NGC 1931
NGC 1931, found in the constellation Auriga has been referred to as a "miniature version of the Orion Nebula", as it shares some of the same characteristics. It is a mixed emission-reflection nebula, and contains a smaller version of the Trapezium in its hot young star cluster centered in the emission nebula. The entire cluster/nebula complex is only about 3 arcmin〔(NGC 1931 @ SEDS NGC objects pages )〕 in size. The distance from earth is estimated at about 7000 light years. The nebula is Sharpless catalog Sh 2-237. ==References==
