    • Touring Our Solar System Interactive Power Point Project Erin Lewis ED 205-05
    • The Outer Planets The Asteroid Belt Comets The Sun Planet Earth The Inner Planets Our Solar System
    • The Solar System
      • Our solar system is about 4.5 billion years old
      • It has one star, (our Sun) and eight planets
    • The Sun
      • The Sun is one of
      • about 200,000 million
      • stars in our Galaxy!
      • It creates light and
      • heat through nuclear
      • fusion
    • The Inner Planets
      • Mercury
      • Venus
      • Earth
      • Mars
      • The four “Inner” Planets of our solar system are made of mostly rock and metal
      • They are also much smaller in size and mass compared to the “Outer” Planets
    • Mercury
      • Closest Planet to
      • our Sun
      • Smallest Planet in
      • solar system
      • No Moons
    • Venus
      • Second closest planet to Sun
      • Closest in size to Earth
      • Heavy atmosphere of Carbon Dioxide
      • No moons
    • Planet Earth
      • Earth is the only planet in our solar system that has liquid water and a breathable atmosphere
      • Over 70% of Earth is covered by water
      • Earth is the only planet in our solar system that can sustain life
    • Mars
      • Fourth planet from the Sun
      • Often called the “red planet” due to its red (rusty) soil
      • Two moons – Phoebos and Deimos
      • Been visited by three Earth “Rovers”
    • The Asteroid Belt
      • The asteroid belt is located between Mars and Jupiter
      • It consists of rocky bodies that range in size between boulders and small moons
      • It’s believed that this “belt” may once have been a planet that collided with another very large body in space, and broke into millions of pieces
    • The Outer Planets
      • Jupiter
      • Saturn
      • Uranus
      • Neptune
      • * Pluto
      • The Four “Outer” Planets of our solar system are made of gases, such as methane and hydrogen
      • They are much larger in size and mass than the “Inner” Planets
    • Jupiter
      • Largest planet in solar system
      • Fifth planet from the Sun
      • Known for its Giant Red Spot, a huge hurricane type storm in atmosphere
      • Has over 25 moons
    • Saturn
      • Sixth planet from the Sun
      • Known for its massive system of “rings”, made of ice and rock particles
      • Has at least 16 moons
    • Uranus
      • This bluish planet is made of mostly methane gas
      • Like, Saturn, it also has a distinctive ring system
      • It is the only planet that rotates flopped over on its side
    • Neptune
      • This gigantic planet also has a storm raging on its surface, just like Jupiter. It’s called “the great blue spot”.
    • Pluto
      • In 2006, astronomers decided that Pluto, by definition, is no longer a planet.
      • It is considered a “protoplanet”, or dwarf planet, due to its small size and strange orbit.
      • Pluto has one moon; Charon
    • Comets
      • Comets are like “dirty snowballs”. They are made of mostly ice and and rock
      • They usually orbit the Sun at great distances; much further out than even Pluto!
      • Sometimes, a comet is knocked out of this distant orbit. As it approaches the Sun, its ice begins to melt and forms its characteristic tail
    • Author’s Biography
      • My name is Erin Lewis, and I’m a senior at GVSU. My major is Group Social Studies, secondary education, with a minor in Earth/Space science.
      • This slide show represents a virtual tour of our solar system and its eight planets.
