Mercury

• The closest planet to the sun.
• Has no water, air, or moons.
• Takes 88 days to revolve around the sun.
• The side of Mercury that faces the sun is burning
  hot and the side facing away from the sun is
  freezing cold!

5
Venus

• Venus is smaller than Earth.
• It is covered with thick, poisonous, acidic
  clouds.
• Venus is so hot, you would melt if you were
  standing on its surface.
• It takes Venus about 225 days to go around the
  Sun.
• It rotates backwards compared to the other
  planets!!

6
Earth

• Earth is one of the two planets in the solar
  system that has water on its surface.
• It takes Earth 365 days to revolve around the sun
  (thats a whole year)!
• Seasons are caused by the tip of the earths axis
  as it rotates around the Sun.
• The moon rotates around the earth and is
  sometimes called Earths Satellite.

7
Mars

• Mars is called The Red Planet because the sand
  on its surface is made of red iron oxide.
• Mars is a desert planet.
• There are craters, boulders, canyons, volcanoes,
  and clouds of red dust on Mars.
• Mars has TWO moons called Phobos and Deimos!
• It takes Mars 687 days to revolve around the Sun!

8
Jupiter

• Jupiter is the largest planet (1,000 Earths could
  fit inside of it!)
• There is no solid crust of land on Jupiter, it is
  made of gasses that swirl around.
• Rings of ice and dust circle around Jupiter.
• There are 12 MOONS!
• It takes Jupiter 12 years to revolve around the
  Sun.

9
Saturn

• Saturn is a gas planet just like Jupiter.
• The gasses on Saturn are lighter than water.
• Saturn has rings made of rocks, ice, and dust and
  they rotate around the planet.
• There are more than 20 MOONS!
• It takes Saturn 29.5 years to go around the Sun!

10
Uranus

• Uranus is a gas planet just like Jupiter and
  Saturn.
• It spins in a different direction than all of the
  other planets.
• Uranus is circled by rings.
• It takes Uranus 84 years to circle the Sun!!

11
Neptune

• Neptune is the last planet in our solar system
  that is made of gas.
• It is almost 3 BILLION MILES away from the Sun!
• It takes 165 years for it to circle around the
  Sun.

12
Pluto

• Pluto is the smallest known planet.
• Some scientists think that Pluto was once a moon
  of Neptune that broke away from Neptunes orbit.
• It is the last discovered planet since 1930.
• Every 248 years, Neptunes orbit is longer than
  Plutos!
• Plutos only moon, Charon, is almost as big as
  Pluto itself!
