Why do stars not move?

Answer 1

Plasma an the physics behind it are the reason, those exact physics are still not clear to many exactly as we are lead fo believe. Master plasma in a safe way it would be reasonable to assume it would be a closely guarded secret as was the first a-bomb or super sonic flight or the first U2 dragon lady, SR-71 Black Bird, Covair Kinfish, F-117 Nighthawk, F-22 Raptor and other then YB, YF, X and YS programs. Example the X-15 program data was used for the space shuttle program that could not have existed of not for the X-15 . The folks running these programs like these are un rewarded jeros as wel as everyone that work for them

Answer 2

During the majority of a star's lifespan, the internal pressure created by its fusion process keeps it from collapsing in on itself. At the end of the star's life, however, the elements fueling the fusion process have been consumed, and gravity will overcome the star's internal pressure.

Answer 3

Stars appear to not move in the night sky because of their vast distance from Earth. The motion of stars is not detectable to the naked eye over short periods of time due to this immense distance. However, stars do have their own movements, including orbiting around the center of the galaxy.

Answer 4

Actually they do - they move all the time. However, a typical visible star is in the order of 100,000 - 1,000,000 times farther than the planets in our Solar System, so it takes much longer for any movement to be noticeable.

Answer 5

The gravitational attraction of the combined mass of the galaxy. Since it has been calculated that the combined mass of all the stars is not large enough by far to explain the observed rotation, there must be some invisible matter of unknown composition (called "dark matter") that has several times the mass of the known matter.

Answer 6

The gravitational pull is counteracted by two forces: the gas pressure, and the radiation pressure. Gas pressure alone is not enough, so when the star stops producing energy, it will indeed collapse - into a white dwarf, a neutron star, or a black hole, depending on its mass.

Answer 7

Gravity holds the stars at certaindistances and holds them in place. also there are many stars that are held in different positions in our galaxy.

No one star is in rest! All of them are moving on certain orbits round the center of Galaxy in the gravitational field of other stars. From for huge distance of stars from the earth, their displacement we do not notice. Distortions of forms of constellations are appreciable well for thousand years.

Answer 8

The sun is a star, and it is a nuclear fusion machine. Nuclear fusion on this scale produces an enormous quantity of energy, and all that energy does not want to stay in one place. The great amount of energy the sun produces wants to cause the sun to "blow up" and fly apart, but the massive gravity of the star prevents that.

A star could be looked at as a study in equilibrium. Gravity is trying to crush the whole thing together, and the massive energies produced by fusion is attempting to cause the whole thing to be blown off into space. So it is from the time a star begins to "burn" until it dies, by whatever means.

Answer 9

Well, instead of going into a long-winded explanation that would be sure

to confuse you, we just want to give you a simple fact to think about:

The sun is a star. Compared to all the other stars, the sun is pretty close to us.

But for right now, forget about the sun, and let's talk about the other stars.

They are very far away. Too far for us to understand, or even to imagine.

We want to give you this one little fact about the nearest star:

If the nearest star decided it wanted to crash into the earth, and it started speeding

our way at 1 million miles an hour . . . it would take almost 3,000 years to get here.

And that's the nearest star to us.

Answer 10

The universe is expanding. This means that the stars are constantly moving. That motion is enough to counteract the force of gravity which all bodies exert on all other bodies in the universe. Just as the motion of the planets around the sun is enough to keep them 'up' in space, so the motion of the stars (other suns) is enough to keep them 'up'.
