About Sun
Our sun is a star, like millions of stars we see in the sky of our planet at night, but the star is very close to us, which is why we see a giant yellow circle provides us with light and heat necessary for our lives. Given the importance of the sun, and put NASA on its website
10 basic information about them
The sun is a star located within the gathering of millions of other stars, called "Milky Way." Surface is not solid at all, it is literally a big ball of gas, which is composed of 92.1% of hydrogen, and 7.8% of helium, and 0.1% other gases
What keeps these gases are grouped together? Why do not seep into the space? The sun is too heavy too, as the mass constituted 99.8% of the total mass of the solar system. This is a very heavy mass of the sun attract each other, it's stuck gases prevent them from stretching, and flees from the energy up to us on the ground, and we call it the sunshine
revolves around the sun eight planets, including the Earth, but these planets 166 satellites belonging to them. As a spin-five dwarf planets, at least around the sun, including the dwarf planet Pluto, as well as tens of thousands of asteroids, and about three billion comet ice body. Imagine that all these planets Bodies of not more than 0.2 mass% of the mass of the sun
to understand the magnitude of the sun, hoping your room where you read this article. Suppose that the door to this room is the sun, the earth will then serve as a small coin
in the heart of the sun heat up to about 15 million degrees Celsius. If the temperature reached the heart of the planet's fourth heat of the sun, this will lead to the entire planet exploded
center of the sun revolves around it. This is a component of the gases Center too, but severe intensity, meaning that the atoms of these gases are very adherent to each other and there are no spaces between them, making a very strong appeal
On the surface of the sun revolves around the center of gases at different speeds, if we assume that the sun flush placebo such as land line, the gas will be one cycle every 25 Earth days. The ends of "polar" sun revolves gases which every 36 days
Did you see Saturn? Have you noticed the outer rings that wrap around it? How old is believed that the sun has such episodes, but this is not true, the degree of the terrible heat has burned any particle approaching them
Sun's surface is the position you are in incandescent spots, storms and nuclear explosions that we see the sun. As for what we call the sun's corona Corona's name, and we see it in the event of a total eclipse, it extends to beyond the orbit of the dwarf planet Pluto
help us spacecraft sent by NASA to understand the nature of the sun, Fmrkph Genesis has collected many samples of solar wind before returning to earth as the images that have been obtained from the rovers SOHO and THEMIS helped us to study the sun characteristics and how they interact with the planet
. Remember this information, if you were not the great power of the sun exist, there would be no life on our planet
The diameter of the sun around 1392000 km average diameter of the Earth 12740 km. An area of 11 880 times more than the land area amounting to 510 million square kilometers. Size 1300000 times more than the size of the Earth's 1083 billion cubic kilometers. Heat combine 20 million degrees Celsius (up Earth's interior temperature to about 3,000 degrees Celsius). Away from the earth about 150 million km. Sun 1.4 g / cm 3 cubic density. Mass consisting of 73% hydrogen and 25% helium and 2% other elements. The temperature inside the central sun 15400 000 ° C, the temperature at the surface amounts to 6,000 degrees Celsius. Scientists calculate the age of the sun, reaching an estimated 1989 of about 4.50 billion years old
Chemistry sun
The sun is made up of several elements most important of hydrogen, which is equivalent accounted for three-quarters of the items in the sun, there is the equivalent of 23.8% of helium, and this percentage is increasing as a result of nuclear fusion of hydrogen reaching a proportion of 60%, and there are also oxygen and carbon, and iron, and neon, and other elements of a few percentages. By Type stellar classified sun as G2V, a dwarf yellow, indicating G2 symbol D on the surface temperature of the sun's heat and up to 5778 Kelvin, and indicates the symbol V that the sun is a star main sequence, the sun by astronomers small star tiny size and luster is higher than 85% the rest of the star galaxy Way where there are, most of the stars of the galaxy are red dwarfs, but equally absolute, a measure which neglected dimension measures the radiation of stars from the same distance 4.83 as much as the sun relative to the Earth of its stands at 26.74, and rays visible be nice yellow and green, Although the white color they appear from the yellow earth, and sat on Mars appear blue. The sun's corona extends into space continuously called the solar wind, a fact that a group of shipped out particles extending the heliopause and up to 100 astronomical units, contrary to what people think many people that the sun moves, they Solar System Center, Vtaathrk orbs affiliate around but they are all marching in vehicle movement in the spiral shape on the edge of one of the arms of the Milky way, and this is called the internal arm, Jabbar. There are several stars around the Earth nearly fifty-star classified the Sun ranked fourth, and these stars just seventeen light-years away, and the nearest star to Earth after the sun centaurs, and is just 4.2 light years away. Just round the sun from the Milky Way center between 24,000 to 26,000 light-years away, you need the sun to complement enacted by Hungarian (relative to the galaxy revolving around them) to about 225 to 250 million years ago. The average distance between the Sun and the Earth 149 600 000 kilometers, but this distance is fixed, the earth was moving in an elliptical path around the sun at the bifocal Tzmian apogee and perigee, there are always at the same distance from the sun
Symbolizes the sun in a circular motion within a point, which is the only star near the ground, a central solar system, revolves around several planets, asteroids and moons called all with the sun the solar system, the shape of almost spherical sun, and has a magnetic field, while the diameter amounts to approximately (1,392,684) kilometers, It is for the land equivalent of 109 times the diameter, with a sun block 2 × 1030 kilograms, which is also equivalent to (330,000) times the Earth's mass, and the mass of the sun equal to 99.86% of the total blocks of the solar system objects
