Is it true that the moon will eventually escape from the earth's gravity?

Answer 1

Yes it is! The moon is in an outward decaying orbit. It actually moves approximately 1 inch away from the earth each year. That is because it's orbit is fractionally to fast for a stable orbit. Don't worry, it will still be there for our lfe time.

Answer 2

Raymond's answer is partly right, but there is more.

The tides will gradually slow the earth and drive the moon farther away, until the two become gravitationally locked. Lunar tides will end. Before the logical conclusion of this dance, both earth and moon may be engulfed by the expanding sun.

If the earth and moon do survive, however, their celestial dance will not be over. As the earth continues to revolve around the sun, there are still going to be tides, solar tides, the same phenomenon that today causes spring tides and neap tides.

The solar tides will continue to slow the earth down. As our grows ever so gradually longer, the angular momentum lost to the earth will be transferred to the moon, forcing the moon to revolve around the earth faster.

The moon will spiral back closer to the earth as a result. The moon can never be lost to the earth, except conceivably as the result of a near-miss collision with some other large celestial body.

Answer 3

no.

The Moon is presently receding from us at a rate of about 4 cm (a little over an inch) per year. This is due to the tidal effect that the Moon has on Earth.

Moon raises tidal bulges on Earth. Bulges drag on ocean floors (especially in the Irish Sea) and get pulled Eastward of the line joining the centre of Moon and Earth.

Bulges are large enough to influence Earth's gravity field and they 'pull' the Moon slightly ahead (i.e., slightly faster) on its orbit. The result is that the Moon's orbital energy increases (= the Moon climbs a tiny bit away to a higher orbit) and the Earth's rotation slows down.

As the Moon moves away, the tidal effect diminishes so that the transfer of energy has a slower rate. Eventually, once the Earth has a rotation rate (spin) equal to the orbital period of the Moon (i.e., when the Earth presents the same face to the Moon), in approximately 8 or 9 billion years, the effect would stop completely.

At the time, the Moon would still be a satellite of Earth.

Except that in the meantime:
- the Sun will have gone through its red giant phase (5 billion years from now) and it is not clear whether Earth will survive that (probability is that we won't);
- our Galaxy and the Andromeda galaxy will have collided (4 billion years) and it is not clear if our solar system will survive that (although the probability is high that we will survive).

Answer 4

there is largely a million organic satellite tv for pc of Earth, the Moon (additionally noted as Luna). Cruithne is a quasi-satellite tv for pc. It has an orbit that just about coincides with Earth's, in spite of the shown fact that it orbits the sunlight, not Earth. as a result, this is not a real satellite tv for pc of Earth.

Answer 5

Note that the recession of the moon is good evidence that the moon (& earth) are not as old as cliamed by secular evolutionists.

Friction by the tides is slowing the earth’s rotation, so the length of a day is increasing by 0.002 seconds per century. This means that the earth is losing angular momentum.7 The Law of Conservation of Angular Momentum says that the angular momentum the earth loses must be gained by the moon. Thus the moon is slowly receding from Earth at about 4 cm (1½ inches) per year, and the rate would have been greater in the past. The moon could never have been closer than 18,400 km (11,500 miles), known as the Roche Limit, because Earth’s tidal forces (i.e., the result of different gravitational forces on different parts of the moon) would have shattered it. But even if the moon had started receding from being in contact with the earth, it would have taken only 1.37 billion years to reach its present distance.8 NB: this is the maximum possible age — far too young for evolution (and much younger than the radiometric ‘dates’ assigned to moon rocks) — not the actual age.

Answer 6

Raymond has the only correct answer. There is not enough angular momentum in the Earth's rotation to completely remove the moon from orbit. You can calculate it yourself with the formulas from physics class.

Answer 7

The moon is moving 3 cm away from Earth every year.

Answer 8

Yes. At one time the sun was completely hidden during a solar eclipse, as the moon moves further away from earth it will appear smaller and smaller so the appearance of an eclipse will change too.

Answer 9

I think ur question is not clear,why did u get such a dout,plz mension it clearly,do u mean after a longer time it may happen then it is no since all the universe is again going to again combine ,according to the concept big bang theory

Answer 10

Yes, it will, but don't hold your breath. It will take many millions of years to happen.
