Sun The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth. It is a nearly perfect spherical ball of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process.n the Sun's outer layer, from its surface to approximately 200,000 km below (70% of the solar radius from the center), the temperature is lower than in the radiative zone and heavier atoms are not fully ionized. As a result, radiative heat transport is less effective.

What is the Sun made of? The Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.

- Best Answer: The sun has a visible disk called the photosphere, which is always present. The outer portions of that disk appear slightly darker than the middle of the disk. That is known as limb darkening and it is also always present.

Temperature of the Sun The Sun has a temperature ranging from 6,000° Celsius at its surface which is hot enough to turn gold, tungsten and every metal on Earth into gas. It is around 15,000,000° Celsius in its center-far hotter than anything we can generate on Earth.

Sun The Sun is a G-type main-sequence star (G2V) based on spectral class and it is informally referred to as a yellow dwarf. It formed approximately 4.567 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud.he Sun has a magnetic field that varies across the surface of the Sun. Its polar field is 1–2 gauss (0.0001–0.0002 T), whereas the field is typically 3,000 gauss (0.3 T) in features on the Sun called sunspots and 10–100 gauss (0.001–0.01 T) in solar prominences.

Stars and Planets Our Sun is a star. It’s a vast ball made up of 74% hydrogen and 24% helium, with trace amounts of other elements. It has so much mass that the temperatures and pressures at its core are hot enough to ignite fusion. At the core of the Sun (and other stars), atoms of hydrogen are being fused into atoms of helium.

What Is the Sun Made Of? The temperature of the sun in this layer is about 27 million degrees Fahrenheit (15 million degrees Celsius). Hydrogen atoms are compressed and fuse together, creating helium. This process is called nuclear fusion. As the gases heat up, atoms break apart into charged particles, turning the gas into plasma.

General Astronomy/Print version The sun is made of Ionized gases mostly Hydrogen and about 25% helium. Light comes from the thermonuclear fusion that is achieved at the high temperatures in the core of the s … tar, at about 18 million degrees kelvin.he Sun is made of plasma, almost entirely hydrogen and helium. Plasma is superheated matter that is so hot that the elements have lost some or all of their electrons, it is beyond a gaseous state.

- Every day, the sun radiates (sends out) an enormous amount of energy—called solar energy. It radiates more energy in one day than the world uses in one year. This energy comes from within the sun itself. Like most stars, the sun is a big gas ball made up mostly of hydrogen and helium gas.

- The Sun belongs to a galaxy called the Milky Way. Astronomers estimate there are about 100 thousand million stars in the Milky Way alone. Outside that, there are millions upon millions of other galaxies also!

- The Sun is in the center of the solar system. Our solar system is always in motion. Eight known planets and their moons, along with comets, asteroids, and other space objects orbit the Sun. The Sun is the biggest object in our solar system.

- The sun is a big ball of gas and plasma. Most of the gas — 91 percent — is hydrogen. It is converted into energy in the sun's core. The energy moves outward through the interior layers, into the sun's atmosphere, and is released into the solar system as heat and light.

Earthâs Sun: Facts About the Sunâs Age, Size and History The sun was born about 4.6 billion years ago. Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula. As the nebula collapsed because of its gravity, it spun faster and flattened into a disk. Most of the material was pulled toward the center to form the sun.

Sun 1 The Earth is one of nine planets that orbit round the Sun in what we call the Solar System. 2  Solar is the adjective from Sun and comes from the Latin word for Sun – sol, which also gives us the French soleil. ( 3 and the word for Sun in several mother European languages).

Earthâs Sun: Facts About the Sunâs Age, Size and History The photosphere is the lowest layer of the sun's atmosphere, and emits the light we see. It is about 300 miles (500 km) thick, although most of the light comes from its lowest third. Temperatures in the photosphere range from 11,000 F (6,125 C) at bottom to 7,460 F (4,125 C) at top.unspots are relatively cool, dark features on the sun's surface that are often roughly circular. They emerge where dense bundles of magnetic field lines from the sun's interior break through the surface. [ Related: Largest Sunspot in 24 Years Wows Scientists, But Also Mystifies ].

- answer by stonek confidence votes 62 the sun is a star when we see the sun never look directly at the sun what we see is light coming from the sun itself when we see a planet or a moon look at planets they are fascinating what we see is the sun s light reflected off the surface of the planet moonhe sun is a star which is why it glows and gives off light and heat stars convert hydrogen into helium and other elements in a process called nuclear fusion the objects wh ich orbit a star are called planets

How Hot Is the Sun? The sun is a huge sphere of glowing gases that produce energy and light, which make life on Earth possible. The temperature of the sun varies tremendously, and not in ways you might realize. Hinode spacecraft captured this picture of our sun's chromosphere on Jan. 12, 2007.

Solar Energy The sun is a huge ball of gas, mostly hydrogen with a little helium. The gravitational attraction of all that mass makes enormous pressure in the interior that forces the hydrogen atoms to fuse together in a nuclear reaction that creates helium atoms and radiant energy.

Sun The Sun is a G-type main-sequence star that comprises about 99.86% of the mass of the Solar System. The Sun has an absolute magnitude of +4.83, estimated to be brighter than about 85% of the stars in the Milky Way, most of which are red dwarfs. The Sun is a Population I, or heavy-element-rich, star.n the Sun's outer layer, from its surface to approximately 200,000 km below (70% of the solar radius from the center), the temperature is lower than in the radiative zone and heavier atoms are not fully ionized. As a result, radiative heat transport is less effective.
