Photosphere is the name given to the surface of the sun. The temperature at the core of the sun is 15.7 million K, a lot hotter than the photosphere\’s 5,778 K. This energy is produced via a nuclear reaction called nuclear fusion. During this process, two hydrogen nuclei bond to make one helium nucleus. This process involves release of energy.

A distance of 149.6 million kilometers separates the sun and the earth. The sun has a diameter of 1.392 million kilometers and an equatorial circumference of 4.379 million kilometers. These values are 109 times higher than the corresponding earth\’s measurements. Its surface area is 11,990 times that of earth, measuring 6.0877 trillion kilometer squared. Its volume is 1.3 trillion times that of earth.[I:http://cosmoread.com/wp-content/uploads/HaywoodHunter1.jpg]

Energy from the sun, known as solar energy, reaches the earth via radiation. The sun can only absorb a small fraction of solar energy; hence plenty of the radiated energy is reverberated back to space. Life on earth is dependent of the absorbed energy. More of its effects include tides, weather patterns and the earth\’s water cycle.

Plants use solar energy to make their own food, through a process called photosynthesis. This is the basic process that makes food available to all other living things. The sun is also responsible for the energy stored in fossils, as well as petroleum and coal.

Providing unlimited light and heat, the sun is the main source of energy to the earth. Extra applications of solar energy include lighting, generating electricity and in enhancing growth of plants in green houses. Considering all these factors, it is true to say that there can be no life on earth without the sun.
