List the phrase & order of the planet from Sun to Space
• My = Mercury• Very = Venus• Educated = Earth• Mother = Mars• Just = Jupiter• Served = Saturn• Us = Uranus• Nine = Neptune• Pizzas = Pluto
List the phrase & order of the planets from smallest to largest!• Probe = Pluto• Magellan = Mercury• Mapped = Mars• V = Venus• E = Earth• N = Neptune• U = Uranus• S = Saturn• Jupiter
Mercury• Inner Planet• Terrestrial Planet• 0 moons• 0 rings• No atmosphere
(burned off by sun)• Widest
Temperature Range
• Cratered surface
Venus• Inner Planet• Terrestrial Planet• 0 moons• 0 rings• CO2 & Sulfuric acid in
atmosphere• Thick & cloudy
atmosphere• Greenhouse effect• Hottest Planet• Retrograde Rotation• Twin of Earth
Earth• Inner Planet• Terrestrial Planet• 1 moon• 0 rings• Oxygen & Nitrogen
atmosphere• 70% covered with
Water• Life• Tilted on Axis• Seasons
Mars• Inner Planet• Terrestrial Planet• 2 Moons• 0 Rings• Thin CO2• Tilted Axis• Seasons• Iron Oxide (Rust) -
Dusty• Red Planet
Jupiter• Outer Planet• Gas Giant• Many Moons• Rings• Hydrogen (H) &
Helium (He)• Largest Planet• Great Red Spot
Saturn• Outer Planet• Gas Giant• Many Moons• Most Rings• H & He• Least dense
planet – could float in water
Uranus• Outer Planet• Gas Giant• Many Moons• Rings• H & He & Methane• Blue-green in
color• Tilted on side
(90°)
Neptune• Outer Planet• Gas Giant• Many Moons• Rings• H & He & Methane• Blue in color• Discovered by
mathematical prediction
• Can switch places with Pluto – sometimes last planet from sun
Pluto• Outer Planet• 1 Moon (Charon) + 2
smaller ones• 0 Rings• Unknown Atmosphere• Scientists reclassified
as dwarf planet• Known as double
planet –Charon is more than ½ its size
• Like a terrestrial planet
Inner Planets vs. Outer Planets
Inner Planets
•Mercury•Venus•Earth•Mars
Outer Planets
•Jupiter•Saturn•Uranus•Neptune
Inner Planets vs. Outer Planets
• Small vs. Large• Rocky vs. Made up of Gases• 0-2 Moons vs. Many Moons• No Rings vs. Have Rings• Before AB vs. After Asteroid Belt• Varied vs. Mostly H & He
atmospheres atmosphere• Fast revolu- vs. Slow revolution
time tion time
Inner Planets vs. Gas Giants
In Common:• Revolve around the Sun• Rotate on axis• Elliptical orbits• All affected by their own inertia and the sun’s
gravity• Each planet has its own gravity• Shaped the same – like sphere• In the Milky Way Galaxy• Named after Roman Gods• All visited by a Space probe
How does Pluto fit in?More like a terrestrial
planet• Small• 1 Moon/2 smaller ones
discovered• No rings• Solid? Not made up of
as much gas1 Theory: Pluto could be
a moon that escaped Neptune’s gravity.
Why is Pluto a Dwarf Planet?Characteristics of a Dwarf Planet:
•Orbits the Sun & is not a moon•Has enough mass so its gravity pulls it into a sphere•Other objects are in its orbital path•Smaller than Mercury
Other dwarfs: Ceres, Eris, Makemake, & Haumea
