What does the red giant antares look like?

On a sunny night in summer, we sat in the yard to enjoy the cool. Looking up at the sky, you can see that there is a big constellation in the south section of Yinhe River-Scorpio. Scorpio is a big scorpion pattern composed of many bright stars. The brightest star in Scorpio is called Alpha, and in China it is called Antares.

Every early spring evening, on the eastern horizon, only Antares tells us that spring is coming with bright red light. It was by observing Antares that the ancients in China decided the season of spring ploughing. In fact, the brightness of Antares ranks 16 in the stellar world, which is not outstanding. However, the brightness in the infrared region is brighter than Sirius, which is the brightest in the whole day. Antares is a huge red star. Its diameter is 900 million kilometers. If we travel around the world by jet fighter, it will take 150 years or more. The diameter of the sun is 109 times that of the earth, and its volume is1300,000 times that of the earth. However, compared with antares, the sun is simply a baby. The diameter of Antares is about 640 times that of the sun, and its volume is enough to accommodate 260 million suns. Antares is a well-deserved "super red giant".
