Sun is the star at the centre of our solar system. The sun can be defined as the solar system’s gravitational center. The gravitational pull of the solar system keeps the planets moving in place in the solar orbit. The sun is known to make an enormous gravitational pull that needs to be countered. More often than not, interplanetary space missions are known to travel in a circular fashion around the sun and they then spiral outward due to gravity.
Importance of the Sun in our life
Sun provides the vital energy for all life to grow. Plants and animals need sunlight for growth. Plants require sunlight for photosynthesis whereas animals including humans need sunlight to generate vitamin D for the skeletal system and psychological health. Geographical regions where there is insufficient sunlight or some religious cultures where there is minimal exposure to the skin have a high incidence of skin related diseases or even psychological and emotional illnesses.
In recent years, solar energy is gaining popularity as an alternative energy source. E.g., in Germany, the entire town of Wildpoldsried [also called the Solar City] is being powered by solar energy. Development of Solar Energy as an alternative energy source is vital for long-term sustainable growth.
In many cultures, Sun was worshipped as a God or the ultimate power symbol, e.g., most of the ancient cultures such as Egyptian, Hinduism, Greek, Chinese, African and Aztec. Many modern societies also have Sun temples, and they believe in Sun worship. Sun is worshipped in the form of a deity.
Sun and the Interplanetary Space Missions
The sun is an essential planetary body and provides the earth with a lot of functions. Let’s check them out!
- The sun can sometimes be termed as “unpredictable.” It is capable of sending intense solar flares up at times that are full of radioactivity and can damage spacecraft.
- The sun is also responsible for emitting a solar wind. This solar wind offers a slight but very noticeable push on spacecraft that are present in the solar system.
- The sun’s primary function is providing electromagnetic radiation that offers a lot of energy. Many space missions have been known to use this energy to make electricity through solar panels.
Evidently, the sun is an integral part of the earth and performs a wide range of functions that are essential to life on earth. It is an important symbol of life and vitality.
