What stars does Orion consist of?

The four stars α, γ, β and κ in the constellation form a quadrilateral, and at its center, the three stars δ, ε and ζ are arranged in a straight line. These are the seven brightest stars in Orion, among which α and β are 1m, and the rest are 2m stars. There are so many bright stars in a constellation, and the arrangement is so regular and magnificent. No wonder, all over the world, it is a symbol of strength, tenacity and success, and people always compare it to gods, warriors, superman and heroes.

The brightest star in Orion is alpha star, which is the sixth brightest star in the whole day. Orion β is the eighth bright star in the whole day. Every year 1 the end of February, at 8: 00 pm, the three stars of Orion are high in the southern sky, so there is a folk saying that "the three stars are shining high and the New Year is coming".

Orion's most famous celestial body should be the Big Nebula. It is located in the south of Samsung, with an apparent magnitude of 4m. It looks like a white fog, which is very easy to identify.

There is also a nebula near Orion zeta. There are no stars nearby to illuminate it, and no one provides it with ultraviolet rays to make it shine. It only blocks the light from a bright nebula, so that we can see its outline-the shape of a horse's head, so this nebula is also called the Horsehead Nebula. It is a typical dark nebula.
