The Solar System

   11th Grade Astronomy
        Mr. Gonzales
We will explore the following…

- The Seasons of the Earth
- Day and Night
- You will even have a chance to go to Space
  School for an introductory to the Solar System
  and each planet.
- The Inner Planets
- The Outer Planets
- Stars, Asteroids, Comets, and Meteors
Before we begin, you must
complete the following pre-test!
Now let’s get started!
What are the Seasons of the Earth?

-   Fall
-   Spring
-   Winter
-   Summer
What causes the Earth to have
              seasons?

The seasons of the Earth are caused by the

 following:

 - The revolution of Earth around the sun.

 - The tilt of Earth’s axis.

 - The intensity of sunlight on each region.

 - The angle of sunlight as it reaches Earth’s
Confused? Maybe this will help.


• Watch this video or further your
  reading.
• Perform this experiment at home.
  Almost any soft, round object can
  work.
What causes day and night?

• Day and night are caused by the rotation of
  the Earth on its axis.

• These links provide a more in depth
  explanation that may help.

• Keep in mind, that one Earth rotation takes 24
  hours.
Now, lets learn about each planet in
            our Solar System
• As you follow the information links to the
  planets, please be sure to take note of the
  orbit, rotation, atmosphere, and natural satellites
  of each planet.

• Let’s take a trip to Space School! Watch this video
  to get started.

• Now lets move on!
What are the eight planets in our
            Solar System?
• The planets are:
  –   Mercury
  –   Venus
  –   Earth
  –   Mars
  –   Jupiter
  –   Saturn
  –   Uranus
  –   Neptune
              » Follow each link to go to Space
                School, provided by Science.Discovery.com.
Having trouble remembering the order
           of the planets?
• Just use this acronym:
  –   My (Mercury)
  –   Very (Venus)
  –   Eager (Earth)
  –   Mother (Mars)
  –   Just (Jupiter)
  –   Sent (Saturn)
  –   Us (Uranus)
  –   Nachos (Neptune)
               » If you wish, you can follow each link to the
                 planet’s information slide. Continue to the
                 next slide to learn about the Inner Planets.
So what are the four inner planets?
• The four inner planets in order from the sun
  are Mercury, Venus, Earth, and Mars.

• Each of the planets can be seen here.

• The inner planets are relatively close to the
  sun, and all are very dense and rocky. Three of
  four of them have the atmosphere to produce
  weather.
What is Mercury like?
• Mercury is the smallest planet in the solar
  system, and is closest to the sun.

• Because of its proximity to the sun, temperatures
  can rise to as high as 806 degrees Fahrenheit!

• Mercury has a gray cratered surface which
  resembles that of the moon.

• Read here to find out all about Mercury.
Mercury is pretty cool. Here’s why…
• One day on Mercury can be both 59 days long and 156
  days long.

• There may be ice on Mercury. Although it is a sun-
  baked planet, there are regions of the planet that have
  never been heated.

• The European Space Agency is working on a mission to
  Mercury called BepiColumbo. 2 space probles will orbit
  the planet.

• Read here for 14 things you never knew about
  Mercury!
What about Venus?
• Venus is the second planet from the sun, and is
  known as the Morning star or Evening star.
• The surface of Venus is covered by volcanoes. As
  many as 167 volcanoes cover the surface, each
  100 kilometers across!
• Venus has a yellow atmosphere full of carbon
  dioxide and clouds of sulfur dioxide.
• Read more about Venus!
Venus is a crazy planet…
• The surface of Venus is often described as quite hellish.
• The thick clouds of Sulfur Dioxide produce the strongest
  greenhouse effect in the Solar System, making the surface
  of Venus hotter than that of Mercury.
• Atmospheric pressure is 92 times that of Earth. Standing on
  the Surface of Venus would be like going a kilometer
  underneath the surface of the ocean!
• Here are some interesting facts. You would enjoy to read
  more!
You think you know Earth?
• Earth is the third planet from the sun.

• Earth is the only planet in the solar system known to
  have life.

• Million of species live on Earth, and 71% of the surface
  is covered by water.

• Our atmosphere is composed of Nitrogen and
  Oxygen, and has a protective ozone layer to block out
  the Sun’s harmful rays. Read more to learn about your
  home planet.
Facts about planet Earth
• Earth formed approximately 4.54 billion years ago, and
  life appeared on its surface within 1 billion years.
• Earth is the densest and largest of the 8 planets in the
  solar system.
• The planet is expected to support life for at least
  another 500 million years.
• Here are some cool facts about your home planet
  Earth.
What about Mars?
• Mars is the fourth planet from the sun.

