I heard that there is a constellation called Beiluo Shimen, which is very artistic. Who can introduce it? Is there a South Roche school?

Beiluoshimen (the alpha star of Pisces) belongs to Gong Beixuan Wu and is also the main star of Pisces, about 25. 1 light-year away from the earth. Its apparent magnitude is 1. 16, which is a first-class star and the18th bright star on earth except the sun.

The spectral classification of Beiluoshimen is A3V, which is about 1.84 times the diameter of the sun, 1.9 times the mass and 15 times the brightness. It is only about 200 million to 300 million years old and is a very young star. As the main star of Pisces (Alpha Pisces), Beiluoshimen is also a bright star of 18, with an apparent magnitude of 1. 16, an absolute magnitude of 1.74 and a distance of 25. 1 light-year.

In the southern sky in autumn night, the only striking bright stars are probably Beiluo Shimen and Toast. Moreover, Beiluoshimen is a lone star, and there are no other bright stars around, so Beiluoshimen has become the southernmost bright star that can be seen in most areas of China on autumn nights. As one of the few bright stars in the southern sky in autumn night, Beiluo Normal School has naturally received great attention.

In ancient Persia, Shimen in Beiluo, Bisuwu, Antares and Xuanyuan XIV were called the four heavenly kings, mainly because they were close to the ecliptic and almost evenly distributed on the ecliptic.

Extended data:

Around the North Rushmore Gate, the distance from North Rushmore Gate 133 to 158 astronomical units is surrounded by a disk-shaped dust cloud. 1998, through observation and speculation, people think that planets are likely to be produced in dust clouds. From June 5438, 2006 to 10, Professor AliceC. Quillen of the University of Rochester predicted the existence of this planet.

There is a known planet in North Fukushima, Hokuroshima. In May 2008, astronomer Paul Callas of the University of California, Berkeley successfully located the planet from photos taken by the Hubble Space Telescope between 2006 and 2008. The image of this planet was released on June 5438+065438+1October 65438+March 2008, and it is also the only extrasolar planet discovered by optical means.
