NGC 7635 (sometimes known as bubble nebula or c 11) is a diffuse nebula visible in the cassiopea constellation towards the cefeo border. M52 is very close to the open storage area and appears in the same field of vision at low magnitudes; Its main feature is a bubble of vacuum surrounded by a nebula, a HII region, at the southern edge of which there is an empty structure, caused by the radiation pressure of a blue, ninth magnitude, central star, whose star wind reaches 2000 km/s; It is a blue giant, who is also responsible for the ionisation of the nebula, which emits its own light. Its distance from the sun is estimated at 11 000 light years.
