[29] The average temperature of the corona and solar wind is about 1,000,000–2,000,000 K (1,800,000–3,600,000 °F). The Sun temple at Modhera in Gujarat is dedicated to the Sun god. At the top, the transition layer touches the corona. The Solar System is made up of all the planets that orbit our Sun. Temperature at the core is 14×10ⁿ degree Celsius . The energy radiated from the Sun pushed away the rest of the cloud from itself, and the planets formed from the rest of this cloud. It is the star round which the earth and other planets revolve. The equatorial diameter of sun is 1.5 million km . The Sun is about a hundred times as wide as the Earth. The Questions and Answers of Write a short note on the two planets nearest to the sun? The sun is a mass of hot gases, about 109 times bigger in size than the earth; 330,000 times as heavy as the earth and about 150 x 106 kilometres away from the earth. The Sun is about a hundred times as wide as the Earth. Image Source: noaanews.noaa.gov/stories2004/images/sun111004-1319z.jpg. It has a temperature of about 4,100 K (3,830 °C; 6,920 °F). Once this got big enough, the huge pressure inside started a fusion reaction. (2015). It has an apparent magnitude of −26.74. The transition is between two very different layers. It is estimated to be brighter than about 85% of the stars in the Milky Way galaxy. The Sun is a star like many others in our Milky Way galaxy. The heavier elements were produced by stars that died before the Sun was formed. If the Sun is viewed through a special solar telescope, dark areas called sunspots can be seen. Privacy Policy3. Life on Earth depends on light and heat from the sun. The source of all this energy is nuclear fusion. The energy this released caused that ball to heat and shine. [23][24], Five layers make up the atmosphere of the Sun. [33][34] Calculations suggest that the Earth might move to a wider orbit. Nuclear fusion is the reaction in the star which turns hydrogen into helium and makes huge amounts of energy. The corona continuously expands into space forming the solar wind, which fills all the Solar System. Before publishing your Articles on this site, please read the following pages: 1. It is going to continue for at least as long. Astrophysicists say our Sun is a G-type main-sequence star in the middle of its life. Every day morning I look at the sun through my window. [30] We do not understand why the corona is so hot. Compared with the millions of other stars, the sun is a medium sized star and of average brightness. It can take between 10,000 and 170,000 years for the energy in the core of the Sun to escape. It has existed for a little over 4.5 billion years. It gives off energy as light. The Sanctum Sanctorum is called the main Temple. The Sun fuses about 600 million tons of hydrogen into helium every second. The earth takes 24 hours to rotate on its axis, causing us to experience the day and the night. [20] It takes 8 minutes and 19 seconds for light to travel from the Sun's horizon to Earth's horizon. At the center of that huge cloud, gravity caused the material to build up into a ball. [29][30] It can be seen during a solar eclipse or with an instrument called a coronagraph. The Sun moves at 820,000 km an hour. (. [25] It is believed that Alfvén waves may pass through to heat the corona. [28] It can be seen from space using telescopes that can sense ultraviolet light. Eventually, the Sun will shrink into a white dwarf. Distant future of the Sun and Earth revisited. [15] It has existed for a little over 4.5 billion years. The light that the Earth receives from the Sun is radiated from this layer. Revolution period in the milky way is 225 million years. Compared with the millions of other stars, the sun is a medium sized star and of average brightness. It is this energy which makes the sun shine. It is a yellow dwarf star. In any event, the ocean and air would have vanished before the Sun gets to that stage. The Sun is a type of star called a G-type main-sequence star based on its spectral class. All these planets revolves around the sun and are part of our solar system. [25] This part of the Sun is cool enough to allow simple molecules such as carbon monoxide and water to form. Earth: We all live on planet earth. It is going to continue for at least as long. A lunar eclipse happens when the moon passes through the shadow of the Earth which can only occur during a full moon.The number of lunar eclipses in a single year can range from 0 to 3. When the sun rises it becomes day and when it sets it becomes night. It should be noted that sun is the main source of heat and light energy for all the members of the solar system including the earth. Erdèlyi R. & Ballai I. The Sun is a G-type main-sequence star. [17][18] The Sun is a Population I star. These areas are caused by the Sun's magnetic field. Stars like the Sun become red giants at a later stage. Though sun is the nearest star to the earth, even then it is at a distance of 150 x 106 kilometres from the earth and light, travelling at a great speed of 300,000 kilometres per second, takes about 8 minutes to reach us from the sun. At that speed, it still takes 230 million years for a full orbit. However, in the very long term the Earth will probably be destroyed as the Sun increases in size. [19], The Sun is the brightest object in the Earth's sky. It has a mass of 1.9891×1030 kg. The sun has nine major planets revolving round it. The sun is the star at the center of the solar system . It is situated on the bank of the river Pushpavati. Some of them are so large that the Earth could fit inside of them, and a few are shaped like hands. 2007. In a few more billion years, they think the Sun will get bigger and become a red giant star. Mamajek, E.E. Earth's fate is still a bit of a mystery. After the Sun reaches a point where it can no longer get bigger, it will lose its layers and form a planetary nebula. The weight of the sun is 2×10 ³ⁿ kg . 2008. Schröder K.-P. & Smith R.C. The sun rises early in the morning even before I get up. The surface temperature of sun is 5500 degree Celsius . The sun can also be used as a source of solar energy. The solar transition region is the part of the Sun's atmosphere, between the chromosphere and outer part called the corona. Some space telescopes, including the ones that orbit the Sun have seen huge arches of the Sun's matter extend suddenly from the Sun. ; Prsa, A.; Torres, G.; et, al.
