• How many planets are in our solar system?
• There are nine planets in our solar system.

What will you learn?

• You will be learning some facts about each of the
  planets in our solar system.
• They will be presented starting with the planet
  closest to the sun, Mercury and ending with the
  planet farthest from the sun, Pluto.
• There will be a short quiz at the end.

4
Mercury

• The average temperature of Mercury is 800 degrees
  Fahrenheit during the day and -300 degrees
  Fahrenheit and night.
• Its terrain is heavily cratered with smooth
  plains in between.

5
Venus

• Venus is about the same size as the earth.
• It has 225 days in a year.
• Its atmosphere is very thick with carbon dioxide.
• It has a wide variety of surface structure due to
  volcanic eruptions.

6
Earth

• The length of the year is 365.26 days.
• The average temperature is 59 degrees Fahrenheit.
• The environment can be divided into four realms
  the magnetosphere, the lithosphere, the
  atmosphere and the hydrosphere.

7
Mars

• It has 687 days in a year.
• Mars has seasons similar to Earth, but much
  colder. During a mid-summer day, the temperature
  rarely climbs above freezing.
• The terrain consists of volcanoes, canyons,
  plains, and craters.

8
Jupiter

• Jupiter has many moons surrounding it.
• A year consists of 11.86 Earth years.
• It emits more radio noise than any other object
  in the solar system except the sun.
• It has an enormous magnet field that is a million
  times the volume of Earths magnetosphere.

9
Saturn

• Saturns year is the length of 29.46 Earth years.
• It has many rings that surround it with gaps in
  between.
• The upper atmosphere is composed mainly of
  hydrogen and helium.

10
Uranus

• A year in Uranus is 84.01 Earth years long.
• Its atmosphere consists of methane gas.
• Uranus also has rings surrounding it. There have
  been eleven identified.

11
Neptune

• Because of its long distance from the Sun, the
  atmosphere in Neptune is an average of -373
  degrees Fahrenheit.
• The blue-green color of the planet is due to the
  presence of methane gas in the atmosphere. Its
  atmosphere also contains hydrogen and helium.
• The length of one year equals 165 years on Earth.

12
Pluto

• Pluto is the smallest planet.
• It is also the farthest from the Sun, having an
  average temperature of -390 degrees Fahrenheit.
• It has an unusual orbit that sometimes takes it
  closer to the Sun than Neptune.
