NGC 7538, 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.[4] It is located in the Perseus Arm of the Milky Way and is probably part of the Cassiopeia OB2 complex.[3] It is a region of active star formation including several luminous near-IR and far-IR sources.[3] Stars in NGC 7538 are mainly low-mass pre-main-sequence stars.[5]
