The Sun is a massive, luminous, and hot star that is at the center of our solar system. It is a nearly perfect sphere of hot plasma, primarily composed of hydrogen and helium, undergoing nuclear fusion in its core. This fusion process is what produces the immense amount of energy and light that the Sun emits. Estimated features of the Sun are: Composition: The Sun is primarily composed of about 74% hydrogen and 24% helium. Other trace elements make up the remaining 2% of its mass. Energy Production: The Sun's core is extremely hot and under immense pressure, which enables nuclear fusion to occur. Hydrogen atoms in the core combine to form helium, releasing a tremendous amount of energy in the form of light and heat. This energy generation is what provides the heat and light for our solar system. Size: The Sun is incredibly large. It has a diameter of about 1.4 million kilometers (870,000 miles), which is approximately 109 times the diameter of Earth. It makes up about 99.86% of the
