Download Inner and Outer Planets

Bellwork
What is the organization
created by the United
States government to
explore space?
Tuesday March 25, 2014
• Objective: SW learn
about the positions and
characteristics of the
inner planets.
Two Systems
1. Because of distance between them, the planets
are divided in two main parts
-Inner Planets and Outer Planets
2. Inner Planets
-
Mercury, Venus, Earth, and Mars
Terrestrial planets- surfaces are rocky and dense
All different from each other
The Inner Planets
• Mercury is small and rocky.
One day on Mercury is the
same as 58.65 Earth days.
• The temperature gets hotter
than an oven during the
daytime and colder than a
freezer at night.
• Mercury is the first planet in
our solar system. It has a thin
atmosphere.
• It is the fastest moving planet
in our solar system.
• It is 57.9 million km. from
the sun. 0 moons.
-The next planet is Venus.
-It is the second planet from the
sun.
-It is the hottest in our solar
system. The temperature is 870
degrees Fahrenheit.
-It is 108.2 million km from the
sun.
-Venus rotates very slowly. It is
known as the morning star or the
evening star (very visible on
Jan. 29) 0 moons.
Why is Venus Called Earth’s
Twin?
• Same Density and About the Same
Diameter
• Different Rotation and Temperature
What are the
different
types of
rotation?
-Prograde Rotation: is
counter-clockwise, so that
the Sun rises in the east and
sets in the west.
-Retrograde Rotation: a few
planets rotate in the
opposite direction, so that
the Sun rises in the west.
-The planets with retrograde
rotations are Venus,
Uranus, (the dwarf planet
Pluto too.)
-Earth is the third planet
from the sun.
-Earth is the fifth largest
planet in our solar system.
-Earth’s rotation is slowing
down slightly about one
second every 10 years.
-The Earth is 149.6 million
km from the sun.
-We think Earth is the only
planet with life.
-Mars is the fourth planet from the
sun.
-Mars’s nickname is the red planet
because it has red soil.
-Mars’s soil is dry, rocky, and
covered with iron-rich dust.
Olympus Mons, the largest
volcano in our solar system, is on
Mars.
-Some people say there was a
dried up river on Mars. 227.9
million km from the sun. It has
two moons.

Name the inner
planets in order.
Thursday March 27, 2014
• Objective: SW learn
about the positions and
characteristics of the
outer planets.
The Outer Planets
General
• Most of these Planets are
–
–
–
–
Mostly Gas
Massive Atmospheres
Solid Cores due to pressure
All have rings
• Are called the Gas Giants (but Pluto)
– Mostly made up of Hydrogen and Helium
• Pluto is more like inner planets then outer
planets
-Jupiter is the fifth planet from the
sun.
-Jupiter is the largest planet in our
solar system. Jupiter has 63
known moons.
-It has a giant red spot which is a
storm.
-Jupiter is so big that you could
put every planet from our solar
system in it if it were hollow.
-If you weighed 100 pounds on
Earth you would weigh 254
pounds on Jupiter. Jupiter is
480,000,000 miles away from the
sun.
-Saturn is the sixth planet from
the sun.
-It is the second largest planet.
-It has dozens of rings that are
made of ice and rock and they
can be as small as a fingernail
and as big as the size of a car.
-Saturn is made out of
hydrogen and helium. If there
was an ocean big enough to
hold Saturn it would float.
-Saturn has 60 moons.
-Uranus is the seventh planet
from the sun.
-It is the third largest planet in
our solar system. It has 11
rings and 27 known moons.
-Uranus is the only planet in
our solar system that spins on
it’s side.
-It is the size of 14 Earths. It
is 1,850,000,000 miles from
the sun.
-It is a frozen planet with a
molten core.
-Neptune is the eighth planet
from the sun.
-Neptune has eight narrow, faint
rings in clumps.
-Neptune was the first planet
whose existence was predicted
mathematically.
-Neptune is over 16 times the
size of Earth. A day on Neptune
is 19.1 Earth hours. One year
on Neptune is 164.8 Earth
years. Neptune is
4,546,000,000 miles from the
sun. 13 moons.
-Pluto is now considered a
dwarf planet and is no
longer counted as a true
planet.
-Each day on Pluto is 6.39
Earth days. A year on
Pluto is 247.7 Earth years.
Pluto is very cold. It can
be between -396° to 378°F.
-Pluto has 3 moons, and the
largest, Charon, is almost
the size of Pluto.
