The sun is the most important object in our solar system. It provides light and heat to Earth that allows plants to perform photosynthesis to grow and produce oxygen for humans to breathe. The sun is formed from hydrogen and helium, and its core temperature reaches 15 million degrees Celsius due to ongoing nuclear fusion. It is approximately 5 billion years old and will likely burn for another 5 billion years before exhausting its fuel.

2. Introduction:
The sun is the most
important start in
our solar system,
because it gives to
the Earth life
specially to the
plants.

3. PHOTOSYNTESIS
The rays of the sun are
important to the plants
because of the
photosynthesis. It helps
to the plants grow up
and it gives to the human
been oxygen.

4. WHAT IS THE
SUN?
The sun is formed from hydrogen and
helium.
The sun gives to the Earth heat and
light.

5. WHAT MAKES
THE SUN BURN
IS…
When the hydrogen and helium are
mixed make a fusion, and it
releases nuclear energy creating
heat in the sun. In the core is
concentrated all the energy due to
that fusion is developing
continually.

6. AGE: According with some studies,
the sun is 0.6 billion years and probably
will burn for another 5 billion years.
SIZE: The size of the sun is 0. 86
million miles in diameter and its weigth
is 2.000 trillion trillion tonnes.
TEMPERATURE: :The core of the
sun is hotter than the surface
SURFACE: 5.500 ◦C
CORE: 15 million ◦C
DISTANCE: The distance between
the Earth and the sun is 150.000 million
Km.

7. Do you know why the sky is blue?
When the rays of the
sun go through the
gaseous molecules in
the atmosphere release
different colors. The
frequency in some
colors are bigger in
that case blue color has
more frequency . For
that the light disperse
in the atmosphere
turning the sky blue.
