SUN
- Star at the Center: The Sun is a star located at the center of our solar system. It is an enormous, nearly spherical ball of hot plasma that generates energy through nuclear fusion.
Source of Light and Heat: The Sun radiates immense amounts of light and heat, which provide energy for life on Earth and drive weather patterns, ocean currents, and the climate system.
Composition and Size: The Sun is primarily composed of hydrogen (about 74% of its mass) and helium (about 24%). It has a diameter of about 1.4 million kilometers (870,000 miles), making it approximately 109 times the diameter of Earth.
