how old is the moon?

Answer 1

The theoritical explanation says the moon is 4.5 billion years, just like the earth. .At the time Earth formed 4.5 billion years ago, other smaller planetary bodies were also growing. One of these hit earth late in Earth's growth process, blowing out rocky debris. A fraction of that debris went into orbit around the Earth and aggregated into the moon.

There are some controversies over its given age. Who really knows? "GOD only knows", its real age. Human only got the ability to speculate and make different theories.

Answer 2

First the moon and the earth and all the planets in the solar system was formed about 4.5 billion years ago, the universe is however older by at least 10 billion years. Its estimated that the universe is 13-15 billion years old. The moon formed by a collision with earth and a planet named thea about half the size of earth (the size of mars), the collision was so big that chunks of earth blew out into space. The earth's gravity kept the chunks of rock with in its orbit and that was formed into the moon. This theory is the best supported theory to scientists.

The moon is one of the most essential parts to our existence on earth, the impact that formed the moon jolted the earth so much causing the tilt in its axis which gives us the seasons. With the moon orbiting around the earth it keeps the earth in a stable rotation, without the moon the earth will wobble and we would have very bad weather conditions that will last thousands of years.

Answer 3

Is the moon really old?

Dr Don DeYoung . . . if the earth moon system is as old as evolutionists say, we should have lost our moon long ago.

Astronomer Dr Don DeYoung (Professor of Physics, Grace College, Indiana), in a technical paper presented at the Second International Conference on Creationism in Pittsburgh, USA, in 1990, raises an interesting problem for evolutionists.

There is a huge force of gravity between the earth and moon-some 70 million trillion pounds (that's 70 with another 18 zeroes after it), or 30,000 trillion tonnes (that's 30 with 15 zeroes).

The effect of gravity depends on distance as well as mass, so the pull on the near side of the earth (to the moon) is greater than on the far side. This causes the land and (especially) sea surfaces to bulge in response, as is apparent to us in tides.

Because the presence of the moon over any part of the earth does not cause an immediate bulging response, this slight delay results in a continuous, slight, forward 'pull' on the moon, causing it to spiral slowly outwards, away from the earth. The rate at which the earth-moon distance is presently increasing is actually being measured at about 4 centimetres a year. It would have been even greater in the past.

This immediately raises the question as to whether the earth-moon system could be 4.5 billion years old, as most evolutionists insist. Would we not have lost our moon a long time ago? Using the appropriate differential equation (which takes into account the fact that the force of gravity varies with distance), Dr DeYoung shows that this gives an upper limit of 1.4 billion years.

That is, extrapolating backwards, the moon should have been in physical contact with the earth's surface 'just' 1.4 billion years ago. This is clearly not an age for the moon, but an absolute maximum, given the most favourable evolutionary assumptions. Obviously, in a creation scenario, the moon does not have to begin at the earth's surface and slowly spiral out.* Evolutionist astronomers have not yet satisfactorily answered this, nor the lack of geological evidence that the moon has dramatically receded over the past 4.5 billion years, which would have to be so if their framework was correct.

Footnote
* The moon was probably created close to its present distance from the earth. Over 10,000 years, lunar recession amounts to less than one kilometre.

For the technical reader: since tidal forces are inversely proportional to the cube of the distance, the recession rate (dR/dt) is inversely proportional to the sixth power of the distance. So dR/dt = k/R6, where k is a constant = (present speed: 0.04 m/year) x (present distance: 384,400,000 m)6 = 1.29x1050 m7/year. Integrating this differential equation gives the time to move from Ri to Rf as t = 1/7k(Rf7 - Ri7). For Rf = the present distance and Ri = 0, i.e. the earth and moon touching, t = 1.37 x 109 years.

The September 1998 issue of Creation magazine has a feature article on the moon - its creation and purpose, that will cover this issue and much more. See online version.

Answer 4

The proto-Earth, shortly after its formation from the solar nebula about 4.6 billion years ago, was struck a glancing blow by a body the size of Mars. Prior to the impact, both bodies already had undergone differentiation into core and mantle. The titanic collision ejected a cloud of fragments, which aggregated into a full or partial ring around Earth and then coalesced into a proto-Moon. The ejected matter consisted mainly of mantle material from the colliding body and the proto-Earth, and it experienced enormous heating from the collision. As a result, the proto-Moon that formed was highly depleted in volatiles and relatively depleted in iron (and thus also in siderophiles). Computer modeling of the collision shows that, given the right initial conditions, an orbiting cloud of debris as massive as the Moon could indeed have formed.

Once a proto-Moon was present in the debris cloud, it would have quickly swept up the remaining fragments in a tremendous bombardment. Then, over a period of 100 million years or so, the rate of impacting bodies diminished, although there still occurred occasional collisions with large objects. Perhaps this was the time of the putative magma ocean and the differentiation of the ancient plagioclase-rich crust. After the Moon had cooled and solidified enough to preserve impact scars, it began to retain the huge signatures of basin-forming collisions with asteroid-sized bodies left over from the formation of the solar system. About 3.9 billion years ago, one of these formed the great Imbrium Basin, or Mare Imbrium, and its mountain ramparts. During some period over the next several hundred million years there occurred the long sequence of volcanic events that filled the near-side basins with mare lavas.

Answer 5

The moon as formed when a body the size of Mars collided with the Earth. The cores merged but the mantle was partly ejected. Some of the mantle material fell back and formed the Earth and the rest stayed in orbit and merged to form the moon. So the moon and the earth are the same age about 4.6 million years

Answer 6

The geological epochs of the Moon are defined based on the dating of various significant impact events in the Moon's history. The period of the late heavy bombardment is determined by analysis of craters and Moon rocks. In 2005, a team of scientists from Germany, the United Kingdom, and Switzerland measured
the Moon's age at 4527 ± 10 million years,
which would imply that it was formed only 30 to 50 million years after the origin of the solar system.

It is held that more than 4.5 billion years ago, the surface of the Moon was a liquid magma ocean. Scientists think that one component of lunar rocks, called KREEP (potassium, rare earth elements, and phosphorus), represents the last chemical remnant of that magma ocean.

Answer 7

The Moon is as old as our Galaxy and not like some here have said as old as the Universe, after all the Universe has many Galaxies.!!!

Answer 8

The oldest moon rocks have been dated to 4.5-billion years.

Answer 9

This sounds like the kind of question someone new asks to see how many answers he gets. Obviously, no one knows the answer to this question; we can only hypothesize. We know for a fact that it is up there and it orbits the Earth about once a month and it affects the tides. If you just want to see your question and username on the Internet, try asking how to program your VCR or something.

Answer 10

A sold as the universe, since when the big bang occured. Approx4.5 to 5 billion years ago but no 1 can be certain
