Planets –
Mercury,
Venus, Earth,
Mars, Jupiter,
Saturn, Uranus,
& Neptune.
Dwarf Planets –
Pluto, Ceres,
Haumea,
Makemake,
Eris.
Asteroid Belt is
located between
Jupiter and
Mars.
If an asteroid
falls to Earth is
called a Meteor.
If it does not
burn up
completely
before it falls to
the ground it is a
Meteorite.
The Kuiper
(sounds like
viper) is made
up of icy
circular pieces
that have a
different
composition
than asteroids
or comets.
The Oort Cloud
contains a
trillion comets.
They can arrive
from
neighboring
solar systems.
A foreign
comet called
Sedna was
discovered in
2003.
Solar winds and
winds from the
Sun mix with
winds from other
stars.
This is known as
the Heliosphere,
or the border of
our solar system
and a
neighboring one.

The Sun is approx.
93 million miles
from Earth.
The distance of the
Sun to the Earth is
an Astronomical
Unit (AU).
The Sun is located
in the Orion arm of
the Milky Way
Galaxy.
The sun is
1,390,000 km in
diameter. The
diameter of the
Sun is over 100
times the
diameter of the
Earth.
The Sun is a
medium sized
star that is
halfway through
its lifecycle.
The Sun
appears larger
because of
how close it is
to Earth.
The mass of
the Sun in
about 2 x 10 to
the power of
30 kg.
A complete
Revolution,
or circle,
happens
once about
250 million
years.
The Sun Rotates on its
axis.
A spot on the equator
takes 25 days.
The north and south
poles takes 31 days.
The rotation of the Sun
and the Iron in its core
cause it to have a
strong magnetic field
that affects objects
within 3 million miles
of it.

The Sun
consists about
70%
hydrogen,
28% helium
and 2% of
metals, such
as Iron.
The
Temperature
of the surface
of the Sun is
about 5,000
degrees C.
The Core is
about
15,600,000
degrees C
The Sun is 4.5
billion years old.
Has about 5 billion
years left before
the hydrogen runs
out.
Nuclear Fusion is
when 2 protons
combine with 2
neutrons. The
energy is released
through its surface
and through
space.
