Jupiter
There are 8 planets in
the solar system.
Pluto is no longer
considered a planet.
From the sun the
order of the planets is:
Mercury, Venus,
Earth, Mars, Jupiter,
Saturn, Uranus,
Neptune
Jupiter is the largest
planet.
It is 5th from the sun.
It is considered a gas
giant. It has no solid
surface.
Saturn
Saturn is 6th from the
sun.
It is considered a gas
giant. It has no solid
surface.
It has rings around it.
Uranus
Uranus the 7th planet
from the sun.
It is considered a gas
giant. It has no solid
surface.
It has rings around it.
Neptune
Neptune is the 8th
planet from the sun.
It appears blue from
telescopes and is a gas
giant. It has no solid
surface.
It has rings around it.
Earth is the 3rd planet
from the sun.
Earth
It is a terrestrial planet
(rocky)
It can support life
because it has an
atmosphere, liquid
water and is close
enough to the sun for
light and warmth.
Venus
Venus is second from
the sun. It is similar to
the size of earth.
It is a very hot planet.
It is a terrestrial planet
(rocky)
Mars is 4th from the
sun.
Mars
It is a terrestrial planet
(rocky)
The atmosphere is thin
and it has canyons and
riverbeds.
Mercury is the closet
to the sun and is the
smallest.
Mercury
It is a terrestrial planet
(rocky)
It has lots of craters
and looks like our
moon.
Planets According to Size
Rotation
Revolution
Planets sorted in order
of size from largest to
smallest are:
1- Jupiter
2- Saturn
3-Uranus
4-Neptune
5-Earth
6-Venus
7-Mars
8-Mercury
The Earth rotates on
its axis every 24 hours.
The Earth completes
one revolution around
the sun every 365
days.
Seasons
Due to the tilt on its
axis, the Earth
experiences seasons
during its revolution
around the sun.
When the tilt is closer
to the sun it is spring
and summer. Farther
we experience fall and
winter.
Sun-Earth-Moon relationship
The Sun is a stationary
star. Earth rotates on
its axis and revolves
around the sun. The
moon rotates on its
axis and revolves
around Earth.
Sun
An average sized star.
It is 4.6 billion years
old.
It is about 110 times
bigger than the Earth.
The Moon
The moon is a small rocky
satellite. It rotates on its
axis and revolves around
the Earth about once
every 30 days.
It is ¼ the size of Earth.
Phases of the Moon
It has no atmosphere or
life, has very little water,
and extreme
temperatures.
There are 8 phases of the
moon and are based on
the moons position to
Earth and the sun.

Aristotle
Proposed that there
were planets and the
earth was at its center
Central region
composed of four
elements-earth, air, fire,
and water
Greek Philosopher and Scientist
Ptolemy
Proposed that the Earth
was the center of the
universe
Used math as a basis to
defend his theory
Greek Astronomer and Mathematician
Copernicus
Polish Astronomer
Believed that the earth
did not move; rather
other objects moved
around the earth in a
perfectly circular motion
Viewed the solar system
was centered around the
sun;
Believed that the earth
rotates on an axis and
revolves around the sun
Most people could not
comprehend a “moving”
earth and rejected his
theory
Disagreed with Ptolemy’s
theory
Galileo
Argued Aristotle’s
view
Believed in
Copernicus’ idea of
a “sun-centered”
universe.
Italian Physicist and Astronomer
Apollo Missions
Astronauts Neil Armstrong, Buzz Aldrin, Michael Collin were
members of the Apollo 11 Mission. Armstrong and Aldrin walked
on the moon. Collin maintained control of the mother ship.
1968 – 1971 NASA
made several
missions to the
moon and gathered
information. We
learned a lot about
the moon from their
missions and
studies and the
samples they
collected.
Gas Giants
the 4 largest
planets, made
mostly of gas:
Saturn, Jupiter,
Uranus, Neptune
Terrestrial Planets
rocky inner planets:
Mercury, Earth,
Venus, Neptune
