What are the brightest stars in the spring night?
Arcturus is a first-class bright star, and its brightness is the fourth in the whole day. Because the second and third bright stars are too far away from the South Pole of the Earth, for most observers in China, after Sirius, the brightest star, disappeared, arcturus became the number one bright star in the sky. It is about 36 light years away from us, and its surface temperature is 4200 degrees Celsius, which is much lower than the surface temperature of the sun. It gives off orange light. However, its luminous ability is more than 100 times stronger than that of the sun. This is because the diameter of arcturus is 27 times that of the sun, and its luminous surface is more than 700 times that of the sun. Therefore, arcturus is a red superstar.
Of all the brightest stars that can be observed by naked eyes, arcturus runs the fastest. This behemoth has traveled in space for countless centuries at a speed of 483 kilometers per second. It is relatively close to our earth, and careful observation can show its movement on the celestial sphere.
In ancient China, arcturus was regarded as the one corner of the oriental black dragon (the other corner was Jiaosuyi), which is the origin of the word "Bighorn". Sumerians in Asia called the two river basins in arcturus "Muir? Sibana ",Arabs call arcturus" Harris? Asama means "faithful guardian of heaven". As the star that sets the direction and the main season, arcturus has always been concerned by people of all ages.
