Bhaskar, often referred to as the Sun, is the star at the center of our solar system. It is a massive ball of hot plasma, primarily composed of hydrogen and helium. The Sun provides light and heat, making life possible on Earth. Its energy is produced through nuclear fusion, where hydrogen atoms combine to form helium, releasing vast amounts of energy. The Sun has a diameter of about 1.4 million kilometers and is approximately 93 million miles away from Earth. It plays a crucial role in regulating the climate and weather patterns on our planet. Additionally, the Sun's gravitational pull keeps the Earth and other planets in orbit around it.
