Description

Sh 2-202 is a large diffuse nebula that appears to surround the ionising star cluster Stock 23, which lies in the direction of the enormous Cam OB1 association. According to a 2003 study, Sh 2-201 contains low mass young stellar objects in a carbon monoxide cloud.

Kharchenko gives a distance of 380 pc and an age of 32,3 million years for Stock 23, She lists HD 237091 (B1:V:nnpe) and HD 20134 (B2.5IV-V) as probable members.

Avedisova places Sh 2-202 in star formation region 140.59+1.91 along with the young stellar objects WB89 474 and [TRC83] 5 as well as the infrared source IRAS 03144+5932.
