What are the nearby galaxies | Earth, Solar System and Universe.

The closest to the milky way galaxies are which belong to the so-called Local Group. They are easily seen with an amateur telescope. Some, such as Andromeda, and the Magellanic Clouds, can be seen even at a glance.
Orbit some dwarf galaxies around the milky way. In 1994 it was discovered the elliptical dwarf galaxy Sagittarius or SagDEG (Sagittarius Dwarf Elliptical Galaxy in English) to 70,000 light years away, and in 2003 the Galaxy's greatest Can 25,000 light years. They are the closest two discovered so far.

Major nearby galaxies

Andromeda: 2.5 million light years from Earth. It is a giant spiral, twice the size of the milky way. It is the largest of the Local Group Galaxy. It contains hundreds of billions of stars and large number of nebulae. There is a supermassive black hole at its Center. It is very bright and is the most distant object that can be seen with the naked eye. It is estimated that in about 6 billion years, Andromeda and the milky way will collide.
Small and large cloud of Magellan: are two satellite galaxies of the milky way. This means that Via Lactera attracts them with severity, and in the future will be part of it. They are so called because Magellan was the first European Explorer who noted, in the 16th century. The great cloud is 170,000 years light-years away, and the small cloud 210,000 light years. They are irregular, and dwarf galaxies with many nebulae and young stars. In the southern hemisphere are seen with the naked eye, as two white clouds that are isolated from the milky way that crosses the sky.
Triangle: is the third Galaxy in the Local Group, behind Andromeda and the milky way. It is 3 million years light. It is only with telescope. Shaped spiral, similar to our galaxy. It is believed that Andromeda attracts it with its gravity, and could even orbiting around it. In the Galaxy of triangle is the emission nebula largest referred to: NGC 604.
