You can't look at the Sun through a telescope, you can ruin your eyes or go blind altogether. Flame and raging energy, power and fury - these are the components of this star. But it gives people warmth and light, without which there would be no life on planet Earth.

Step 1

The sun is the largest star in our galaxy. This is despite the fact that the Sun bears the "title" of the Yellow Dwarf. The diameter of this star is 1,400,000 km, which is approximately 109 times the diameter of the Earth, and the diameter of the supergiant star Betelgeuse is 850 times the diameter of the Sun. However, even Betelgeuse is far from the largest star in the Universe. The distance between the Sun and the Earth is 150 million km or 93 million miles. Sunlight covers this huge gap in just eight minutes

Step 2

Despite its small size, the Sun has a surface temperature of 6,000 degrees Celsius or 10,800 degrees Fahrenheit, and at the very center of the star the temperature is approximately 15-18 million degrees Celsius. The sun is made of hydrogen and helium, but because of these high temperatures, these substances are in a state of plasma. This star produces 3,000,000.0000,000 megawatts of energy. Much of this immense strength and power is simply dissipated in space

Step 3

But some of it serves the Earth as a source of light and heat. Energy is thrown into space as a result of constant and powerful explosions on the surface of the Sun. As a result, radiation arises, which reaches us already in the form of electromagnetic waves. These explosions are due to thermonuclear fusion taking place inside the star's core, which is about 10 times denser than lead and is the ideal place for such fusion. Hydrogen atoms are compressed so much that helium is formed

Step 4

Due to the powerful collision of protons, the resulting energy is released in the form of an explosion and reaches the Earth in the form of photons. But at different times of the year and time of day, light and heat are unevenly distributed around the planet. When one side of the earth is facing the sun, it is daytime. The planet rotates on its axis, and the day is replaced by night, and night by day. The seasons change approximately according to the same principle, only in this case everything depends on the tilt of the Earth in relation to the Sun.
