1 The Planets Mrs. Cothery’s 7 th grade class

2 The Solar System  Our solar system is made up of eight individual and unique planets and is nearly five billion years old.  There are over 170 moons, thousands of asteroids and many dwarf planets.  Everything orbits around the sun.  The four planets closest to the sun are called terrestrial planets because they have solid rocky surfaces.  The four planets beyond mars are called the gas planets.

3 The Sun

4  The Sun is the largest star in the solar system.  It is about 333,000 times the size of earth.  It contains 99.8% of all the mass in the solar system.  It is 1.4 million kilometers wide.  The sun is filled with scorching hot gases.  The temperature is about 10,000 degrees Fahrenheit at the core.  The sun holds the solar system together, and gives it light, heat and energy.

5 Mercury

6  Mercury is the closest planet to the sun, and can reach temperatures of 801 degrees Fahrenheit.  It has very little atmosphere to trap heat, so the temperatures at night can plummet to - 279 degree Fahrenheit.  The sun looks up to three times larger on Mercury than in does on Earth.  It is the second smallest planet in the solar system.

7 Venus

8  From Earth, Venus is the brightest object in the night sky.  Venus is similar to Earth’s size.  It has a think, rapidly spinning atmosphere.  The surface pressure is 90 times of the pressure on Earth.  The atmosphere consists mainly of carbon dioxide.  The surface temperature can be over 880 degree Fahrenheit.  One day on Venus is equally to 117 Earth days.

9 Earth

10  The only known planet to support life.  Has a thin atmosphere that protects us.  We are about 93,000,000 miles away from the sun.  Our atmosphere consists of 78% nitrogen, 21% oxygen and 1% other ingredients.  Our atmosphere shields us from the harmful sun’s rays.  Our molten nickel-iron core gives us our magnetic field.  Our oceans are at least 2.5 miles deep.

11 Mars

12  Known as the red planet  Made up of a rocky surface  The surface is covered in volcano's, shifting tectonic plates and meteor impacts.  It has seasons that change it polar ice caps.  Mars often has large dust storms.  It is believed that 3.5 billion years ago Mars experienced great flooding.

13 Jupiter

14  The solar systems largest planet.  Jupiter atmosphere is made up of hydrogen and helium.  Jupiter has four planet size moons.  It is very similar to a large star.  Its four moons are called Io, Europa, Ganymede, and Callisto.  It has clouds made of ammonia.  Jupiter's surface does contain water.  It is famous for its great red spot, which is a huge storm that has been around for over 300 years.

15 Saturn

16  It is one of the large gas giants.  It is made up of mostly hydrogen and helium.  The yellow and gold banding is made by fast winds in the upper atmosphere.  Galileo was the first person to see Saturn.  Saturn's volume is 755 times greater that Earth.  Saturn’s rings are the most complex and extensive in the solar system.  Saturn has 52 known moons.

17 Uranus

18  Spins on an axis that mostly faces the sun.  The large amount of methane gas in its atmosphere give it the distinct bright blue color.  Uranus has 11rings  It is one of the large gas planets.  It atmosphere is made up of hydrogen and helium.  It magnetic field is tipped over.  Uranus has 27 known moons.

19 Neptune

20  The furthest planet in our solar system.  It also gets it blue coloring from the methane gas in its atmosphere.  Large storms are are common occurrence on Neptune.  It is nearly 2.8 billion miles away from the sun.  Its atmosphere extends to great depths, gradually merging into water and other melted ices.  The axis of Neptune’s magnetic field is tipped over bout 47 degrees.
