Sun Facts…
The Sun's energy output is produced by nuclear fusion reactions.
Nuclear Fusion-a nuclear process whereby several small nuclei are combined to make a larger one whose mass is slightly smaller than the sum of the small ones.

Sun Facts…
The surface of the Sun is called the photosphere. It is at a temperature of about 5800 K.
A small region known as the chromosphere lies above the photosphere.

Sun Facts…
Sunspots are "cool" regions, only 3800 K (they look dark only by comparison with the surrounding regions). Sunspots can be very large, as much as 50,000 km in diameter.

Sun Facts…
In addition to heat and light, the Sun also emits a low density stream of charged particles (mostly electrons and protons) known as the solar wind which propagates throughout the solar system at about 450 km/sec.

Sun Facts…
The solar wind has large effects on the tails of comets and even has measurable effects on the trajectories of spacecraft.
