the sun's temperature.Is 5500 .

The sun is very hot and the sun core is around 13,600,000 degrees Celsius!.The sun is very hot because of the steam and the heat.The sun is hot because of the core that why earth has a core. The Sun is very steam because it can melt anything .

temperature.

The sun’s temperature is 5500.The temperature in the photo sphere is about 10,000 degrees F (5,500 degrees C). It is here that the sun's radiation is detected as sunlight. Sunspots on the photosphere are cooler and darker than the surrounding area. At the center of big sunspots the temperature can be as low as 7,300 degrees F (4,000 degrees C).

The chromosphere, the next layer of the sun's atmosphere is a bit cooler — about  7,800 degrees F (4,320 degrees C). Visible light from the chromosphere is usually too weak to be seen against the brighter photosphere, but during total solar eclipses, when the moon covers the photosphere, the chromosphere can be seen as a red rim around the sun.

Temperatures rise dramatically in the corona, which can also only be seen during an eclipse as plasma streams outward like points on a crown. The corona can get about 3.5 million degrees F (2 million degrees C). As the corona cools, losing heat and radiation, matter is blown off as the solar wind

The sun’s size

The sun is nearly a perfect sphere. Its equatorial diameter and its polar diameter differ by only 6.2 miles (10 km). The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km). You could line up 109 Earths across the face of the sun. The sun's circumference is about 2,713,406 miles (4,366,813 km).

• The Sun’s surface.Surface Area: 6,087,799,000,000 km2.

• The sun’s destiny.Density: 1.409 g/cm3

• The sun is one of more than 100 billion stars in the Milky Way. It orbits some 25,000 light-years from the galactic core, completing a revolution once every 250 million years or so. The sun is relatively young, part of a generation of stars known as Population I, which are relatively rich in elements heavier than helium. An older generation of stars is called Population II, and an earlier generation of Population III may have existed, although no members of this generation are known yet.

What is the sun made of.

Most of the gas — about 72 percent — is hydrogen. Nuclear fusion converts hydrogen into other elements. The sun is also composed of about 26 percent helium and trace amounts of other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon.These elements are created in the sun's core, which makes up 25 percent of the sun. Gravitational forces create tremendous pressure and temperatures in the core. The temperature of the sun in this layer is about 27 million degrees F (15 million degrees C). Hydrogen atoms are compressed and fuse together, creating helium and a lot of energy. This process is called nuclear fusion.The energy, mostly in the form of gamma-ray photons and neutrinos, is carried into the radiative zone. Photons can bounce around in this zone for about a million years before passing through the interface layer, or tachocline. Scientists think the sun's magnetic field is generated by a magnetic dynamo in this layer.The convection zone is the outermost layer of the sun's interior. It extends from about 125,000 miles (200,000 km) deep up to the visible surface or the sun's atmosphere. Temperatures cool in this zone, enough for heavier ions — such as carbon, nitrogen, oxygen, calcium and iron — to hold onto their electrons. This makes the material more opaque and traps heat, causing the plasma to boil or "convection."The convective motions carry heat quite rapidly to the surface, which is the bottom layer of the sun's atmosphere, or photosphere. This is the layer where the energy is released as sunlight. The light passes through the outer layers of the sun's atmosphere — the chromosphere and the corona — before reaching Earth eight minutes later.

Abundance of elements of the sun

Astronomers who have studied the composition of the sun have catalogued 67 chemical elements in the sun. There may be more, but in amounts too small for instruments to detect. Here is a table of the 10 most common elements in the sun.

Suns core.

The Sun’s core is a boiling hot. It is really hot core than Earth because the steam the  temperature.
