Like the earth, the sun spins on its axis and also moves through space. These are called solar prominences. The sunspots only look dark because the rest of the Sun is very bright. The temperature at the surface of the sun is about 6000°C while the temperature at its centre is about 20 million degrees Celsius. The diameter of the sun is about 14 x 105 kilometres. The chromosphere is the first layer of the Sun which can be seen, especially during a solar eclipse when the moon is covering most of the Sun and blocking the brightest light. The Sun and everything that orbits it is in the Milky Way. Once this got big enough, the huge pressure inside started a fusion reaction. 1.3 million Earths can fit inside the Sun.[16]. At the center of that huge cloud, gravity caused the material to build up into a ball. The Sanctum Sanctorum is called the main Temple. It also gives off a stream of particles, which reaches Earth as "solar wind". The age of the sun is about 46×10 ⁿ years . 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. Compared with the millions of other stars, the sun is a medium sized star and of average brightness. Thus, the star nearest to the earth is the sun. The Sun comprises about 99.86% of the mass of the Solar System. [15] It has existed for a little over 4.5 billion years. The Questions and Answers of Write a short note on the two planets nearest to the sun? On the other hand, the earth takes 365 days and 6 hours to revolve around the sun. (2015). [23][24], The Sun's chemical composition was gotten from the interstellar medium. Some space telescopes, including the ones that orbit the Sun have seen huge arches of the Sun's matter extend suddenly from the Sun. The Sun temple at Modhera in Gujarat is dedicated to the Sun god. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, dust and gas. Distant future of the Sun and Earth revisited. "IAU 2015 Resolution B3 on Recommended Nominal Conversion Constants for Selected Solar and Planetary Properties". Each time an atom of helium is formed, tremendous amount of energy is released in the form of heat and light. The energy this released caused that ball to heat and shine. These molecules can be seen on the Sun with special instruments called spectroscopes.[27]. Heating of the solar and stellar coronae: a review. The Sun is a G-type main-sequence star. In the centre of the sun, hydrogen atoms are continuously combining to produce atoms of helium. [26], The minimum temperature zone, the coolest layer of the Sun, is about 500 kilometres (310 miles) above the photosphere. Sunspots, prominences and flares become rare, and then numerous, and then rare again, every 11 years. The hydrogen and most of the helium in the Sun would have been produced by Big Bang nucleosynthesis in the first 20 minutes of the universe. When the sun rises it becomes day and when it sets it becomes night. In the long term, the Earth's future depends on the Sun, and the Sun is going to be fairly stable for the next 5 billion years. The Sun is about a hundred times as wide as the Earth. The light that the Earth receives from the Sun is radiated from this layer. Please note that sun is the only star having a known system of planets with life on one of its planets, called earth. 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. Solar prominences come in many different shapes and sizes. This page was last changed on 22 October 2020, at 12:28. The Sun is about a hundred times as wide as the Earth. It can take between 10,000 and 170,000 years for the energy in the core of the Sun to escape. The transition is between two very different layers. Schröder K.-P. & Smith R.C. The source of all this energy is nuclear fusion. The lotuses open with the sunshine and close itself with the sunset. Every day morning I look at the sun through my window. [30] We do not understand why the corona is so hot. The Sun is the star in the center of our solar system. The planets and other objects in the sky reflect a part of the sunlight falling on them due to which they become visible to us. The sun appears to be larger and brighter because it is much more nearer to the earth than any other star. The sun is a big ball of fire. In the hottest regions it is 8,000,000–20,000,000 K (14,400,000–36,000,000 °F). It consists mostly of hydrogen gas. The corona continuously expands into space forming the solar wind, which fills all the Solar System. The Sun is a type of star called a G-type main-sequence star based on its spectral class. [28] It can be seen from space using telescopes that can sense ultraviolet light. [23][24], Five layers make up the atmosphere of the Sun. It is a yellow dwarf star. The Sun orbits around the centre of the Milky Way. In a way, we can say that sun is the head of solar family or solar system. The surface temperature of sun is 5500 degree Celsius . Then, over several hundred billion or even a trillion years, the Sun would fade into a black dwarf. It is estimated to be brighter than about 85% of the stars in the Milky Way galaxy. ADVERTISEMENTS: Here is your essay on Solar System! Content Guidelines 2. The heavier elements were produced by stars that died before the Sun was formed. The Solar System is made up of all the planets that orbit our Sun. The sun rises in the East and sets in the West. 2008. Mamajek, E.E. The weight of the sun is 2×10 ³ⁿ kg . The sun rises early in the morning even before I get up. Here you can publish your research papers, essays, letters, stories, poetries, biographies and allied information with a single vision to liberate knowledge. Below this layer, the Sun is opaque, or not transparent to light. It gives off energy as light. Short Essay on Sun. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. Privacy Policy3. At that speed, it still takes 230 million years for a full orbit. If there is no sun it will be dark everywhere. Some of them are so large that the Earth could fit inside of them, and a few are shaped like hands. Nuclear fusion is the reaction in the star which turns hydrogen into helium and makes huge amounts of energy. Compared with the millions of other stars, the sun is a medium sized star and of average brightness. The Sun is a star like many others in our Milky Way galaxy.

