if the milky way forms part of the local group what is the other group ? what is the definition of local group

"The Local Group (also called M31 group or the Andromeda group) is the group of galaxies that includes our galaxy, the Milky Way. The group comprises over 30 galaxies, with its gravitational center located somewhere between the Milky Way and the Andromeda Galaxy. The galaxies of the Local Group cover a 10 million light year diameter (see 1 E23 m for distance comparisons). The group belongs to the Virgo Supercluster."

Yes, there are clusters of galaxies. As was stated, the one with the Milky Way galaxy is called the local cluster. Other clusters close by are the Virgo cluster and the Coma cluster; named for the constellation where you can see these galaxies. As you go to larger scales, there are also superclusters of galaxies.

da name uh da galaxy is da Milky Way.. in..

Take into consideration the billions of stars in this galaxy. Then take into consideration the billions of galaxies in the local cluster. Then take into consideration the billions of clusters in the local supercluster. Then take into consideration the billions of superclusters in the local segment of the wall. Then take into consideration the billions of segments in the Great Wall. Then take into consideration the billions of walls in the Universe. It's even possible there's more than one universe! \n\nWhat do you believe? I think there is life out there. But are they sentient and advanced? Maybe. Maybe not.

My opinion is that no one will be able to answer your 'question' because it doesn't make sense in any known language.\n\nHowever, I will try.  Imagine a universe that is divided into two large groups.  \n\nThe members in group A include all 14 of your conditions and some others as well (e.g., 15 blue, 16 tall, etc).\n\nThe members of group B includes everything not included in group A.  \n\nItems 1 to 14 'may' be represented in some subsets of group A.  (Paragraph 1)\n\nNo members of group B will ever be represented in any subset of group A.  (Paragraph 2).

A galaxy is a huge gravitationally bound system of stars, interstellar gas and dust, plasma, and (possibly) unseen dark matter. Typical galaxies contain 10 million to one trillion (107 to 1012) stars, all orbiting a common center of gravity. In addition to single stars and a tenuous interstellar medium, most galaxies contain a large number of multiple star systems and star clusters as well as various types of nebulae. Most galaxies are several thousand to several hundred thousand light years in diameter and are usually separated from one another by distances on the order of millions of light years.\n\nAlthough so-called dark matter appears to account around 90% of the mass of most galaxies, the nature of this unseen components is not well understood. There is some evidence that supermassive black holes may exist at the center of many, if not all, galaxies.\n\nIntergalactic space, the space between galaxies, is filled with a tenuous plasma with an average density less than one atom per cubic meter. There are probably more than a hundred billion (1011) galaxies in the visible universe.

Ok, how about this:\n\nAstronomers estimate that there are at least 70 sextillion (7×10^22) stars in the known universe. That is 230 billion times as many as the 300 billion in our own Milky Way.\n\n(shamelessly stolen from Wikepedia)

Just about all astronomers agree that at the center of our Milky Way Galaxy (and probably at the center of most other galaxies) lies a supermassive black hole. It probably has a mass at least 2-million times that of our Sun, and is approximately 96-million miles in diameter.\n\nThese figures come from careful observation and measurment of the motions of other objects near the galactic center.\n\nThis page has more info, plus a photo ---\nhttp://antwrp.gsfc.nasa.gov/apod/ap021018.html

Circle of Stars.  It is a Yahoo group.

in our galaxy is sirius but in tho whole uneversum WHO KNOWS :P

A galaxy is a swirling collection of stars. our own Milky Way galaxy contains hundreds of billions of stars, of which our sun is only one amongst these billions and billions.\n\nA solar system is just a single sun that has planets revolving around it. A galaxy is made up of billions of such suns. And some scientists believe that as many as 25% of the stars could have planets. That means billions and billions of solar systems in our own galaxy.\n\nHere'a a picture of our closest neighbor, the Andromeda galaxy. It has close to one-trillion stars.\n\nHope this heolps. Cheers\n\nhttp://en.wikipedia.org/wiki/Andromeda_Galaxy

No.\n\nGalaxies are groups of stars and planetary systems.\n\nA single sun (even ours) is not powerful enough to have a galaxy rotate around it (gravitationally speaking).\n\nDoesn't work that way.  We move around inside the galaxy, not the galaxy around us.

The "universe" is filled with galaxies. We're in the milky way. If you buy into star trek, the milky way is divided into four quadrants - the alpha, beta, gamma, and delta.  Earth would be near the border of the Alpha and Beta quadrants.  Then you shrink down further to the star systems - an area around a single or binary sun, which includes any orbiting planets. Then you get to the planet level, divided up by countries, then states, provinces, and municipalities, cities and towns, then finaly, me, you, and all these other people.

Not at all.  The Milky Way, Andromeda and a few other galaxies are in the "local group".  The galaxies in this group orbit around each other.  Just like our planets.  At times some planets will be seen to recede from us and at other times they will be getting closer as all go along in their respective orbits.

what is the group \n\njerms

The galaxy is everything you see at night when you look up in the sky. Stars, planets, moons, asteroids, meteors, comets, or any other terrestrial body. I think there's just one black hole at the middle of the galaxy.

Humans found out that they live in a small living planet in the middle of a very-small galaxy. our galaxy is in the middle of a small super-cluster too. And they dont know more about this.
