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.
The sun and the atmosphere of the sun are divided into several zones and layers. The solar interior, from the inside out, is made up of the core, radiative zone and the convective zone. The.
The sun's magnetic field is typically only about twice as strong as Earth's magnetic field. However, it becomes highly concentrated in small.
Sunspots 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. The number of sunspots.
Just like most other stars, the sun is made up mostly of hydrogen, followed by helium. Nearly all the remaining matter consists of seven other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon. For every 1 million.
The core of the Sun extends from the center to about 20–25% of the solar radius.It has a density of up to 150 g/cm(about 150 times the density of water) and a temperature of close to 15.7 million(K).By contrast, the Sun's surface temperature is about 5800 K. Recent analysis ofmission data favors the idea that the core is rotating faster than the radiative zone outside it. From an average distance of 93 million miles (150 million kilometers), Earth is exactly one astronomical unit away from the Sun because one astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. This unit provides an easy way to quickly compare planets' distances from the Sun.

Many stars are much larger – but the Sun is far more massive than our home planet: it would take more than 330,000 Earths to match the mass of the Sun, and it would take 1.3 million Earths to fill the Sun''s volume. The Sun is about 93 million miles (150 million kilometers) from Earth.

4 · Heat from the Sun makes Earth warm enough to live on. Without light from the Sun, there would be no plants or animals—and, therefore, no food and we wouldn''t exist. Heat and light might be important for life on Earth, but the Sun sends other stuff, too. The Sun sends lots of other energy and small particles toward Earth.

The Sun has several regions. The interior regions include the core, the radiative zone, and the convection zone. Moving outward – the visible surface or photosphere is next, then the chromosphere, followed by the transition zone, and then the corona – the Sun''s expansive outer atmosphere.

The part of the Sun we see from Earth – the part we call the surface – is the photosphere. The Sun doesn''t actually have a solid surface because it''s a ball of plasma. Above the Sun''s surface are its thin chromosphere and the huge corona (crown). This is where we see features such as solar prominences, flares, and coronal mass ejections.
