The Sun is a huge star at the center of our solar system that provides light and heat to Earth. It is about 100,000 km wide and composed primarily of hydrogen and helium. Through nuclear fusion, the Sun generates tremendous heat at its core of over 27 million degrees Fahrenheit. It accounts for 99.85% of the mass in our solar system and has allowed life to develop on Earth through its provision of warmth and illumination.

1. The Sun

2. What does the Sun do?
The Sun is a huge star in the center of our solar
system. The Sun provides the Earth with light and
heat so we and all the other living things on Earth
can Survive, like Humans, Animals, Plants, and
more. The Sun can Provide Electricity for our
Houses and power many things, using solar panels.

4. Fact #1 about the Sun!
The Sun is 100,000kms wide and tall! The Sun is a
huge star, But it’s the not the biggest thing in the
Solar System or Milky Way, they is way more stars!

5. Fact #2 about the Sun!
The Sun is Millions of Miles away from Earth.
Mercury is the closet to the Sun, Venus is second,
Earth, Mars, Jupiter, Saturn, Uranus and then
Neptune. Pluto used to be a planet but it is now
considered a ‘Dwarf Planet’ because is rotated
differently to all the other planets in the System.

6. Fact #3 about the Sun!
The Sun is formed from cloud of hydrogen gas and
dust, 5 billion years ago. The Sun holds 99.85% of
the mass of our solar system, 92% hydrogen and
8% helium, Core is 27 million degrees Fahrenheit
Nuclear reactions of hydrogen atoms being forced together
under high temperature and pressure to form helium
* heat is from nuclear reactions.

7. Fact #4 about the Sun!
The Sun is a huge Star, But it’s not the only Star in the
solar system or in space. There are plenty of Stars in
the solar system, and in space. Some of the stars
have been discovered but there are plenty of more to
discover. The stars in the solar system are very hot,
the temperature is more then 1000, 000 degrees-
Fahrenheit. The outer stars are more bigger, in fact
once we discover new ones, they are bigger and
hotter than all the other ones we had discovered

8. Fact #5 about the Sun!
People think that the sun is the color yellow or
orange but it’s really not. The Sun Star is the color
white. How is the sun white? Because they are
plenty of pollution and litter on Earth. The rubbish
will reflect on the sun in the sky then it will give it
an orange or yellow color to us, but if there was no
pollution on Earth the sun will be white to us.
