Description

NGC 7635, also known as the Bubble NebulaSharpless 162, or Caldwell 11, is an H II regionemission nebula in the constellation Cassiopeia. It lies close to the direction of the open clusterMessier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575 (BD+60°2522). The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel. The star BD+60°2522 is thought to have a mass of about 44 M☉.
