Parade of Planets

• An Imaginary Voyage Through the Solar System

3
Mercury

• Mercury is closest to the sun, therefore it is
  the hottest planet.
• It takes only 88 days for Mercury to go around
  the sun, but its day is 59 Earth days long.
• Mercury is only slightly larger than our moon.
• There is no atmosphere.
• Mercurys temperatures range from 800 degrees F
  in the sunlight to 300 degrees F in the dark.
• Mercury has no moons.

4
Venus

• Venus is nearly the same size as the Earth.
• Its atmosphere is mostly sulfuric acid and
  carbon dioxide.
• Temperatures are about 900 degrees F on the
  surface.
• A human being would be dissolved, roasted, and
  crushed by its atmosphere.
• Venus rotates once every 243 Earth days.
• It travels around the sun in 255 days.
• Venus has no moons.

5
Earth

• Earths atmosphere protects us form the suns
  heat.
• About 71 of the Earth is covered by water
• Located in the life zone of the solar system.
• Earth rotates once every 24 hours.
• It travels around the sun in 365 days.
• There is one moon orbiting Earth.

6
Mars

• Mars looks like a red star in the night sky.
• The rocks on the surface of Mars have a great
  deal of iron in them, rusting in the moisture
  of the thin atmosphere.
• Running water that was once on Mars is now frozen
  in the soil and polar ice caps of the planet.
• Mars is about half the size of Earth.
• The day is about the same length as an Earth day.
• There are 2 moons orbiting Mars, but they are
  very small and not shaped like a sphere.

7
Jupiter

• Jupiter is the largest of the planets.
• One cloud formation on Jupiter is the Great Red
  Spot a storm that has been raging at least 300
  years.
• The planet is made mostly of clouds of liquid
  hydrogen, which get extremely hot near the
  center.
• Jupiter swirls on its axis at unbelievable speed
  once every 10 hours.
• A year on Jupiter is equal to 12 Earth years.
• Jupiter has at least 16 moons.

8
Saturn

• Saturn has the largest system of rings.
• The rings are made of rock and ice orbiting
  around the equator of the planet.
• Saturns atmosphere is mostly liquid hydrogen and
  is constantly stormy.
• Saturn rotates in 10 hours and takes about 29 ½
  Earth years to orbit the sun.
• Saturn has about 20 moons, the largest being
  Titan.

9
Uranus

• Uranus has a thin ring system orbiting its
  equator.
• Four Earths could fit across the diameter of
  Uranus.
• A day on Uranus is about 17 hours long.
• One trip around the sun takes 84 years.
• Uranus has 15 moons.
• Ten of the 15 moons were discovered in 1986 when
  Voyager flew by.

10
Neptune

• The pale blue color is from clouds of hydrogen
  and helium.
• Neptune is 30 times farther from the sun than
  Earth.
• One year on Neptune is equal to 165 Earth years!
• Neptune has a hurricane raging in its atmosphere
  that forms a huge dark spot.
• There are eight moons orbiting the planet.
• Triton, the largest, has geysers that spew
  invisible nitrogen gas.

11
Pluto

• Pluto is probably made of ice. Not ice made from
  water, but ice made of frozen nitrogen.
• There are times when Pluto is closer to the sun
  thatn Neptune, making it the eighth planet for
  roughly 20 years at a time.
• The air is made mostly of nitrogen gas.
• The presence of nearby Charon draws molecules
  escaping from Plutos atmosphere to the surface
  of Charon.
