OUT OF THIS WORLD COMETSASTEROIDS, AND
METEOROIDS
By Mercury Jones Edited by __________________
2
In the Milky Way galaxy lies our solar system, a
region composed of the sun, nine planets, and
moons. Most people disregard the smaller
celestial bodies called asteroids, comets, and
meteoroids that fill our solar system.
3
COMETS
4
Comets, commonly known as Fiery Boulders, are
composed entirely of rock and do not have any
definite shape.
5
Comets appear to be fireballs of light zooming
through the sky. Comets, however, do not produce
their own light. Gas and dust particles reflect
the suns light.
6
In 1986, scientists all over the world awaited
the arrival of Halley's comet. This would be the
only opportunity in history to gather information
about such a comet, because its motion is
extremely unpredictable.
7
ASTEROIDS
8
Asteroids are fragments of rock with an irregular
shape that orbit the sun. They are too numerous
to be considered planets.
9
All asteroids can be found orbiting the sun
between Mars and Jupiter. This region is known
as the asteroid belt.
10
Due to the fact that asteroids do not differ in
composition, there can be no specific
classification system. Seen one asteroid, seen
them all.
11
METEOROIDS
12
Meteoroids, bits of rock and metal, are formed
from asteroids and comets. These small celestial
objects move throughout the solar system.
13
Meteors are shooting stars that fall from space
to Earth. Be sure to wear your safety helmet,
because each day millions of meteors are making
the trip.
14
Meteorites are meteoroids that pass through the
atmosphere and hit the Earths surface.
Meteorites are classified based on their
composition.
15
Students, Im having a hard time concluding this
PowerPoint. Please write a summary.
Thanks- Mercury
