How many planets does Orion consist of?

Orion is mainly composed of seven stars, all bright. Orion is not the largest, ranking 26th in the whole day, but it is the most dazzling constellation among the 88 constellations in the whole day (because its members are bright).

The alpha star of Orion, Betelgeuse, is located in the upper left corner of Orion. It is the main star of Orion, which is very conspicuous. The brightness of the whole sky ranks tenth, the apparent magnitude is 0.58, and it is 640 light years away from us. Betelgeuse is a red Supergiant star with a spectrum of M2Ia. It is one of the largest stars. Its diameter can accommodate 1 179 suns, but its mass is only 1 1 times that of the sun. It is at the end of its life and is expected to die out in the form of supernova explosion soon. Recently, its brightness has dropped sharply, and now it has dropped to 65438.

Betelgeuse is the brightest star in Orion with an apparent magnitude of 0. 12. It is located at the lower right of Orion, ranking seventh in brightness in the whole day, 863 light years away from us. Its essence is a blue Supergiant star with a spectrum of B8Ia. Betelgeuse is huge, its diameter is 78 times that of the sun, and its mass is 2 1 times that of the sun. Its powerful radiation can destroy all its planets.

Gamma star Betelgeuse is on the lower right of Betelgeuse and on the upper right of Orion. It is the third bright star in this constellation with an apparent magnitude of 1.6. It is a giant star with a spectrum of B2Ⅲ, with a diameter of 5.75 times that of the sun and a mass of 8.5 times that of the sun. Its hydrogen fuel is about to run out, and helium fusion will begin in millions of years.

In the middle of Orion, there is a belt consisting of three stars. They are called Fu Lushou Samsung. "When the sun shines high, good luck comes." In other words, every Spring Festival, Samsung will be at the top of the sky. From left to right, these three stars are Betelgeuse, Betelgeuse and Akisaka. Their quality is really outstanding. They are the largest1100000 in the star world.

Betelgeuse (Orion zeta) has an apparent magnitude of 2.05, etc. 1, 200 light years away, Betelgeuse is a high-quality late O-type Supergiant star. Its spectrum is O9.7Iab, its mass is as high as 33 times that of the sun, and its diameter can accommodate 20 suns.

Betelgeuse (Orion ε) is a star in the middle of the Orion belt, 2000 light years away from us, with an apparent magnitude of 1.69, which is very bright. Betelgeuse is a B-shaped blue Supergiant star with 40 times the mass of the sun and a radiation of 570,000.

Delta star Orion, mintaka, apparent magnitude 2.23, is the darkest of the seven stars and the rightmost of the three stars, but the radiation is not low. You know, it is an O-shaped Supergiant star similar to Betelgeuse, and its spectrum is O9.5Ia! Its mass is 24.5 times that of the sun and its diameter is 16.5 times that of the sun.

Finally, I want to introduce Betelgeuse (κ star), which is the left foot of Orion, on the left side of Betelgeuse, with an apparent magnitude of 2.05. Betelgeuse is a B-shaped blue Supergiant star, its mass is 15 times that of the sun, and its radius is 22.5 times that of the sun. It can be seen that its hydrogen has been exhausted and it has undergone a lot of evolution. Millions of years later, it will swell into a red Supergiant star.

This is a brief introduction of the seven bright stars of Orion. You got it?
