Large Magellanic Cloud (LMC)
  ابر ِ بزرگ ِ ماژلان   
Abr-e Bozorg-e Magellan (#)

Fr.: Grand Nuage de Magellan   

The larger of the two Magellanic Clouds dwarf irregular galaxies visible in the southern hemisphere in constellations → Dorado and → Mensa. The LMC spans 8° on the sky, which corresponds to about 20,000 → light-years in diameter, for a distance of some 170,000 light-years. It has a visible mass of about one-tenth that of our own Galaxy. The LMC and its twin, the → Small Magellanic Cloud, are two of our most prominent Galactic neighbours.

large; Magellanic named in honor of Ferdinand Magellan, the Portuguese navigator (c 1480-1521), who undertook the first voyage around the world. The two Clouds were first described by Magellan's chronicler Pigafetta, after leaving the Strait of Magellan in 1520; → cloud.

Abrhâ-ye Magellan

Fr.: Nuage de Magellan   

Two irregular satellite galaxies of our own Galaxy which are visible from the Southern Hemisphere as misty patches in the night sky. → Large Magellanic Cloud; → Small Magellanic Cloud.

Magellanic, named in honor of Ferdinand Magellan, the Portuguese navigator (c. 1480-1521), who undertook the first voyage around the world. The two Clouds were first described by Magellan's chronicler Pigafetta, after leaving the Strait of Magellan in 1520; → cloud.

Small Magellanic Cloud (SMC)
  ابر ِ کوچک ِ ماژلان   
Abr-e Kucak-e Magellan (#)

Fr.: Petit Nuage de Magellan   

An irregular galaxy, the smaller of the two Magellanic Clouds that are satellites of our own Galaxy, lying in the southern constellation → Tucana. The SMC is about 10,000 light-years in diameter and some 200,000 light-years away. It has a visible mass of about 1/50-th that of our Galaxy and 1/10-th of that of the LMC. Its heavy element content is about a factor 5 smaller than that of the Galaxy. The SMC is the third-nearest external galaxy after the → Sagittarius Dwarf Elliptical Galaxy and the → Large Magellanic Cloud (LMC).
