sun

in #esteem6 years ago (edited)
When we see the sun from the direction of the earth we certainly think the sun is very beautiful, but we know what the sun is? The sun is a very large incandescent bulb that is the center of the solar system. The size of the sun is 100 times greater than the size of the earth which has a diameter of about 1.4 million km and weighs about 300 thousand times the weight of the earth which has a temperature of about 6,000 ° C from the surface of the sun. . The sun is formed from a collection of hydrogen and helium gas. The sun consists of several parts arranged in layers like the sun's core, photosphere, chromosphere, corona.

According to the science of the sun has a gravitational pull 28 times stronger than the gravitational pull of the earth. This means someone who weighs 90 kg on the surface of the earth, if it is on the surface of the sun, weighs 28 × 90 kg or equal to 2,520 kg or 2 1/2 metric tons. That is the excessive force of gravity.

Scientists say that, the surface (skin) of the sun is called the photosphere. From here comes the sunlight that we can see on earth. The temperature of this layer is 6,000 ° Kelvin. The surface of the photosphere is not a flat, but mottled (granulating) plane, called granulation of the photosphere. On the surface of the photosphere looks black places, called sun spots (sun spots). The appearance of these stains can cause electrical disturbances in the Earth's atmosphere, resulting in disruption in radio broadcasts and magnetic needles or we often hear signal interference.

Whatever the explanation of the sun for us lay people desperately need the sun, the sun is very beneficial to all beings, other than that the inhabitants of the earth rate that the sun is very unique and very beautiful when seen at certain times, so there is to say that it is the light.
