This question as given is probably not what the questioner intended. Galaxies beyond the Milky Way are not interacting orbitally with our sun. If the question is "How long does it take for the Sun to orbit the (center of the) Milky Way?", then the answer is 225 million years.
It Doesn't the Solar System is in the Milky Way Galaxy.
The solar system orbits the galactic center of the Milky Way. The orbital period is estimated to be 225 to 250 million years.
1 million years is 1 Megannum. It takes 250 Megannums to rotate once. Light speed cross? 100.000 (one hundred thousand) to cross. It's unbelievably big but it's less than 2 millionths of space! Less than a pixel on my computers!
The sun is one of hundreds of billion of stars in our galaxy, the Milky Way. The galaxy is composed of gaseous interstellar medium, neutral or ionized, sometimes concentrated into dense gas clouds made up of atoms molecules, and dust. All of the matter -- gas, dust, and stars -- rotate around a central axis perpendicular to the galactic plane. The centrifugal force caused by the rotation balances out the gravitational force, which draw all the matter toward the center.
The mass is located within the circle of the Sun's orbit through the galaxy is about 100 billion times the mass of the Sun. Because the Sun is about average in mass, astronomers have concluded that the galaxy contains about 100 billion stars within its disk.
All stars in the galaxy rotate around a galactic center but not with the same period. Stars at the center have a shorter period than those farther out. The Sun is located in the outer part of the galaxy. The speed of the solar system due to the galactic rotation is about 220 km/s. The disk of stars in the Milky Way is about 100,000 light years across and the sun is located about 30,000 light years from the galaxy's center. Based on a distance of 30,000 light years and a speed of 220 km/s, the Sun's orbit around the center of the Milky Way once every 225 million years. The period of time is called a cosmic year. The Sun has orbited the galaxy, more than 20 times during its 5 billion year lifetime. The motions of the period are studied by measuring the positions of lines in the galaxy spectra.
You don't even know what your'e talking about. The sun doesn't move.
- Ahem! You who gave the above answer. The sun is a star close to the outer rim of the Milky Way Galaxy, which is "Turning" at the rate of approximately one revolution every 225 to 250 million solar years. Keep in mind that a "solar year" here refers to the time it takes the planet earth to circle its star (the sun) one time. So, due to the fact that the sun is part of a system of stars rotating in a circle moving at 168 miles a second, then absolutely the sun is moving!
- The answer therefore to the question is: The sun takes approximately 225 to 250 million years to make on revolution around the milky way.

It is estimated to take about 225 million years
Our sun (and solar system) orbits the Milky Way about once every 200,000,000 years. That is two hundred million years.
250 million years is right for the miky way :) :) :)
We don't know. We don't have enough data yet (hey, we've really only known what a galaxy was for about a hundred years). Current estimates are in the 200-250 million year range.
250 million years
A galaxy is made up of all sorts of matter, including stars. Many stars have object orbiting them, such as planets, asteroids, and even other stars. Solar systems orbit the galactic centre of a galaxy. (Solar systems don't orbit a galaxy, they ARE the galaxy)

Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.
The Earth, along with the Sun and all the other planets orbit around the centre of the Milky Way Galaxy.

Our solar system is estimated to be between 25,000 and 28,000 light years from the centre of our galaxy, the Milkyway.
It is 20 cosmic years old. A cosmic year (for those of you who don't know) is one whole orbit around a Galaxy.
The sun is estimated to be 24,900 ± 1,000 ly from the galactic centre.
The orbit of the sun through our galaxy is thought by many scientists to be almost circular. Since the sun takes about 225 million years to complete one orbit, little proven data is available to support most hypotheses regarding the orbit of the sun.

The Andromeda Galaxy does not orbit a sun as a planet does; it is an immense cloud consisting of as many as 1 trillion stars, each of which can be considered a sun.
There are many black holes in the universe, and they are generally in the very center of a galaxy. Our Galaxy, the Milky Way, has one big black hole in the centre of it.
The Andromeda Galaxy is at a distance of about 2.5 million light-years from Earth; or from the Milky Way.
