Characteristics of Sun
As matter of fact, our solar system is composed of the Sun and all things which orbit around it in the nature of the Earth, the other eight planets, asteroids, and also comets. Even though the sun is a normal star but it is much closer to us compared to any other star. By studying the sun, we do notonly acquire about stars and galaxies but in the end, we can also learn more about the universe. Another significance of learning more about the sun is we will apprehend more that the Sun plays the role as big anchor which creates gravity that preserves our planet and the other planets of the solar system in a small space. It is clear that without sun, our planet which is the Earth would simply fly off loose into the universe.This …show more content…
According to Sharp, (2012), the Sun has a diameter of about 1,392,684 km (865,374 miles) which is 109 times the diameter of the Earth. Besides, the mass of the Sun is really hard to be put into the context and if it is written out with all the zeros it would be 1,988,920,000,000,000,000,000,000,000,000 kilograms (1.98892 x 1030 kilograms). Cain, (2012), states that, in terms of weight, the mass of the Sun is 333000 times the mass of the Earth and accounts for 99.8% of all the mass in the entire Solar System. However, as stated in this article written by Cain, the mass of Sun is actually slowly decreasing over time due to two processes involved. The first process is the fusion reactions in the core of the Sun which convert atoms of hydrogen into helium. Due to the fact that some of the Sun’s mass is lost through the fusion process, as atoms of hydrogen are converted into energy, the warmth we feel from the Sun is the Sun’s lost mass. The second way of Sun’s mass decreasing is due to the solar wind, which is constantly blowing protons and electrons into outer …show more content…
Choi, (2010), also claims that the sun and its atmosphere are divided into several zones and layers. The solar interior, from the inside out, is made up of the core which extends from the sun's centre to about a quarter of the way to its surface, radiative zone which extends from the core to 70 per cent of the way to the sun's surface, making up 32 per cent of the sun's volume and 48 percent of its mass andthe other one is convective zone which reaches up to the sun's surface, and makes up 66 per cent of the sun's volume but only a little more than 2 per cent of its mass. Choi also states in his article that, the solar atmosphere consists of the photosphere which is the lowest layer of the sun's atmosphere, and emits the light we see, chromosphere which is apparently made up entirely of spiky structures known as spicules, and at the top is called as a transition region and the super-hot corona, which are made of structures such as loops and streams of ionized gas. Beyond that is the solar wind, an outflow of gas produced from the