• Iron oxide on the surface of Mars give the
  planet its reddish appearance.

• There are volcanoes, craters, deserts, and
  polar ice caps, all on the surface of Mars.

• In 2008, the Phoenix lander directly sampled
  ice water from the surface. Read more about
  the famous red planet.
Crazy facts about Mars
• Mars has about a third of Earth’s gravity, which means
  you could jump about 3 times as high on Mars
  compared to Earth.
• Only 1/3 of missions to Mars have been successful.
  Scientists are led to believe that something strange is
  happening, like a Bermuda Triangle effect.
• Mars has two moons, and one is going to crash into it.
  Read more!
What are the four outer planets?
• Jupiter, Saturn, Uranus, and Neptune are the
  four outer planets.
• They can each be seen here.
• The outer planets are separated from the inner
  planets by an asteroid belt.
• Each of the outer planets is mainly composed of
  gas, and each has over a dozen moons.
What role does Jupiter play?
• Jupiter is the fifth planet from the sun in the solar
  system, and is the first of the outer planets.
• Jupiter is a gas giant and has two and half times
  the mass of all other planets combined.
• Jupiter is composed of Hydrogen, and a quarter
  of its composition is helium.
• Jupiter has a planetary ring system composed of
  dust. Read more here!
Lets learn more about Jupiter…
• The Earth can fit inside of Jupiter more than 1000
  times.

• The giant red spot on Jupiter is called “The Eye of
  Jupiter” and is where a giant storm has been
  raging for at least 300 years.

• Jupiter has 63 official moons and 12 unofficial
  moons.

• It only takes 10 hours to go from day to night on
  Jupiter. Read more here about this bizarre planet!
What is Saturn like?
• Saturn is the sixth planet from the sun, and is the
  second outer planet.
• Saturn is also a gas giant, and is the second largest
  planet next to Jupiter.
• It is assumed that Saturn has a similar internal
  structure to that of Jupiter, and is composed of
  Hydrogen and Helium.
• Saturn is approximately 30% less dense than water.
  Read more about this gas giant!
Some interesting things about Saturn…

• Saturn has around 60 moons.

• Scientists suspect that there is life near Saturn. Ice

  geysers have been discovered on one of Saturn’s

  moons, Enceladus.

• Saturn spins so quickly on its axis that the planet flattens

  itself out. Ready more about this craziness!
Which planet is next?
• Uranus is the seventh planet from the sun, and is
  the third of the outer planets.
• Uranus is considered an ice giant.
• Uranus is made of various ices, such as
  water, ammonia, and methane, and has an

  storms, with winds up to 600 miles per second. Read
  more about this intense weather!
A few crazy things about Uranus
• Hurricanes on Uranus have winds of up to
  2000 km/per hour.

• Neptune’s moon Triton is even colder, at 235
  degrees Celsius.

• Unfortunately, as of now, there are no plans to
  visit Neptune again. Read more about why
  NASA has made this decision.
You may have learned when you were
    a child that Pluto is a planet…

But Pluto is not considered a planet anymore. It
  turns out that there are countless celestial
  objects in orbit with Pluto that are the same
  size. Pluto is not a dominant gravitational
  body in the Solar System. Because of this, it is
  a Dwarf Plant. You can learn more about this
  recent change here.
As you gaze into the night sky, what
    celestial objects do you see?


  Lets take a moment to learn about the
         stars, asteroids, and comets.
What is a star?
• A star is a luminous ball of plasma held
  together by gravity.

• The nearest star to Earth is the Sun, which is
  the source of most energy on Earth.

• Read and view images of stars and
  constellations by following these links.
Ever wonder the difference between
     an asteroid and a comet?


          Let’s find out.
What is an asteroid?
• Asteroids are rocky remains from the
  formation of the solar system.

• Asteroids orbit the sun, and range from a few
  hundred feet in diameter to a few hundred
  miles.

• Follow the tutorial about asteroids from
  National Geographic.
What is a comet?
• Comets are cold chunks of rock and dusty ice
  leftover from the formation of the Solar System.
• A mix of gas and dust is pushed away from the
  comet by solar winds. So as the comet passes the
  sun and vaporizes, a long tail called a coma is
  formed.
• Follow the tutorial and learn more about comets
  from National Geographic.
How likely is it that an asteroid will
       crash into planet Earth?

• What this video, provided to us by the
  Discovery Channel.

• Or you may think you have it all figured out
  from Hollywood movies… Check out this
  video.
What is a meteor?
• A meteor is a sand to boulder sized object that
  is a piece of debris in the Solar system.

• A meteor that reaches Earth’s surface is called
  a meteorite.
