The two Magellanic Clouds (or Nubeculae Magellani) are irregular dwarf galaxies visible from the southern hemisphere, which are members of ourLocal Group and may be orbiting our Milky Way galaxy. Because they both show signs of a bar structure, they are often reclassified as Magellanic spiral galaxies.
The Large Magellanic Cloud and its neighbour and relative, the Small Magellanic Cloud, are conspicuous objects in the southern hemisphere, looking like separated pieces of the Milky Way to the naked eye. Roughly 21° apart in the night sky, the true distance between them is roughly 75,000 light-years. Until the discovery of the Sagittarius Dwarf Elliptical Galaxy in 1994, they were the closest known galaxies to our own. The LMC lies about 160,000 light years away, while the SMC is around 200,000. The LMC is about twice the diameter of the SMC (14,000 ly and 7,000 ly respectively). For comparison, the Milky Way is about 100,000 ly across.
