it's hot when the sun shines directly.
1. The sun
The sun is a star located in the center of the solar system, and it is almost an ideal sphere where hot plasma and magnetic field are intertwined. The diameter of the sun is about 1392(1.392×1? ) kilometers, equivalent to 19 times the diameter of the earth; The volume is about 1.3 million times that of the earth; Its mass is about 2×1? Kilogram (33 times that of the earth). From the chemical composition, about three-quarters of the mass of the sun is now hydrogen, and the rest is almost helium, including oxygen, carbon, neon, iron and other heavy elements with a mass of less than 2%. Nuclear fusion is used to release light and heat into space.
2. The distance between the sun and the earth
is about 15 million kilometers, which is too far, while the distance between the nearest and farthest sun and the earth is only 5 million kilometers, so the distance between the sun and us has little to do with the weather.
3. The age of the sun
The life of the sun is about 1 billion years. There are mainly protostars-main sequence stars-red giant stars-white dwarfs-black dwarf.
