The word "star" is interpreted as: stars Hé ngx and ng. (1) A glowing star. In the past, people thought that the positions of these stars were fixed, so they were named stars. In fact, any star is also moving, just because it is too far away from the earth, it is not easy to change its position. The part of speech is: noun. The phonetic notation is: ㄥㄒㄥ. The structure is: constant (left and right structure) star (upper and lower structure). The pinyin is: hé ngx and ng.
What is the specific explanation of the star? We will introduce you through the following aspects:
First, list and explain the details of this house viewing plan.
1. A celestial body that can glow by itself. It is named because it is difficult to detect the change of its position in a short time. According to brightness and luminosity, it can be divided into many grades. In ancient China, twenty-eight hotels were called "_ stars". Also refers to the common stars. Quote "Seven Years of the Spring and Autumn Period": "In summer and April, Xin Mao, the night _ stars are missing." Seven-year Biography of Gongyang Zhuanggong: "What is a _ star? Li Xing also. " Xu: "The sky exists forever, so it is called _ star. The words were listed in the sky at that time, so they were among the stars. " Shi Ming Tian Wenzhiyi: "Judging from today's experiment, the _ star has actually moved, which is not absurd."
Second, the national language dictionary
A star that glows and heats itself. The positions of constant stars are almost always the same, hence the name. It is estimated that there are hundreds of billions of stars in the Milky Way, and the sun is the closest star to the earth.
Third, the network interpretation
Stars (astronomical vocabulary) Stars are spherical luminous plasmas condensed by gravity, and the sun is the nearest star to the earth. Almost all the stars that can be seen at other nights on earth are in the Milky Way, but because of their long distance, these stars seem to be just fixed luminous points. Historically, those prominent stars have formed constellations and clusters, and the brightest stars have their own traditional names. The catalogue of stars compiled by astronomers provides many standards for the naming of different stars. At least during the life of a star, the star will undergo a nuclear fusion reaction in which hydrogen is fused into helium at the core, transfer energy from the inside of the star, travel a long distance, and then radiate from the surface to outer space. Once the hydrogen in the core is exhausted, the life of a star will be over. Some stars will undergo the process of stellar nucleus synthesis before the end of life; Some stars will undergo supernova nuclear synthesis before explosion, which will produce almost all natural elements heavier than helium. At the end of life, stars also contain degraded matter. Astronomers can learn about the mass, age, chemical element abundance and many other properties of stars by observing their motion, brightness and spectrum. The total mass of a star is the main factor that determines its evolution and ultimate fate: a star, including its diameter, temperature and other characteristics, will change at different stages of its life, and its surrounding environment will affect its rotation and movement. A chart depicting the temperature relative to the brightness of many stars, that is, the H-R chart, enables us to measure the age and evolution of stars.
