The
Sun
learn... about the interesting characteristics of our sun.
The
Sun
To understand the sun you must picture the inside. The
inside layers like the earth expect the sun has three layers
the Convection zone, Radiation zone, and the Core.
The
Core and the Radiation Zone
The sun's energy is produced in the core and on the earth
we know this because we feel the heat and see the sunlight.
When the energy is produced it travels outward to the radiation
zone where it is carried by particles called Photons.
Convection Zone
It takes millions of years for a photon to get to the next
layer the Convection zone. Once the energy get to the convection
zone it travels more rapidly by gases instead of Photons.
Gases and Bubbles at this layer mix like a pot of boiling
water. This bubbling is called granulation.
The Sun is a StarThe Sun is also an active star that
displays sunspots, solar flares, erupting prominences, and
coronal mass ejections. Life wouldn't be possible if there
was no sun. The sun is a giant, spinning ball of very hot
gas, and is fueled by nuclear fusion reactions.

The Core- The inner most layer of the sun.
The
Sunstar
The sun is a very hot ball of gases like most stars. The sun
isn't the brightest in the sky but finding one brighter is
very rare. One of the star that is brighter is Pollux which
is about 35 million light years away in the Gemini, of the
twins.
The
Milky Way/ Red Dwarfs
Most star are faint and cool stars called the red Dwarfs.
Most of the stars in the Milky Way galaxy are red Dwarfs 80
out of every 100 are RD (RD= red dwarfs).The nearest one to
the earth is beyond the sun just over a light year.
