NGC 2175

NGC 2175(也稱為OCL 476Cr 84)是嵌入在獵戶座的一個擴散星雲內的疏散星團。它早在1654年之前就被Giovanni Batista Hodierna英语Giovanni Batista Hodierna發現,並且在1857年被 卡爾·克里斯蒂安·布魯恩斯再度獨立發現。NGC 2175與地球的距離大約是6,350光年

環繞著它的星雲是沙普利斯亮星雲表的Sh 2-252。

NGC 2174和NGC 2175這兩個識別碼在使用上經常混淆不清。可能適用於整個星雲,或是最亮的結,或是它所包含的星團。伯納姆的天體手冊英语Celestial Handbook 以2174/2175列出整個星雲,但沒有提到星團[1]。NGC專案(對原始描述的註解工作)指定NGC 2174是顯著的結 06 h  09 m  23.7s, + 20 °  39 ′  34″,和NGC 2175 是整個星雲和星團的擴展[2]。Simbad使用NGC 2174是星雲,而NGC 2175是星團[3] [4]
