有两个..1.The Sun is the most prominent feature in our solar system. It is the largest object and contains approximately 98% of the total solar system mass. One hundred and nine Earths would be required to fit across the Sun's disk, and its interior could hold over 1.3 million Earths. The Sun's outer visible layer is called the photosphere and has a temperature of 6,000°C (11,000°F). This layer has a mottled appearance due to the turbulent eruptions of energy at the surface. Solar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth's air pressure at sea level) is so intense that nuclear reactions take place. This reaction causes four protons or hydrogen nuclei to fuse together to form one alpha particle or helium nucleus. The alpha particle is about .7 percent less massive than the four protons. The difference in mass is expelled as energy and is carried to the surface of the Sun, through a process known as convection, where it is released as light and heat. Energy generated in the Sun's core takes a million years to reach its surface. Every second 700 million tons of hydrogen are converted into helium ashes. In the process 5 million tons of pure energy is released; therefore, as time goes on the Sun is becoming lighter. The chromosphere is above the photosphere. Solar energy passes through this region on its way out from the center of the Sun. Faculae and flares arise in the chromosphere. Faculae are bright luminous hydrogen clouds which form above regions where sunspots are about to form. Flares are bright filaments of hot gas emerging from sunspot regions. Sunspots are dark depressions on the photosphere with a typical temperature of 4,000°C (7,000°F). The corona is the outer part of the Sun's atmosphere. It is in this region that prominences appears. Prominences are immense clouds of glowing gas that erupt from the upper chromosphere. The outer region of the corona stretches far into space and consists of particles traveling slowly away from the Sun. The corona can only be seen during total solar eclipses. The Sun appears to have been active for 4.6 billion years and has enough fuel to go on for another five billion years or so. At the end of its life, the Sun will start to fuse helium into heavier elements and begin to swell up, ultimately growing so large that it will swallow the Earth. After a billion years as a red giant, it will suddenly collapse into a white dwarf -- the final end product of a star like ours. It may take a trillion years to cool off completely.2.The Solar System, is the stellar system comprising the Sun and the retinue of celestial objects gravitationally bound to it: the eight planets, their 162 known moons[1], three currently identified dwarf planets and their four known moons, and thousands of small bodies. This last category includes asteroids, meteoroids, comets, and interplanetary dust. The principal component of the Solar System is the Sun (astronomical symbol ); a main sequence G2 star that contains 99.86% of the system's known mass and dominates it gravitationally.[2] Because of its large mass, the Sun has an interior density high enough to sustain nuclear fusion, releasing enormous amounts of energy, most of which is radiated into space in the form of electromagnetic radiation, including visible light. The Sun's two largest orbiting bodies, Jupiter and Saturn, account for more than 90% of the system's remaining mass. (The currently hypothetical Oort cloud, should its existence be confirmed, would also hold a substantial percentage).[3] In broad terms, the charted regions of the Solar System consist of the Sun, four rocky bodies close to it called the terrestrial planets, an inner belt of rocky asteroids, four gas giant planets, and an outer belt of small, icy bodies known as the Kuiper belt. In order of their distances from the Sun, the planets are Mercury ( ), Venus ( ), Earth ( ), Mars ( ), Jupiter ( ), Saturn ( ), Uranus ( ), and Neptune ( ). All planets but two are in turn orbited by natural satellites (usually termed "moons" after Earth's Moon), and every planet past the asteroid belt is encircled by planetary rings of dust and other particles.

英文名称：

sun

体积是地球的130万倍，太阳系的中心天体。银河系的一颗普通恒星。与地球平均距离14960万千米，直径139万千米，平均密度1.409克/厘米3，质量1.989*10^33克，表面温度5770开，中心温度1500万开。由里向外分别为太阳核反应区、太阳对流层、太阳大气层。其中心区不停地进行热核反应，所产生的能量以辐射方式向宇宙空间发射。其中二十二亿分之一的能量辐射到地球，成为地球上光和热的主要来源。恒星也有自己的生命史，它们从诞生、成长到衰老，最终走向死亡。它们大小不同，色彩各异，演化的历程也不尽相同。恒星与生命的联系不仅表现在它提供了光和热。实际上构成行星和生命物质的重原子就是在某些恒星生命结束时发生的爆发过程中创造出来的。

太阳（Sun）是一颗普通的恒星，目前在赫-罗图上度过了主序生涯的一半左右。它是一个质量为1989.1亿亿亿吨（约为地球质量的33万倍）、直径139.2万km（约为地球直径的109倍）的热气体（严格说是等离子体）球。其平均密度为水的1.4倍，但这一平均密度隐含着很宽的密度范围，从超高密的核心到稀薄的外层。

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，他是一颗黄色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149597870km(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%的氦和少量重元素。太阳圆面在天空的角直径为32角分，与从地球所见的月球的角直径很接近，是一个奇妙的巧合（太阳直径约为月球的400倍而离我们的距离恰是地月距离的400倍），使日食看起来特别壮观。由于太阳比其他恒星离我们近得多，其视星等达到-26.8，成为地球上看到最明亮的天体。太阳每25.4天自转一周（平均周期；赤道比高纬度自转得快），每2亿年绕银河系中心公转一周。太阳因自转而呈轻微扁平状，与完美球形相差0.001%，相当于赤道半径与极半径相差6km（地球这一差值为21km，月球为9km，木星9000km，土星5500km）。差异虽然很小，但测量这一扁平性却很重要，因为任何稍大一点的扁平程度（哪怕是0.005%）将改变太阳引力对水星轨道的影响，而使根据水星近日点进动对广义相对论所做的检验成为不可信。

太阳基本物理参数

半径： 696295 千米.

质量： 1.989*10^30 千克

温度： 5800 ℃ （表面） 1560万℃ （核心）

总辐射功率： 3.83*10^26 焦耳/秒

平均密度： 1.409 克/立方厘米

日地平均距离： 1亿5千万 千米

年龄： 约50亿年

到达地球大气上界的太阳辐射能量称为天文太阳辐射量。在地球位于日地平均距离处时，地球大气上界垂直于太阳光线的单位面积在单位时间内所受到的太阳辐射的全谱总能量，称为太阳常数。太阳常数的常用单位为瓦/米2。因观测方法和技术不同，得到的太阳常数值不同。世界气象组织 （WMO）1981年公布的太阳常数值是1368瓦/米2。地球大气上界的太阳辐射光谱的99%以上在波长 0.15~4.0微米之间。大约50%的太阳辐射能量在可见光谱区（波长0.4~0.76微米），7%在紫外光谱区（波长<0.4微米），43%在红外光谱区（波长>0.76微米），最大能量在波长 0.475微米处。由于太阳辐射波长较地面和大气辐射波长（约3~120微米）小得多，所以通常又称太阳辐射为短波辐射，称地面和大气辐射为

长波辐射。太阳活动和日地距离的变化等会引起地球大气上界太阳辐射能量的变化。
