Title: Planets


1
Planets
  • 6th grade Science

2
The Inner Planets
  • terrestrial planets- small, dense,
  • and rocky, like earth.

3
Mercury
  • closest to sun
  • one day on mercury is like 59 earth days.
  • It spins slower on its axis than earth.
  • the spin of an object in space is called a
    rotation.
  • one year is 88 earth days
  • revolution- the motion of a body as it orbits
    another

4
Venus
  • very similar to earth
  • same size, mass, and density
  • the sun rises in the west and sets in the east
  • Venus's rotation is opposite of ours.
  • has the hottest surface temperature of any
    planet.
  • the carbon dioxide in the atmosphere traps
    thermal energy from sunlight. greenhouse effect.

5
Earth
  • (if you are confused)
  • This is where we live ?

6
Mars
  • most studied planet, besides earth
  • Viking 1, Viking 2, and Pathfinder
  • spacecrafts launched and landed on mars
  • cold planet (13c - 77 C)
  • there is evidence of water on mars in the past,
    but now there is only ice.
  • volcanoes- Tharsis and Olympus Mons

7
The Outer Planets
  • Gas planets- dont have any known solid surfaces

8
Jupiter
  • largest planet
  • made of hydrogen and helium
  • Great Red Spot- a long-lasting storm
  • five NASA missions
  • Voyager 1, Voyager 2- sent back images of a faint
    line around the planet.

9
Saturn
  • second largest planet
  • rings of rock and ice
  • is made of hydrogen and helium
  • scientist believe Saturn is still forming!
  • all gas giants have rings, but Saturn's are the
    largest.

10
Uranus
  • is made of hydrogen, and methane gas.
  • featureless- no strong characteristics
  • tipped on its side.
  • Scientist believe that a large object hit Uranus
    and it tipped the planet over.

11
Neptune
  • has belts of clouds
  • has a dark spot like Jupiter

12
Pluto
  • smallest planet
  • furthest
  • large moon, Charon
  • made of rock and ice
  • only planet that has not been visited by NASA
