how long moon from earth?

Answer 1

200 light years .What is a light year ? It is if a body travels at the speed of light which is 300,000 miles /second for 1 year that speed is called light year. Imagine how distant the moon will if it is 200 light years.

Answer 2

About 238,000 miles or one and a quarter light seconds. On average. This is what is called the semi-major axis of the orbit (which is an ellipse).

In any one orbit there is a near point to the earth (perigee) and a far point away from the earth (apogee) and thus 13 of these in a calendar year,

Here are the next few coming up

Apogee: Mar 19 18:40 357815 km
Perigee: Apr 3 8:39 406326 km

Apogee: Apr 17 5:56 357137 km
Perigee: Apr 30 10:58 406208 km

Apogee: May 15 15:11 359392 km
Perigee: May 27 22:02 405456 km

Apogee: Jun 12 17:08 363777 km
Perigee: Jun 24 14:26 404538 km

Apogee: Jul 9 21:39 368533 km
Perigee: Jul 22 8:44 404150 km

The apogees are not all the same distance as one another, nor are the perigees.

The moon is slowy moving away from the earth at a rate of about 2 inches a year. Calculate that backgwards and you can see were once much closer to one another in our 4.5 billion-year history than we are now.

As regards how long it takes to get there, the Apollo astronauts needed 3 days, But the current New Horizons spacecraft winging its way to Pluto passed through the moon's orbit in under 12 hours in January 2006.

Answer 3

The average distance between Earth and Moon is approximately 30 times Earth's diameter.

If you could fly to the Moon at a constant speed of 1000 kilometers per hour, which is the speed of a fast passenger jet, it would take sixteen days to get there. Apollo astronauts reached the Moon in less than four days even though they coasted "uphill" almost the entire distance. They got a fast start.

The Sun happens to be 400 times the Moon's diameter, and 400 times as far away. That coincidence means the Sun and Moon appear to be the same size when viewed from Earth. A total solar eclipse, in which the Moon is between the Earth and Sun, blocks the bright light from the Sun's photosphere, allowing us to see the faint glow from the corona, the Sun's outer atmosphere.

When the Moon is at apogee, it is 11% farther from Earth than it is at perigee. This is far enough that it cannot entirely block the bright light, so eclipses which occur near apogee are not total.


Perigee 363,300 km
Mean 384,400 km
Apogee 405,500 km


Gravitational interaction (tides on the Earth caused by the Moon) transfers kinetic energy from Earth to the Moon, slowing Earth's rotation and raising the Moon's orbit, currently at a rate of 3.8 centimeters per year.

Earth and Moon Compared

The Moon has approximately 1/4 Earth's diameter, 1/50 Earth's volume, and 1/80 Earth's mass. Earth is very dense overall (it is the densest planet in the Solar System), but the Moon is light for its size. The difference is partly because Earth has a large core of iron and other heavy metallic elements, while the Moon has only a small core, if it has a core at all. The Moon's surface gravity is 1/6 of Earth's, and escape velocity from the surface is about 1/5 of Earth's.

The Moon's surface is covered with rock and grit that are mostly dark-gray minerals, so it reflects light poorly compared to Earth, which always has highly-reflective clouds. The Moon reflects visible light about 1/3 as well as Earth, and because of its much smaller size, has a visual brightness less than 1/40 that of Earth, when both are fully illuminated and seen from the same distance -- a difference of four stellar magnitudes.

Answer 4

dude.....this guy who said 200 light yr...does he knw wat a light yr is..???????? it is if sm body travels at the speed of light which is 300000 miles /second for 1 full year that speed is called light year........it is used to calculate distance not time....seems like dis guy needed 2 points...n the correct answer to ur question is...down here....

The average distance from the Earth to the Moon is 384,403 kilometres (238,857 miles), which is about 30 times the diameter of the Earth. The Moon has a diameter of 3,474 kilometres (2,159 miles) – about one-third that of the Earth. It is the fifth largest moon in the Solar System behind Ganymede, Titan, Callisto, and Io. The Moon makes one complete orbit about the Earth every 27.3 days, and the periodic variations in the geometry of the Earth-Moon-Sun system are responsible for the lunar phases that repeat every 29.5 days. The gravitational attraction of the Moon is largely responsible for the tides on Earth (with a secondary contribution from the Sun).

Answer 5

The average distance from the Earth to the Moon is 384,403 kilometres

Answer 6

The distance varies, since the moon's orbit is an ellipse, but the average is 238,000 miles.

Answer 7

It is 384,403 kilometres. We can reach there in 2 and a half months if we travel in Jet Speed.
