First, the Sun is Yellow Dwarf Although the true color of the Sun is white, the Sun is classified as a type G yellow dwarf star (G2V). The classification does not only contain yellow stars, but can vary in color. Ranging from yellow to low-temperature stars, to white for hotter ones. The sun is classified as a yellow dwarf when it is white because of its temperature and luminosity. The temperature and luminosity of the Sun tend to be similar to yellow dwarf stars. So, to make it easier, astronomers classify the Sun in the same group a.
Second, the Sun is the Biggest in the Solar System The sun is the hottest, largest, most massive object in the solar system. Just imagine, more than 99.8% of the mass of the solar system is dominated by the Sun. In comparison, the diameter of the Earth is "only" around 12,742 kilometers, while the Sun has a diameter of about 1,392,600 kilometers. The weight of the Sun is also known to be around 333,000 times heavier than Earth. And don't ask about the volume, because the volume of the Sun is known to be more than 1.142 trillion cubic kilometers, which means it can hold about 1.3 million Earths in it. Third, the Sun Is Almost Perfectly Rounded Given the extraordinary size and volume of the Sun, the Sun is also is a celestial object that is almost perfectly round. The equator's diameter, which reaches almost 1.4 million kilometers, only differs about 10 kilometers with its polar diameter. This fact makes the Sun shaped like a ball that is almost perfectly round. If the Sun is shrinking — somehow to the size of a beach ball, the difference between the widest and narrowest diameter will be less than the width of a human hair.
Third, the Sun Throws the Wind The Sun does not like the wind on Earth. In astronomers' observations, it was known that the Sun produced about 386 billion billion mega Watts of energy through nuclear fusion, which converts hydrogen to helium This energy moves out of its core, and is continuously absorbed and re-emitted at the level and temperature of energy which gets lower until it appears, where some of it will seen as optical light. Some of the Sun's energy is then radiated as heat. The rest, the energy is released in the flow of energetic particles known as the solar wind, the wind that blows throughout the solar system at a speed of 450 kilometers per second. The wind is not without impact to Earth. Because it blows throughout the solar system, satellites that orbit the Earth are often affected. Sometimes too causing chaos in receiving radio and TV signals on Earth. Solar wind is also one of the causes of aurora.
Fourth, the Sun's Magnetic Field 3,000 times the Earth Although the Sun's magnetic field is only about twice as strong as the Earth's magnetic field, the differential rotation of the Sun which concentrates the field at several points in the Sun's body has made it 3,000 times stronger than the Earth's magnetic field. The magnetic concentration manifests as "Sun Spots" black spots that can appear on the surface of the Sun from latitude 45 degrees north to 45 degrees south of the equator of the Sun. Not only the Sunspots, a larger disturbance in the Sun's magnetic field can cause the appearance of flares or solar flares that can extend hundreds of thousands of kilometers above the surface of the Sun.
Fifth, the farther away from the sun, the hotter logically, the farther we are from the heat source, the cooler the ambient temperature we feel it should be. But, the fact is that the opposite happens to the Sun, you know! The farther we are from the Sun, the more heat. This was first known in 1939. The temperature in the core of the Sun is estimated at around 10 million degrees Celsius, but the surface temperature is "only" 5,500 degrees Celsius only A recent analysis of the SOHO spacecraft mission data shows that the very large temperature differences are due to a faster rotation rate in the core rather than throughout the radiative zone (surface).
