What are some prominent features of the sun?
The sun, also known as Sol, is a gigantic ball of burning gas located in the center of the solar system, in case you have not noticed. The sun represents 99.8% of the solar system mass and continuously connects four million tons of overheated hydrogen into helium every second. Helium already accounts for 25% of their matter.
The sun is about halfway in its life cycle between its birth and the future transformation to a red giant star, with a diameter as wide as the Earth's orbit. After exhausting his nuclear fuel in about five billion years, most of his atmosphere escapes, creates a planetary nebula and leaves behind a small white dwarf. The white dwarf called the "stellar rest" is about half the weight of the sun, but with a volume comparable to the ground. Missing any nuclear fuel, slowly distracting its residual heat for many billions of years and eventually becomes a black dwarf. This life cycle is typical of low and medium -weight stars such as the sun.
the sun is almostPerfect balls and bulges the equator for only nine parts of a million. It is made of plasma, which is an overheated phase of the mass that consists of charged electrons soup with most hydrogen cores (protons) floating inside. The sun is convective and circulates its plasma between its layers. Plasma also rotates about once a month - 25 days on the equator, 35 days at the poles. The sun is the only body in the solar system made of plasma formed by a nuclear oven in the core.
The core of the sun is a place where all action occurs. The core extends about 0.2 solar radii from the epicenter of the sun and accounts for only 10% of the volume of the sun, but about 40% of its mass. It is about 15 times thicker than lead and it is the only part of the sun that creates its own heat through a nuclear fusion. It takes a huge amount of time for energy generated in the core -i to achieve the surface of the sun - estimates between 17,000 and 50 million years.
The distance from ground to sun is about eight and the third light minutes. It means that ifThe sun exploded, we wouldn't know about eight minutes. Hopefully it will never happen!
