NGC 7380 is a young open cluster in Cepheus surrounded in HII region known also as LBN 511 or Sh2-142. The members of the cluster were identified by Baade (1983) on the basis of photometric observations by Moffat (1971). The O-type binary star DH Cep is a member of the cluster which is in its late stage of clearing the surrounding material, and may have triggered the ongoing star formation in neighboring molecular clouds which harbor young stars that are coeval and commoving but not gravitationally bound. This star is located at the center of the cluster (and in the image) and found to be an ionizing star for the emission nebula (Underhill 1969). Recent investigations found 57 variable stars in the cluster region of the NGC 7380 (Lata et al., 2016).

Five emission-line stars (Be type) were found in NGC 7380. The Be stars are defined as rapidly rotating O-, B-, A-type stars of luminosity classes III–V with wide Balmer emission lines (Dimitrov, Kjurkchieva, Ivanov, 2018).
