Download The Sun

By Miss O.

Remember
“solar”
means
“things
having to
do with the
sun (in
Latin).

The asteroid belt is the region of the Solar System
located roughly between the orbits of the planets
Mars and Jupiter.
An asteroid is a
large rock in
outer space.
Some, like Ceres,
can be very large,
while others are
as small as a
grain of sand.

Halley’s Comet is the best-known
of the short-period comets, and is
visible from Earth every 75 to 76
years. We will see it again in 2062.
a celestial body
moving about the
sun, usually in a
highly eccentric
orbit, consisting of
a central mass
surrounded by an
envelope of dust
and gas that may
form a tail that
streams away from
the sun.

a transient fiery streak in
the sky produced by a
meteoroid passing
through the
earth's atmosphere; also
known as a shooting star

It just
seems
bigger to
us on
Earth,
because
it is the
closest
star to
the
planet
we live
on!

Remember: rotate
means “spin on its
axis.”

Yellow stars are made of gases: hydrogen and
helium.



In the form of heat
and light.
The energy comes
from the fusion of
atoms.
The sun is the
source of most of
the energy on Earth.
1. Corona
2. Chromosphere
3. Photosphere
*Convection Zone
*Radiation Zone
4. Core

Reaches far out into
space
Latin word for
“crown”
It is seen as a glow
around the sun
during a solar
eclipse.
Streams of particles
are called “solar
wind.”

2000-3000 km thick.
When it can be seen it is
reddish in color
This color is the origin of
its name (chromos
meaning ``color'').
The faint flow of the
chromosphere is due to
an emission spectrum
from hot, low density
gases emitting at discrete
wavelengths.


“sphere of
light”
It is the part
of the sun
that we can
see.
“surface of
the sun”

Convective or
Convection Zone
Radiative zone spreads
and heats atomic particles
 These gas particles “boil”

Radiative or Radiation
Zone

Energy from the core
heats just like a radiator
heats the air in a room

The center of the sun
Very, very hot
At the core, gravity pulls
all of the mass inward
and creates an intense
pressure. The pressure is
high enough to force
atoms of hydrogen to
come together in nuclear
fusion reactions -something we try to
mirror here on Earth.
