太阳内部温度都比外部温度高吗,请问太阳中心温度约多少°C?
最近有很多热心网友都十分关心太阳内部温度都比外部温度高吗,请问太阳中心温度约多少°C?这个问题。还有一部分人想了解太阳内部温度都比外部温度高吗。对此,和记百科小编「绾青丝」收集了相关的教程,希望能给你带来帮助。
太阳中心温度约14999726.85°C。核心是太阳内唯一能经由核聚变产生大量能量的区域,99%的能量产生在太阳半径的24%以内,而在30%半径处,核聚变反应几乎完全停止。其表面的温度大约在5500°C。
作为一颗恒星,太阳,其总体外观性质是,光度为383亿亿亿瓦,绝对星等为4.8。是一颗黄色G2型矮星,有效温度等于开氏5800度。太阳与在轨道上绕它公转的地球的平均距离为149597870千米(499.005光秒或1天文单位)。按质量计,它的物质构成是71%的氢、26%的氦和少量较重元素。它们都是通过核聚变来释放能量的,根据理论太阳最后核聚变反应产生的物质是铁和铜等金属。
太阳温度是指太阳的温度,分为表面,中心,日冕温度 其中 表面温度:约 5500 摄氏度 中心温度:约 2000万 摄氏度 日冕层温度:约 5乘以10的6次方 摄氏度。应该说是太阳大气外部温度比内部高.太阳内部指核心层、辐射层、对流层,太阳外部指光球层、色球层、日冕层,太阳外部通常指太阳大气,只有太阳大气是外部温度比内部高.
【英文介绍/For English】:
The central temperature of the sun is about 14999726.85°C. The core is the only region in the sun that can generate a lot of energy through nuclear fusion. 99% of the energy is generated within 24% of the suns radius, and at 30% of the radius, fusion reactions are almost completely stopped. The temperature of its surface is about 5500°C.
As a star, the sun, its overall appearance properties are 38.3 billion gigawatts of luminosity, and an absolute magnitude of 4.8. It is a yellow G2 dwarf with an effective temperature equal to 5800 degrees Kelvin. The average distance between the Sun and the Earth in orbit around it is 149,597,870 kilometers (499.005 light seconds or 1 AU). By mass, its material composition is 71% hydrogen, 26% helium and a small amount of heavier elements. They all release energy through nuclear fusion. According to the theory, the final fusion reaction in the sun produces metals such as iron and copper.
