Sh2-132, also known as the Lion Nebula, is an emission nebula located in the constellation Cepheus. It is about 10,000 light - years away from Earth.
The nebula gets its energy from two massive stars, each with a mass over 20 times greater than our Sun. It is formed by expanded shells of ionized gas. The angular size of Sh2-132 is slightly larger than that of the full moon.
The main stellar source of Sh2-132 is a double - binary system that includes the Wolf - Rayet star WR153ab. Besides, it also contains an O8.5V star and about ten B - class stars. The interaction between the massive stars and the interstellar medium in Sh2-132 leads to the formation of Hii regions, interstellar bubbles, and new stars.
