What are the three suns in the sky? Who can explain?
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 1, 392,000 km, and its mass is about 2× 10 kg, accounting for 99.86% of the total mass of the solar system, of which about three quarters are hydrogen and the rest is almost helium.
In the vast universe, the sun is just a very ordinary star, and the solar wind under construction extends to the top of the heliosphere outside 100 astronomical units. The "bubble" formed by the solar wind is called the solar circle and is the largest continuous structure in the solar system. The sun or the sun is a star located in the center of the solar system, and it is almost an ideal sphere intertwined with hot plasma and magnetic field.
Its diameter is about 65,438+0,392,000 (65,438+0.392× 65,438+006) km, which is equivalent to 65,438+009 times the diameter of the earth, and its mass is about 2× 65,438+00 kg (330,000 times the mass of the earth