These areas are caused by the Sun's magnetic field. That includes light, infra-red energy (heat), ultraviolet light and radio waves. Copyright © 2015 PublishYourArticles.Net, All rights reserved. The Sun is a type of star called a G-type main-sequence star based on its spectral class. ; Prsa, A.; Torres, G.; et, al. The sun has nine major planets revolving round it. It has a temperature of about 4,100 K (3,830 °C; 6,920 °F). In the bottom part it touches the photosphere and gravity shapes the features. The Sun is mainly composed of hydrogen and helium. Even our earth reflects a part of the sunlight falling on it. [25] It is believed that Alfvén waves may pass through to heat the corona. It has existed for a little over 4.5 billion years. In a billion years or so, increased solar energy will boil away the Earth's atmosphere and oceans. Since the Sun is all gas, surface features come and go. [21], Scientists think that the Sun started from a very large cloud of dust and small bits of ice about 4.567 billion years ago.[22]. The heliosphere is the thin outer atmosphere of the Sun, filled with the solar wind plasma. The last total solar eclipse occurred on Dec. 26, 2019, and was visible from Saudi Arabia, India, Sumatra and Borneo, with a partial eclipse visible in Australia and much of Asia. [35] The Sun will expand beyond orbits of Mercury, Venus, and probably Earth. The Sun moves at 820,000 km an hour. Revolution period in the milky way is 225 million years. If the Sun is viewed through a special solar telescope, dark areas called sunspots can be seen. [19], The Sun is the brightest object in the Earth's sky. After the Sun reaches a point where it can no longer get bigger, it will lose its layers and form a planetary nebula. [20] It takes 8 minutes and 19 seconds for light to travel from the Sun's horizon to Earth's horizon. It is considered to be the Sun’s flower. Life on Earth depends on light and heat from the sun. The earth takes 24 hours to rotate on its axis, causing us to experience the day and the night. The Sun has an absolute magnitude of +4.83. Partial eclipses slightly outnumber total eclipses by 7 to 6.[32]. It is the star round which the earth and other planets revolve. The Sun would be up to 250 times its current size, as big as 1.4 AU (210,000,000 kilometres; 130,000,000 miles) and will swallow up the Earth. is done on EduRev Study Group by Class 6 Students. It is a hot ball of gases that gives off great amounts of energy . Rotational period of sun is 25 days . Earth's fate is still a bit of a mystery. Earth: We all live on planet earth. At the top, the transition layer touches the corona. 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. [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 is not a solid body. The solar transition region is the part of the Sun's atmosphere, between the chromosphere and outer part called the corona. Erdèlyi R. & Ballai I. Related: Chapter Notes - The Earth in the Solar System? It has a mass of 1.9891 × 10 30 kg. [29][30] It can be seen during a solar eclipse or with an instrument called a coronagraph. It is this energy which makes the sun shine. It is going to continue for at least as long. In any event, the ocean and air would have vanished before the Sun gets to that stage. Astrophysicists say our Sun is a G-type main-sequence star in the middle of its life. The planets travel with the sun through millions of stars in our galaxy at a speed of about 70,000 kilometres per hour. The chromosphere, transition region, and corona are much hotter than the outer photosphere surface of the Sun. The heavier elements were released into the interstellar medium when the star exploded as a supernovae. The corona is the outer atmosphere of the Sun and is much bigger than the rest of the Sun. The sun is the star at the center of the solar system . The sun is a star.
