The brightest star in Orion is beta star, with an apparent magnitude of 0. 12, ranking seventh among all bright stars in the whole day, with an absolute magnitude of -7. 1 and a surface temperature of 12000. Alpha Orion, the ninth brightest star in the whole day, Latin for Betelgeuse, with a brightness of 0.06-0.75 and a period of 5.5 years, is an irregular variable star.

The young, massive and high-temperature stars in the nebula emit strong radiation, and ionized hydrogen emits light, forming a spectacular scene.
