The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star. 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 is estimated to be 7,100 - 11,000 ly distant.
Open cluster M52 has an estimated age of 158.5 million years and a mass of 1,200 solar masses at a distance of 4,600 ly.
NGC 7538, The Northern Lagoon Nebula, near the more famous Bubble Nebula, is located in the constellation Cepheus. It is located about 9,100 light-years from Earth. It is home to the biggest yet discovered protostar which is about 300 times the size of the Solar System. It is located in the Perseus Arm of the Milky Way and is probably part of the Cassiopeia OB2 complex. It is a region of active star formation.
