Introduction

• The Solar System is the sun and everything that
  orbits around it.
• The Solar System is made up of the 9 planets, the
  sun, comets, and meteors.
• The planets are separated into two groups The
  Inner Planets and The Outer Planets based on how
  close they are to the sun.

The Sun

• The sun is a star. It is the hottest, largest,
  and brightest object in our Solar System.
• The sun is mostly made up of Hydrogen.
• The sun is the start of our Solar System. It is
  very important to life on earth.

The 9 Planets

• The Inner Planets
• Mercury
• Venus
• Earth
• Mars

• The Outer Planets
• Jupiter
• Saturn
• Uranus
• Neptune
• Pluto

6
Mercury

• Mercury is bare and rocky.
• It has many craters and a lot of dust.
• Mercury is the closest planet to the sun.
• Mercury is the second smallest planet.
• It can get up to 784F and as cold as 297F.

7
Venus

• Venus has thick, yellow clouds made of poisonous
  Sulfuric Acid.
• Venus is mostly flat with a few mountains.
• There is very little water on Venus.
• Venus is the hottest planet. It can get as hot
  as 900F.

8
Earth

• Earth is the only planet that can have life.
• 70 of the surface is covered with water.
• Layers of gas surround the earth to protect life.
• The earth has one moon.

9
Earths Moon

• The moon is the second brightest object in the
  Solar System.
• The moon doesnt have an atmosphere.
• The moon has highlands and craters.
• FAQs about the moon
• Moon Madness

10
Mars

• Mars is known as the Red Planet.
• Mars has many channels and craters.
• People once believed life existed on Mars.
• It has the largest volcano in the solar system.
  It is called Olympus Mons.
• Mars has 2 moons.

11
Jupiter

• Jupiter is the largest planet.
• It is a ball of liquid, not solid like the first
  4 planets.
• Jupiter has many storms. The biggest one is
  called the Great Red Spot. These storms can last
  for years.

12
Jupiters Rings and Moons

• Jupiter is surrounded by rings.
• One ring is made up of pebbles, rocks, and
  boulders and another is made up of a ring of hot
  gas.
• Jupiter has 16 moons. The largest is named IO.
  IO has many active volcanoes.

13
Saturn

• Saturn is composed of gasses.
• Saturn is the 2nd largest planet in the Solar
  System.
• Saturn has clouds made up of frozen ammonia
  crystals.
• The clouds can blow up to 1,000mph.

14
Saturns Rings

• Saturns rings are over 160 thousand miles
  across.
• The rings are wide, but they are only 50 miles
  thick.
• The rings are not solid, they are made up of ice
  balls.

15
Saturns Moons

• Out of all of the planets, Saturn has the most
  moon. It has 20. Scientists think it may have
  more.
• Titan is the most interesting moon. It has a
  thick atmosphere and scientists think it may have
  water on its surface.

16
Uranus

• Uranus was discovered in 1781.
• Uranus is 4 times bigger than the earth.
• Uranus is made up of gasses.
• Uranus orbits the sun on its side. Why?
  Scientists believe it was hit by an object and
  tilted.

17
Uranus Rings and Moons

• The rings of Uranus werent discovered until
  1977!
• There are 13 rings and they are chunks of an
  unknown black material.
• Uranus has 15 moons.
• On the moon Miranda, there are 3 mile high cliffs
  of ice.

18
Neptune

• Neptune was discovered in 1846.
• Until then, many scientists thought it was a
  star.
• Strong, icy winds cover the planet in the form of
  storms.
• Neptune is made up of liquid Methane gas.

19
Neptunes Rings and Moons

• Neptune has 8 moons.
• Triton is the biggest moon.
• Triton is colder than any other object in the
  Solar System. It has a temperature of 391F.
• It also has ice volcanoes that shoot Nitrogen ice
  and gas.

• Neptune has 2 rings, however there may be 5.
• They are made up of tiny frozen pieces of
  materials.

20
Pluto

• Pluto is thought to be the last planet in the
  Solar System.
• We cannot get a clear view of Pluto because it is
  so far away.
• Pluto was discovered in 1930.
• Pluto has one moon, Charon. Charon is almost the
  same size as Pluto.

21
Asteroids

• Asteroids are mini planets. They are chunks of
  rocks and metals that circle the sun.
• The asteroids located between Jupiter and Mars
  are called the Asteroid Belt.

22
Meteors

• When pieces of asteroids break off, they become
  meteors.
• They streak through the sky toward earth.
• When the pieces hit the earth, they are called
  meteorites.

23
Comets

• Comets are patches of light that appear in the
  sky.
• Comets are balls of dirt that circle the sun.
• One of the main sources for comets is the Oort
  Cloud.
• The Oort cloud surrounds the entire Solar System!
