Sh2-187, LDN 1314, 1316, 1317, 1319, 1322, 1323, 1324
Sh2-187, located in the constellation Cassiopeia, is a small but active star-forming region approximately 4,700 light-years (1,440 parsecs) away. It is part of a larger molecular complex, with a visible section surrounded by a massive envelope of neutral hydrogen, weighing around 7,600 solar masses.
The region contains high-velocity molecular outflows and numerous infrared sources, including the powerful emitters S 187 IRS and IRAS 01202+6133, which indicate ongoing star formation. With an estimated age of 100,000 to 200,000 years, Sh2-187 is a relatively young and dynamic stellar nursery, surrounden by some dark nebulae (LDN 1314, 1316, 1317, 1319, 1322, 1323, 1324).
