All About the Sun

Situated at the center of the solar system, the Sun is actually just a large star whose strong magnetic fields cause other solar matter, mainly planets, asteroids, comets, meteoroids and other debris, to orbit around it. The Sun is believed to be more than 4.6 billion years old, and is comprised of mostly hydrogen (74%) and helium (25%). The remaining 1% is made up of small amounts of various heavier elements.

Life on Earth as we know it would not be possible without the Sun. The solar energy from the Sun has supported and sustained terrestrial existence on Earth since the beginning of time. Plants utilize the Sun to aid in photosynthesis. Humans and other mammals require energy from the sun for visual light, heat, as well as for powering modern solar devices. The Sun is also directly responsible for determining and regulating the varying climates and weather cycles that occur on Earth.
