They would still pull on the Earth, the Sun, and our galaxy. But their individual gravities would be nearly indistinguishable as part of the overall gravity of the parent galaxy. The variations in our gravity due to other stars is negligible compared to that of the Earth, the Sun, and objects within the solar system. But the combined force of many stars are what keep the galaxy from flying apart, and what draws galaxies toward each other.
The Earth, being our closest large mass, exerts many times the pull on earthly objects as the distant Sun. (Gravity is inversely proportional to distance from the center of mass.)
That's exactly what actually happens. There's a mutual gravitational force between
every pair of objects, whether they're two ants on the same apple or two stars in
different galaxies. For that matter, an ant on earth and a star in another galaxy are
also attracted toward each other by mutual gravitational forces. Just look around,
and you can see the effects of all of these forces.
False
Because they are in another galaxy and and they recognise the symbols of the of the stargate differently in the Pegasus galaxy.
A grand design spiral galaxy (like Whirlpool Galaxy) has prominent and well defined spiral arms, whereas a flocculent galaxy (like Sunflower Galaxy) has short segments of spiral structure, "fluffy" in appearance, but without the dramatic well defined spiral arms of a grand design spiral.
Here's one: White dwarf star. Here's another: Whirlpool galaxy (M51).
It means that most of the galaxy in the Star Wars universe has to do with the war between the Republic and the CIS.
It would be inactive, thus considered a "pure galaxy". This "pure galaxy" is alsoconsidered to be an elliptical galaxy (E7). It would be inactive because no aliengravitational forces have affected the relatively stable system.===============================Note: When you copy a question straight off of your homework assignment anddump it onto a public website hoping that someone else will answer it for you, it'sconsidered poor form to also copy the number of the question along with it.
True
True
Galaxies do exert significant gravitational attraction on other galaxies. For example, the Greater and the Lesser Magellanic Clouds are galaxies that orbit our own galaxy, the Milky Way. In that sense, the stars in one galaxy do have a gravitational interaction with those in other galaxies. Of course, the more distant galaxies have correspondingly less gravitational interaction with ours.
No. It's the mutual gravitational force between it and the earth that keeps a satellitein a closed orbit, instead of flying off away from earth in a straight line.Technically, there's no such thing as "outside of" the gravitational force of anything.We can calculate the gravitational force between a star in a distant galaxy and the earth.In fact, we can calculate the gravitational force between a star in a distant galaxy and you.The force is pretty small, but it's there.
A satellite galaxy is one that revolves around another galaxy.
true
There is no limit, and it never ends. The formula to calculate the gravitational force at any distance has no limit in it. The force of the gravitational attraction between the earth and another object can be calculated even if the other object is in another galaxy. Of course, the farther apart two masses are, the smaller the gravitational force between them is. So when you're far from the earth, there's probably something else nearby that attracts you with a stronger gravitational force than the earth does. But no matter how far away you are, and how weak it gets, the earth's gravitational force never ends.
The farther away another galaxy is from our solar system the less effect that the gravitational pull will have on that galaxy.Thus allowing the other galaxy to travel at a faster rate.
By gravitational pull from the galaxy
Massive means there is a lot of mass - and gravitational attraction depends on the amount of mass. The amount of gravitational attraction also depends on the distance - i.e., the effect will be less at larger distances. The gravitational attraction between galaxies is strong enough to make galaxies in a galaxy cluster stay together - for example, in our Local Group.
The force of gravitational attraction between two masses is never zero. There is a force of gravitational attraction between a hair on your head and the smallest moon in the farthest galaxy. The force may be too small to measure, but it's never zero.
A point where the center does not have gravitational pull... once things stop orbiting thats it for the galaxy
