Why doesn't the moons gravity pull extend all the way through space and affect astronauts?

Answer 1

The Moon's gravity DOES extend all the way through space. An astronaut in orbit around the Earth, at 200 km above the Earth (for example), is about 377,800 km from the Moon. If you work out the equations, that means the Moon's gravity pull on the astronaut is about 20,000 times WEAKER than the Earth's gravity pull.

Answer 2

The gravity of the moon produces a bulge (drag) on our oceans which causes high and low tides.

It also pulls the astronauts but because of the earths gravity being much stronger, the astronauts stay near the earth.

Answer 3

ok, that could be a very solid question. 2 section answer, the place the two areas are not consistent, simply by fact we don't yet have a solid concept of quantum gravity: a million) In cutting-ingredient physics, the vacuum isn't "not something". It has fields, and the fields have 0-ingredient capability. It additionally has "darkish capability", which may be with regard to the 0-ingredient capability in techniques that we nevertheless don't understand. How this pertains to gravity continues to be very poorly understood, and is the situation of modern-day, ongoing learn. 2) In classical time-honored Relativity, area is definitely particularly empty (that could be a classical concept). opposite to many popularizations of time-honored Relativity, in the formal concept there's no "fabrics of area". What there are, are "spacetime activities", confident factors in spacetime, like a firecracker going off at a particular place and time. those factors are separated with the aid of distances in spacetime that are nicely defined. The community of such distances describe a geometry, and that geometry is, regularly, non-Euclidean. that is as though there have been a history, curved manifold which substitute right into a "fabrics of area", however the theory would not rely in one among those ingredient genuinely present. each thing you could degree relies upon basically on the community of distances between spacetime activities, not on any assets of the vacuum. There would not ought to be something in between the spacetime activities for the geometry to be "curved". the theory facilitates an precise calculation of the effects of gravity, based on the effect of mass on the geometric manifold, however the manifold is merely a manner of representing the courting between spacetime activities and would not inevitably have any certainty in itself.

Answer 4

It does extend to every corner of the universe!!
But the farther away from the moon you get, the less effect gravity has. By the time you get to earth, there is just enough attraction to make the oceans move a bit (tides).

Answer 5

It does... but only a very small amount.

When the astronauts are in orbit they are said to be in a "micro gravity environment". There are gravitational effects from all "matter" in the nearby vicinity... including the mass of the spacecraft, itself.

The main gravitational effect is from Earth (if they're in Earth orbit) because Earth is so massive in comparison to the other influences and the distances involved.

Answer 6

It does extend. It is called micro gravity. It has very little or no effect on something as small as an astronaut.

Answer 7

it does. in fact everything in the universe has its own "force of gravity" even a pen. its just so small it aint worth noticing. astrology, the belief that the planets effect your life is based on the gravitational pull o you when you were born. ive experimented with this and found out the doctor delivering you has a greater effect of gravity on you than the planets millions of miles away. makes ya think!!!

Answer 8

It extends everywhere but it's miniscule near the surface of the earth where the astronauts travel.

Answer 9

Becasue the moons mass isn't big enough to have enough gravitational pull on anything else but planet earth everything else is just to far away

Answer 10

It does.
