About 25,000 light years from us,
It is the Canis major dwarf galaxy. It is 25,000 light years away from the sun.
Andromeda galaxy is approximately 2.5 million light years from the Milky Way however there is a dwarf galaxy discovered in 2003 named Canis Major that appears to be in the process of being absorbed by the Milky Way and Canis Major is only 42000 light years from our galactic core but only 25000 light years from Earth.
The closest irregular galaxy to us is the Large Magellanic Cloud, which is located around 163,000 light-years away from Earth. It is a satellite galaxy of the Milky Way and can be seen with the naked eye from the southern hemisphere.
The nearest galaxy of similar size to the Milky Way is the Andromeda galaxy. That's about 2.5 million light years away. We do have nearer neighbors, usually called "dwarf galaxies". The nearest is the Canis Major dwarf, which is only about 25,000 light years from Earth. The famous "Magellanic Clouds" are a bit more than 150,000 light years away.
The nearest neighbor galaxy to the Milky Way is the Andromeda Galaxy, also known as M31. It is located about 2.537 million light-years away from Earth and is part of the Local Group of galaxies. Andromeda is on a collision course with the Milky Way and will eventually merge with our galaxy in about 4.5 billion years.
Perhaps you are referring to quasars. Quasars are (galaxies with) extremely active galactic nuclei.Otherwise, as far as we know, many of the larger galaxies seem to contain a supermassive black hole in the center. If by black hole you are referring to standard black hole, not a supermassive, chances are all galaxies have quite a few. Within the local group of galaxies (Our cluster), the brightest galaxy as it appears from Earth is the Canis Major dwarf galaxy at 25,000 lightyears away. For galaxies not within our cluster, the brightest would be Markarian 231 at about 600,000,000 lightyears away.Comparing apparent magnitude. Canis Major's apparent magnitude (Little "m") is approximately 23.3m where Markarian 231 is about 13.8m yet the galaxy is 2,400,000% further away than Canis Major. An interesting side note about this galaxy is that it's supermassive blackhole is accompanied by a large quasar.
Milky Way Galaxy - Our GalaxyOmega Centauri - former galaxy - 0.0183 million light years awayCanis Major Dwarf - 0.025 million light years awayVirgo Stellar Stream - 0.03 million light years awaySagittarius Dwarf Elliptical Galaxy - 0.81 million light years awayLarge Magellanic Cloud - 0.163 million light years awayAndromeda Galaxy - Largest - 2.5 million miles away.The Canis Major Dwarf Galaxy orbits the Milky Way at 42,000 light years from the galactic center. The Sagittarius Dwarf Elliptical Galaxy orbits at 50,000 light years. The Large and Small Magellanic Clouds are also very close to the Milky Way, but there is some debate over whether they are "orbiting" the larger galaxy. However, orbiting or not, they are still considered "satellites" of the Milky Way. All of these galaxies are very small compared to the Milky Way and most are irregular in shape, all of them lacking the spiral structure normally associated with a well-organized galaxy. The Phoenix Dwarf Galaxy is 1.44 million light years from the center of the Milky Way, and NGC 6822 (aka Barnard's Galaxy) is 1.6 million light years away.See related link for more information.
The Pegasus Dwarf Irregular Galaxy is approximately 3 million light years away. The Pegasus Dwarf Spheroidal Galaxy is approximately 2.7 million light years away.
Dwarf to giant then to supergiant Dwarf to giant then to supergiant the Largest Star in the Galaxy is VY Canis Majoris which sits in Canis Majoris or the greater dog. Along with the brightest star Sirius. There are follow up stars such as VW Cephi A (if my spelling is correct) and WOH G64. There are many others the are along this size. There are to many stars in our universe to start from beginning to end. The sun is NOT the biggest star in our universe, as of known the Eta Carinae is the biggest star yet.,acualy vy canis majoris is the largest star by far
Canis Maioris is a constellation, not a place in the galaxy. A constellation is basically a direction in space - it starts right here, and goes all the way to infinity (or however far the Universe goes).
A galaxy is much larger than a white dwarf star. Galaxies can contain billions to trillions of stars, along with gas, dust, and dark matter, and can measure thousands of light-years across. In comparison, a white dwarf star is a small, dense remnant of a star that is roughly the size of Earth but with a mass similar to that of the Sun.
HD 47536 is located approximately 396 light-years away in the constellation of Canis Major
