The solar system consists of the Sun and everything that orbits it, including 8 planets, their moons, asteroids, comets, and other small celestial objects. The inner planets closest to the Sun are Mercury, Venus, Earth, and Mars. The outer planets farther from the Sun are gas giants Jupiter, Saturn, Uranus, and Neptune. Smaller objects like asteroids and comets also orbit the Sun.

Our solar system is made up
of:
 Sun
 Nine planets
 Their moons
 Asteroids
 Comets

3. InnerPlanets
The inner four rocky
planets at the center
of the solar system
are:
 Mercury
 Venus
 Earth
 Mars

4. Mercury
 Planet nearest the sun
 Second smallest planet
 Covered with craters
 Has no moons or rings
 About size of Earth’s moon

5. Venus
 Sister planet to Earth
 Has no moons or rings
 Hot, thick atmosphere
 Brightest object in sky besides sun
and moon (looks like bright star)
 Covered with craters, volcanoes, and
mountains

6. Earth
 Third planet from sun
 Only planet known to have life and
liquid water
 Atmosphere composed of composed of
Nitrogen (78%), Oxygen (21%), and
other gases (1%).

7. Mars
 Fourth planet from sun
 Appears as bright reddish color in the
night sky
 Surface features volcanoes and huge
dust storms
 Has 2 moons: Phobos and Deimos

8. OuterPlanets
The outer planets
composed of gas are :
 Jupiter
 Saturn
 Uranus
 Neptune

9. Jupiter
 Largest planet in solar
system
 Brightest planet in sky
 60+ moons, 5 visible from
Earth
 Strong magnetic field
 Giant red spot
 Rings have 3 parts: Halo
Ring, Main Ring, Gossamer
Ring

10. Saturn
 6th planet from sun
 Beautiful set of rings
 31 moons
 Largest moon, Titan,
 Easily visible in the night
sky
 Voyager explored Saturn
and its rings.

11. Uranus
 7th planet from sun
 Has a faint ring system
 27 known moons
 Covered with clouds
 Uranus sits on its side
with the north and south
poles sticking out the
sides.

12. Neptune
 8th planet from sun
 Discovered through math

 Great Dark Spot thought
to be a hole, similar to
the hole in the ozone
layer on Earth

13.  Most of the Moon's surface is covered with regolith, a
mixture of fine dust and rocky debris produced by meteor
impacts.
 The Moon has no atmosphere. But evidence from the
Clementine spacecraft suggests that there may be water
ice in some deep craters near the Moon's south pole.
 Most rocks on the surface of the Moon seem to be
between 4.6 and 3 billion years old.
 The gravitational forces between the Earth and the Moon
cause some interesting effects. The most obvious is our
ocean tides.

14. A meteor is a celestial event in which a number
of meteors are observed to radiate, or originate, from one
point in the night sky. These meteors are caused by streams
of cosmic debris called meteoroids entering Earth's
atmosphere at extremely high speeds on parallel trajectories.
Most meteors are smaller than a grain of sand, so almost all of
them disintegrate and never hit the Earth's surface. Intense
or unusual meteor showers are known as meteor
outbursts and meteor storms, which may produce greater than
1,000 meteors an hour.

15. Asteroids
 Small bodies
 Believed to be left over
from the beginning of
the solar system billions
of years ago
 100,000 asteroids lie in
belt between Mars and
Jupiter
 Largest asteroids have
been given names

16. Comets
 Small icy bodies
 Travel past the Sun
 Give off gas and dust as they
pass
