CENTER of our Solar System.
 Believe it or not the sun is not a perfect sphere. Many ridges are located
on the Sun’s outer core.
Temperature = Around 10,000°F at the surface and at the core it rises to
about 27,000,000°F!!
The Sun has no moons because it is a star.
A full day rotation is 26.8 days.
The sun does not have a full year rotation.
The diameter of the Sun is 1,390,000 KM

The sun is made up of carbon, nitrogen, and
oxygen  makes up 1.5% of the Sun.

The other 0.5% is made up of neon, iron,


99.86 of the Solar System is the Sun.

Light from the Sun takes approximately 8
minutes to reach Earth!

The Sun generates Solar Wind.

One millions Earths can fit in the Sun!

Every second the Sun loses 5 millions tons of
material!

If the Sun were to stop producing energy today,
it would take 50 million years to fully effect
Earth.

Based on the average life of a G2 star
the present age of the Sun is estimated
to be 4.6 billion years old. (Half way through its
lifetime.
