What do scientist think all of the stars in the milky way galaxy orbit around?

They orbit around the center of the galaxy due to the galaxy's own gravity. Contrary to popular belief, the Galaxy's central black hole does not have strong enough gravity to hold the entire galaxy together as it accounts for only a tiny fraction of our galaxy's mass.

What are two major ways earth moves in space?
1) Rotation around its axis 2) Orbit around the Sun 3) Orbit around the center of the Milky Way
How does the sun move from a heliocentric perspective?
From the perspective of our solar system, the Sun doesn't move; everything else in the solar system moves around it.In reality, there are NO "fixed points" in the universe; EVERYTHING is moving. The Moon moves around the Earth, the Earth moves around the Sun, the Sun (and our entire solar system) orbit the center of the Milky Way galaxy. All the other galaxies are also moving, and it doesn't make any sense to assume that the Milky Way isn't moving as well - but there is no "stationary spot" in the universe that we can use to measure the Milky Way's movements.
What is significant about the Milky Way galaxy?
For several decades, astronomers believed that the Milky Way galaxy was a spiral galaxy similar to M31 in Andromeda. But recent observations indicate that the Milky Way may actually be a "barred spiral" galaxy.In either event, the Sun and our solar system are about 2/3 of the way out on one of the spiral arms, a very long way from the center of the Milky Way. Which is probably just as well, as recent research indicates that many galaxies including ours may have supermassive black holes at the center. So anywhere near the center of the galaxy would probably be a very nasty place to be!
Is the Earth located in a spiral galaxy called the Milky Way?
The Earth and its parent star, the Sun, are located within the Milky Way galaxy, so named by the inhabitants of Earth. The Milky Way galaxy is believed to be a larger-than-average barred spiral galaxy. There may be as many as 300 billion stars in our Milky Way, maybe many more. The nearest galaxy of such enormous class we have named the Andromeda galaxy. It is roughly 2.5 million light-years distant. But there are two tiny galaxies that orbit our own Milky Way; the Large Magellanic Cloud and the Small Magellanic Cloud. They are named for Ferdinand Magellan, the first white dude from the northern hemisphere to make a big noise about them. The Earth is located in the "Orion arm" of our galaxy, somewhere between half and two-thirds of the way out from its hellish center. In a galaxy thought to be 100,000 light years across, we find ourselves in the lucky "habitable zone" of one of its spiral arms.
How many months can earth can move once?
a million times in one seconds ___________________ There are several distinctive earth movements and this is surely not a complete list. Earth rotates on its axis. Earth also wobbles on its axis, the way a top wobbles when you spin and release it. Earth orbits the sun. Earth's orbit is perturbed by the movements of other planets. Earth's elliptical orbit precesses very slowly (From the perspective of the distant stars, the ellipse of Earth's orbit actually rotates.) Earth and moon revolve around their common center of gravity, called their barycenter. Sometimes massive geological movements (like the quake that initiated the devastating tsunami of a few years ago) will actually change the earth's movement slightly. Earth is following the sun in the sun's vast orbit around the center of the Milky Way. Tidal forces between Earth and Moon are causing Earth's rotation to slow very slightly.
What galaxy is the US in?
The U.S. is on Earth, which is a small planet in orbit around a rather ordinary star in the Milky Way Galaxy.
What is number of moons that orbit the Milky Way?
Moons do not orbit the Milky Way because they Milky Way is a galaxy. But if you are thinking about the amount of moons in the Milky Way total, it is around 1-2million. Probably even more.
How is the entire milky way galaxy moving?
in orbit
How many galaxies did. Earth orbit?
The Earth, along with the Sun and all the other planets orbit around the centre of the Milky Way Galaxy.
What revolves around the Milky Way galaxy?
There are two satellite galaxies, the Greater Magellanic Cloud and the Lesser Magellanic Cloud, which orbit the Milky Way.
Does the sun move or does it stay in one place?
The Sun moves in an orbit around the center of the Milky Way galaxy.
What is orbit of the sun?
The sun is in an enormous orbit around the center of the Milky Way galaxy. It is estimated that it takes between 225 and 250 million years for the sun to make one orbit, called a galactic year. We are traveling around the center of the galaxy at a rate of about 220 km/second, which is .073% of the speed of light.
Why doesn't the sun revolve?
The sun does revolve. It's part of our Galaxy called the Milky Way, and it has its own orbit and trajectory around the centre of the Milky Way.
How long does it take our solar system to complete one orbit around the milky way galaxy?
About 230 million years
Does the Milky Way orbit the sun?
No, the Sun is a part of the Milky Way. Our Solar System orbits around the center of the Milky Way. Our sun goes along with the general spin of the entire Milky Way galaxy, and is positioned rather near the edge. It doesn't orbit it in the sense I think you mean.
Is the Milky Way galaxy earth's galaxy address?
yep, Earth: Milky way galaxy, saggitarius arm, sol, third orbit. :D all you need to do is ask a nerd :P
