The sun is a star being in a solar arrangement. The sun is revolving. Are needed eight minutes so that the sun's rays reach the earth. In the center of the sun even fifteen milionów degrees Celsius can be. In a second the sun is losing four milion ton of its mass. The sun ranks among the group of yellow short men.

Earth is our planet.
 Mars - the fourth according to the solar system planet from the Sun.

The sun is the star at the center of the solar system. It is a hot ball of gases that gives off great amounts of energy. Life on Earth depends on light and heat from the sun.

Solar storms can damage communication devices on Earth that rely on satellites in space.

Sunspots are areas on the sun that appear darker because they're cooler than the rest of the sun. Sunspots are not permanent and they can move slowly across the surface of Sun changing size as they move. Sunspots were observed as far back as 364 BC by astronomers in Ancient China.

Solar Flares

2018-03-01 12:23:57 UTC

Solar flares happen when magnetic energy builds up in the sun’s atmosphere and has to be released. The release is sudden and explosive, and the radiation reaches Earth in about eight minutes. Not all solar flares emit the same amount of energy. C-class flares are the weakest, M-class sun storms are in the middle, and X-class flares are the strongest.

The Sun is so large that the Earth could easily fit inside the Sun a million times.

The Sun was born in a vast cloud of gas and dust around 5 billion years ago. Indeed, these vast nebulae are the birth places of all stars. Over a period of many millions of years, this gas and dust began to fall into a common center under the force of its own gravity.

Słońce

The sun is about 5 billion years old. Its surface temperature reaches 5500 ° C, but inside it reaches 14 million ° C. In the solar nucleus, hydrogen transforms into helium, the process releases enormous energy. On the surface of the Sun you can observe spots, flares and huge remorses of matter - protuberances.

In a total solar eclipse it is often possible to see chromosphere, the layer of thin gas between the Sun’s surface and the Sun’s corona. You may be able to see the chromosphere as a thin red line in Figure 3 with the corona outside it.

Figure 3. The moon has eclipsed the Sun which cannot be seen. Only the chromosphere and corona of the Sun can be seen.

Sometimes darker spots are seen on the surface of the Sun. These are magnetic areas which are cooler than the rest of the Sun. They are called Sunspots.
The great Polish scientist Nicholas Copernicus (1473-1543) published a book at the end of his life, in 1543, in which he tried to prove that the planets orbited round the Sun; the book’s title was De Revolutionibus Orbium Coelestium (Concerning the revolution of the heavenly spheres).

This spectacular picture of the half-blocked sun was captured on March 29 when the orbiting Solar Dynamics Observatory was hidden behind the Earth.

SDO shoots dazzling photos and videos from the sun 22,000 miles above the Earth's surface. Twice a year the spacecraft enters the eclipse period when the Earth blocks its view for a maximum of 72 minutes a day.

In contrast to the sharp shadow observed during the lunar eclipse, the shadow of the Earth has an uneven edge due to the changing atmosphere. Places where the atmosphere is thicker, block more sunlight than places where it is thinner. Brighter spots in the sun can also penetrate into the atmosphere, sending beautiful shadows through Earth's shadow.

-The Sun gives life to the Earth and the Earth would have no life at all without the energy it receives from the Sun.
-The Sun is only one of millions and millions of stars in the Galaxy.
-The Sun is 92.96 million miles or 149.6 million kilometres from the Earth.
-It takes about 8 minutes for the sunlight to be seen on the earth after it has left the Sun.
-The temperature of the Sun is around 10,000 degrees Fahrenheit. The inner core is much hotter. To put this in perspective, a day of 90 degree weather feels hot to us. Water boils at 212 degrees.

The sun is a gigantic sphere of gases (70% hydrogen of 30% helium). Thanks to the synthesis of these elements, energy is generated that is converted into heat, light and ultraviolet (harmful) radiation. The temperature of the sun is 19000000 degrees Celsius! The sun has come to the half of her life. Solar energy is needed for us to live, animal life and plants. The next planets of the Sun are: Mercury, Venus, Earth, Mars.

The Sun’s surface temperature is around 5500 degrees Celsius (9941 degrees Fahrenheit), so pack plenty of sunscreen if you plan on visiting (remembering that the average distance from the Sun to the Earth is around 150 million kilometers).
