What are the names of the three stars in Scorpio circled in the picture? Can you tell me about the positional relationship between Antares and Jinxing?

Location: Right ascension 16: 26.3, declination -26 degrees 19. ?

Alpha star of Scorpio. China, also known as fire in ancient times, belongs to the heart of the Eastern Black Dragon. It is used to determine the season. It is red, with a magnitude of 0.92 and a distance of about 424 light years. Its radius is 600 times that of the sun, reaching 4170,000 km. The surface temperature is 3000 degrees, the volume is more than 200 million times that of the sun, and the mass is only 25 times that of the sun. So the density is only 8.6 million times that of the sun.

The main star of Antares is actually a semi-regular variable star, with a brightness of 0.9 to 1.8 and a dimming period of 48 years. The surface temperature is 3600K, the radius is 600 times that of the sun, the surface area is 360 thousand times that of the sun, but the mass is only 25 times that of the sun.

AntAres, the English name of AntAres, is a combination of Anti and ares. Ares is the name of God of War and Mars in Greek mythology, which means "the enemy of Mars". Because the brightness and color of Antares are very similar to those of Mars, and the orbits of both stars are on the ecliptic, when Mars runs to Scorpio, two red stars shine in the sky, so Antares is named. In ancient Persia, Antares, Bi Suwu, Xuanyuan XIV and Beiluoshimen were collectively called the four heavenly kings.

"Fire in July" means that Mars is heading west and the weather is cold. Modern astronomy is called "Alpha Star of Scorpio". This is a red Supergiant star. Antares and the other eye

What is the apparent magnitude? 5. What is the MK classification about? B4V's blue dwarf star forms a visual binary star with an orbital period of thousands of years. The blue companion star of Antares is a radio star, which was discovered in 1970s. The radio of blue companion antares and the radio of red Supergiant star antares and their brightness are all measured by very large antenna arrays. It is also found that the radio source near the blue companion star is actually located between the two satellites, which may be formed by the wind interaction between the two stars.

Legend has it that when China was in Zhuan Xu more than 4,000 years ago, he set up an official post of Huozheng, who was responsible for observing this star.
