The Large Magellanic Cloud (LMC), also called Nubecula Major, is a satellite galaxy of the Milky Way. At a distance of around 50 kiloparsecs (160 kly), the LMC is the second- or third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal (c. 16 kpc (52 kly) away) and the possible dwarf irregular galaxy called the Canis Major Overdensity. Based on the D25 isophote at the B-band (445 nm wavelength of light), the Large Magellanic Cloud is about 9.86 kpc (32.2 kly… WebThe center panel shows the measured positions and the right panel has the proper motion removed to better show the parallax effect.
