Large Magellanic Cloud

(LMC)
(irregular satellite galaxy of the Milky Way)

The Large Magellanic Cloud (LMC) is a Satellite Galaxy orbiting the Milky Way, about 160,000 light-years away. It is the third closest Galaxy, after the Sagittarius Dwarf Elliptical Galaxy and Canis Major Dwarf Galaxy. Its mass is about 10 billion solar masses, about 1/100 as massive as the Milky Way. Its diameter is 14,000 light-years and it the fourth largest galaxy in the Local Group after Andromeda, the Milky Way, and the Triangulum Galaxy.

It was formerly classified as irregular, but is currently considered a single-armed Spiral Galaxy and a Galaxy Classification has been invented for its morphology: Magellanic Spiral Galaxy ("Magellanic" indicated by an appended lower-case "m").

Interaction with the Milky Way and the Small Magellanic Cloud appear to contribute to its irregularity. A stream of gas exists between it and the Small Magellanic Cloud which is a Star-Forming Region.

Characteristics:
