though, the moon is around 384,400km away from earth – putting a distance of around 30 earths between the two planets.. It really depends on how you’re travelling and what is travelling to the moon – as human missions usually take longer than passenger-free vehicles – and it also depends whether or not you’re planning to stop at the moon or just passing it.
Moon – Places in the News [15]
The moon is Earth’s only natural satellite and the only astronomical body other than Earth ever visited by human beings. The moon is the brightest object in the night sky but gives off no light of its own
The moon’s average radius (distance from its center to its surface) is 1,079.6 miles (1,737.4 kilometers), about 27 percent of the radius of Earth.. Because the moon has less mass than Earth, the force due to gravity at the lunar surface is only about 1/6 of that on Earth
And if that person dropped a rock, the rock would fall to the surface much more slowly than the same rock would fall to Earth.. Despite the moon’s relatively weak gravitational force, the moon is close enough to Earth to produce tides in Earth’s waters
What is the Distance to the Moon? [16]
The short answer is, the average distance to the Moon is 384,403 km (238,857 miles). But before you go thinking that this is the final answer, you need to consider a few things
Hence, the number 384,403 km, is an average distance that astronomers call the semi-major axis. At its closest point (known as perigee) the Moon is only 363,104 km (225,622 miles) away
This means that distance from the Earth to the Moon can vary by 43,592 km. That’s a pretty big difference, and it can make the Moon appear dramatically different in size depending on where it is in its orbit

How far is the Moon in light years from Earth? [18]
Distances in space, no pun intended, are truly astronomical in size. Within the Earth’s solar system we often use Astronomical Units as a measure of distance, with the Earth being 1 AU from the Sun
This means that on a scale if the Earth was an inch from the Sun, a single light-year would be a point about 1 mile away.. Become a Study.com member to unlock this answer! Create your accountView this answer

How Far Away Is the Moon, and How Long Is Its Day? [20]
Earth’s only natural satellite, the Moon, orbits Earth at an average distance of 1.28 light-seconds.. It also shows only one side to Earth at all times, a trait called tidal locking
How does a day look like on the tidally locked Moon? How far or near does it get to Earth, and what happens then?. How Many Times Does the Moon Orbit Earth in a Year?
The word month is derived from the time the Moon takes to complete one set of its phases from new moon, to full, and back to new again.. This time also reflects the Moon’s complete orbit around Earth, which is exactly 27 days 7 hours, and 43 minutes
A mind-boggling photo from NASA’s Lucy probe shows how far the moon is from Earth. Can you spot it? [21]
– A new photo from NASA’s Lucy spacecraft captures Earth and the moon together — a rare sight.. – The image reveals the vast space between us and the moon
Our planet is obvious, on the far right side of the image, but the moon is a little harder to spot. NASA’s Lucy probe, a mission to a group of asteroids near Jupiter, snapped this photo as it zoomed past Earth on October 13
It varies, but on average the moon is 238,855 miles from Earth. On a cosmic scale, that’s not very far, but you could fit 30 Earths into that space
Moon [22]
THE MOON IS SMALLER ACROSS (IN DIAMETER) THAN THE UNITED STATES IS WIDE.. If the Earth were hollow, about 50 moons would fit inside.

Earth to Moon Distance (in km, miles, AU, and light-years) [23]
And the average distance from the Earth to Moon is around 384400 kilometers. But the orbital path of the moon around the earth is not a perfect circle, though it varies
In actuality, the distance between the moon and earth always changes. Because our moon does not orbit Earth in a perfect circle but the path is a little elliptical
So, there is always variation between the earth and moon’s actual distance. At some point, the moon is closest to earth and at some point in the orbital path, the moon would be the farthest from the earth
Does your car’s odometer have enough miles to drive to the moon? [24]
(WKBN) – Cars can add up the miles over a number of years, especially older ones. Some cars and trucks may even provide an outstanding amount of miles before it is time to retire the vehicle.
Let’s take a look at how far your car could have traveled and how long it would have taken to get there if you did not stop at all.. The moon is about 238,855 miles away from the earth
We know that is not possible, but if your car has 238,855 miles on it, you can say it has enough miles to drive to moon.. Below is a list of locations and how many miles away they are traveling at 65mph non-stop:
Scale of space: Can you fit all the planets between the Earth and Moon? [25]
I’ve been getting some emails and tweets asking me if a viral video called “209 Seconds That Will Make You Question Your Entire Existence,” about astronomical scale, is correct or not. Before we get into it, the answer is, “Yes, pretty much.” I have some nitpicks, but first take a look:
The big question most people have asked is about the part that starts at 00:20, where it shows the Earth and the Moon, and says all the planets in the solar system can fit in between.. They can, but it depends on how you measure things.*
If you do that, the planets (note: the video didn’t include Pluto, so I won’t either) combine to 380,016 kilometers (you can find these numbers in lots of places on the Web and do the math yourself to check mine). There’s a bit of uncertainty in some of the planets’ sizes, so call it +/- 100 km
