Large Magellanic Cloud
(somewhat 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
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 termed irregular, but
is currently considered a single-armed spiral galaxy
and a galaxy classification variant
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 (SMC) appear
to contribute to its irregularity. A stream of gas
exists between it and the Small Magellanic Cloud
which is a star-forming region.
