The Sun
The Sun
• The Sun is our closest star. It is a
member of the Milky Way galaxy. The Sun
is a medium sized star. It is believed to be
over 4 billion years old.
• The center, or core, of the Sun is very hot.
A process called "nuclear fusion" takes
place there. Nuclear fusion produces a lot
of energy. This energy is called solar
energy.
Solar Energy
• Solar energy is the sun’s rays that are
radiated to earth. Radiate means to send
out in rays or waves.
• Solar energy can be converted into other
forms of energy on Earth, such as heat
and electricity.
The Sun
• The Sun is a huge, glowing ball at the
center of our solar system. It is a star
because it creates it’s own light.
• The sun provides light, heat, and other
energy to Earth that is needed for life to
exist.
• The sun is made up entirely of gas.
• Eight planets and their moons, tens of
thousands of asteroids, and trillions of
comets revolve around the sun.
Solar Flares
• The Sun also produces big explosions of
energy called solar flares. These flares
shoot fast moving particles off the Sun's
surface. These particles can hit the Earth's
atmosphere and cause a glow called an
aurora.

Sun Spots
• Sun spots are areas of the sun that appear
darker.
• At these spots there is intense magnetic
activity and causes the temperature to be
much lower.

The Sun helping Earth
• The sun is used by plants when they make
their own food in a process called
photosynthesis.
• Plants produce oxygen which all life needs
to live.
The Sun helping Earth
• The sun powers the water cycle. It’s
energy causes evaporation to occur.
The sun is very important to us. It is
the center of our solar system.
Remember that the sun provides us
with light and heat. It also powers
the water cycle and helps plants
make their food. The sun is the
biggest object in our solar system
and therefore has the most
gravitational pull. The sun’s gravity
is the reason all other objects
revolve around it.
