# Distance from Earth to Moon

The Earth has only one natural satellite in the form of the Moon. The distance from Earth to moon can be measured in terms of units like kilometers, miles, light years, etc. It takes about 1.2 seconds for light to travel the distance from the Earth to the moon. Read the following article to know more about the distance between these celestial bodies.

Drifting Away...Very Slowly

According to several researchers, the Moon is gradually moving away from the Earth at a distance of 3.8 cm. per year. In another billion years or so, it will be visibly smaller than the Sun, and Solar eclipses won't be seen by the humans!

What is the Distance from the Earth to the Moon

The moon revolves around Earth in an elliptical orbit. Thus, the distance between both the bodies fluctuates or changes at certain points, and it also varies at the apogee and perigee. The former is a position at which the moon is farthest from the Earth, while the latter is the closest distance. At the perigee, the total distance between the Earth and moon is 363,300 km, while at the apogee, the distance increases up to 405,500 km.

Average Distance to Moon

The average distance between both the bodies in kilometers is 384,400. This accounts for 30 times the Earth's diameter. It would take around 16 days to reach the moon from the Earth at a speed of 1000 km/hr. Passenger jets are capable of attaining this speed.

Distance from Earth to Moon in Meters

The distance between both the bodies, when they are at the nearest (perigee) point is 363,104,000 meters. At apogee, this distance increases up to 405,696,000 meters. The average distance is 384,400,000 meters.

Measuring the Distance in Miles

The average distance from the Earth to the moon in miles is 238,857.

Distance from Earth to Moon in Feet

In some countries, where feet is the common unit of measurement, the following distance facts would prove to be helpful. The distance between the Earth and moon at apogee and perigee is 1,331,020,000 feet and 1,191,290,000 feet, respectively. The average distance is 1,261,000,000 feet.

Distance in Light Years

The distance present between both the celestial bodies in terms of light years is calculated with the help of speed of light in vacuum. As stated earlier, the distance between the moon and Earth is 384,400 km, i.e., 3.844x10^8 m. The speed of light in vacuum is 3x10^8 m/s. The distance from the Earth to the moon in Light years is therefore, calculated by the formula,

In this case, 1.2 seconds is the distance from Earth to moon in light seconds, and 3.8^-8 is the distance in light years.

**Time =**Distance/SpeedIn this case, 1.2 seconds is the distance from Earth to moon in light seconds, and 3.8^-8 is the distance in light years.
