Active Sun,computer artwork. The Sun is a huge ball of hydrogen gas,ionised into a plasma by the immense temperatures that are generated by nuclear fusion at the core of the Sun. This fusion is ignited by the immense pressure generated by the Sun's mass. The activity of the Sun includes ejections of plasma from the surface of the Sun,and a surface in constant and violent turmoil. The Sun's light and heat directly or indirectly provides the energy for almost all of the life on Earth. The Sun's diameter is over 100 times the Earth's diameter. Its mass is more than that of 330,000 Earths. The Earth-Sun distance is an average of some 150 million kilometres | |
