The Tarantula Nebula has an [[apparent magnitude]] of 8. Considering its distance of about 49 [[Parsec#Parsecs and kiloparsecs|kpc]]<ref name="seds"/><!-- please calculate light years from parsecs correctly --> (160,000 [[light-year]]s), this is an extremely luminous non-stellar object. Its [[Luminosity#In astronomy|luminosity]] is so great that if it were as close to [[Earth]] as the [[Orion Nebula]], the Tarantula Nebula would cast visible [[Shadow|shadows]].<ref>{{Cite web | url=http://www.noao.edu/news/2011/pr1102.php | title=National Optical Astronomy Observatory Press Release: NEIGHBOR GALAXY CAUGHT STEALING STARS}}</ref> In fact, it is the most active [[starburst region]] known in the [[Local Group]] of [[Galaxy|galaxies]].

It is also one of the [[List of largest nebulae|largest H II regions]] in the [[Local Group]] with an estimated diameter around 200 to 570 [[Parsec|pc]] (650 to 1860 light years),<ref name="seds"/><ref name="Lebouteilleretal2008" /> and also because of its very large size, it is sometimes described as the largest. However, other H II regions such as [[NGC 604]], which is in the [[Triangulum Galaxy]], could be larger.<ref name="Lebouteilleretal2008" /> The nebula resides on the leading edge of the LMC where [[ram pressure]] stripping, and the compression of the [[interstellar medium]] likely resulting from this, is at a maximum.
