# How far is the Moon from the Earth?

# About how far away is the Moon in terms of Earth radii?

About 60 Earth radii.

# Is the moon at apogee near or far from the earth?

Its far, apo means up/away

# If the moon were twice as far from the earth as it is now the gravitational force it exert on the earth would be?

half its present value

# How far is the moon from earth in light years?

The average distance to the Moon is 384,399 kilometres = 4.06318742 Ă— 10-8 light years (Note the minus) The moon is only a tiny fraction of one light year from earth. It ta…kes light from the sun eight minutes to reach earth, and the moon is much closer to earth than the sun. Measuring such a small distance in light years is possible but impractical. ======= The moon is roughly 1.27 light seconds from the earth. (rounded) 1.27 light seconds is the same as 0.0000000406 light year. (rounded)

# How far does the moon move away from the earth each year why?

As a result of the conservation of angular momentum, the slowing of Earth's rotation is accompanied by an increase of the mean Earth-Moon distance of about 3.8 m per century, …or 3.8 cm per year.

# How far does the Moon move away from the Earth?

the Moon moves about 3.8 cm away from the earth each year

# How far has the Moon moved from the Earth?

The Moon is slowly moving away from the Earth in its orbit. The average change is currently about 38 mm per year, or about 38 km every million years.

# When the moon is at apogee how far away from the earth?

252,088 miles

# Why is the moon so far from the earth?

The moon is far away because if it were to close then the gravity from earth would pull it in to use amd destroy the earth. And the moons graviy pull that it has on earth alre…ady affects the ocean, for example at night the oceans level is higher. hope this help and if anyone has a better explaination then please post.

# How far does the moon travel in one orbit around the earth?

A rough calculation: Mean radius = 238,000 miles Circumference = 2 pi R = 476,000 pi = 1.495 million miles . Verrrry interesting ! If you could straighten out the… moon's whole orbit around the earth, it would span only about 1.6 percent of the distance to the sun !

# How far away is earth to the moon in cm?

1. Dist from Earth to Moon = 382500 Km 2. 382500 x 1000 = 382500000 m 3. 382500000 x 100 = 38250000000 cm

# How far apart are the sun earth moon?

The Sun and the Earth are 149.6 million kilometers apart. The Earth and the Moon are 384,400 kilometers apart.

# How far is it to the moon and back to the earth?

About half a million miles. Of course, a trip in a spaceship wouldn't be on a straight line course, so it would actually travel many times that far.

# How far is earth from the moon and the sun?

1. Earth-Moon distance From Earth Center (EC) to Moon in km : Moon is a natural satellite of earth. For any satellite, to predict its instantaneous distance from ear…th requires its ephemeris data which indicates the satellite's orbital parameters known as Keplerian elements. The ephemeris data acquired on a particular day, called epoch, is applied as input to satellite tracking software for accurate predictions of satellite position in next few days. Thereafter a new set of Keplerian elements are acquired. The computed values of Distances from Earth Centre (EC) to Moon in km at Epoch (UT year = 2014, month = 5, day = 23, hr = 3, min = 59, sec = 20.61457) and at four other specific instances of Year = 2013 while Moon was at apogee, perigee and crossing over earth equator at ascending & descending nodes were as follows : GMT Time (Y M D h m s) - - -Moon Position (instance) - - - - Earth-Moon Distance (km) 2014:05:23:03:59:20 - - - - - - Epoch - - - - - - - - - - - - - - - - - - - 368644.28 2014:06:02:18:36:48 - - - - - - Apogee - - - - - - - - - - - - - - - - - -402802.27 2014:06:06:10:09:59 - - - - - - Earth Equator - - - - - - - - - - - - - 396714.18 2014:06:16:10:28:23 - - - - - - Perigee - - - - - - - - - - - - - -- - - - -363564.67 2014:06:19:11:12:09 - - - - - - Earth Equator - - - - - - - - - - - - - 368681.22 2014:06:30:02:19:58 - - - - - - Apogee - - - - - - - - - - - - - - - - - - 402802.04 2014:07:03:17:53:08 - - - - - - Earth Equator - - - - - - - - - - - - - 396808.49 2014:07:13:18:11:34 - - - - - - Perigee - - - - - - - - - - - - - - - - - - 363565.04 2014:07:16:18:55:18 - - - - - - Earth Equator - - - - - - - - - - - - - 368586.79 It is clear as how much the distance of Moon from Earth Centre vary. Since epoch the minimum distance was 363564.67 km and the maximum distance was 402802.27 km. 2. Earth-Sun distance From Earth Centre to Sun Centre (EC to ES) in km : Earth Revolves around Sun in a counter clockwise direction. The earth's orbit around the sun is not a circle, it is slightly elliptical. Therefore, the distance between Earth and Sun varies throughout the year. To predict Earth-Sun distance any instant of time, we must know the position of Earth and Sun at same instant on Celestial Sphere. For computing the position of Earth on celestial sphere at any instant, we first need to compute position of Sun on celestial sphere. That provides many inputs required to compute position of Earth at same instant on celestial sphere. The computed values of Distances from Earth Centre (EC) to Sun Centre (SC) in km at Standard Epoch JD2000 and at six other specific instances of Year = 2013 while Earth was at Perihelion, Vernal equinox, Summer solstice, Aphelion, Autumnal equinox, Winter solstice were as follows : GMT Time (Y M D h m s) - - -Earth Position (instance) - - - Earth-Sun Distance (km) 2000:01:01:12:00:00 - - - - - - Standard Epoch - - - - - - - - - - 147101196.66164 2013:01:03:09:11:56 - - - - - - Perihelion - - - - - - - - - - - - - - -147098790.67105 2013:03:20:11:02:09 - - - - - - Vernal equinox - - - - - - - - - - -148990030.62423 2013:06:21:05:01:19 - - - - - - Summer solstice - - - - - - - - - -152030553.38444 2013:07:05:00:18:52 - - - - - - Aphelion - - - - - - - - - - - - - - - - 152098441.95238 2013:09:22:20:45:38 - - - - - - Autumnal equinox - - - - - - - - 150128324.53014 2013:12:21:17:10:03 - - - - - - Winter solstice - - - - - - - - - - - 147162430.96729 It is clear that the distance of Earth Centre (EC) from Sun Centre (SC) vary throughout the year. In the Year 2013 minimum distance was 147098790.67105 km and maximum distance was 152098441.95238 km. Note : All these values are computed using the Orbital Mechanics - Model & Simulation Software OM-MSS.
