Planet Review!6th Grade Science
Mercury: What do you remember?
Mercury Closest to the Sun
Smallest Plant (used to be second smallest after Pluto)
Surface has many craters and high cliffs
No atmosphere
Varying temperatures has a very hot side and a very cold side
No moons
Mercury Fun Fact:
A year on Mercury lasts only 88 days!
Venus: What do you remember?
Venus Similar to Earth in size and mass – “Earth’s twin”
Has no water
Thick atmosphere made mostly of carbon dioxide –traps heat = HOTTEST PLANET
Droplets of sulfuric acid in the atmosphere give clouds a yellowish color
Surface has craters, cracks similar to faults, and volcanoes
Greenhouse effect makes it extremely hot
Has no moons
Venus Fun Fact!
Temperatures on Venus can reach 500 degrees Celsius or 932 degrees Fahrenheit!
Earth: What do you remember?
Earth: Atmosphere protects life
Surface temperatures allow water to exist as a solid, liquid, and gas
Has oxygen
Has one large moon
Earth Fun Fact!Earth’s atmosphere and magnetic field
protects the surface from objects in space!
Mars: What do you remember?
Mars:Surface appears red because of iron oxide in rocks
Has ice caps
Has channels that indicate that water has flowed on the surface before
Has many craters and inactive volcanoes
Often has dust storms
Has a thin atmosphere made up of mostly carbon dioxide
Has 2 small moons
Mars Fun Fact!
Iron oxide, (or rust!) gives Mars its bright red color
Mercury, Venus, Earth and Mars are called the INNER PLANETS! What do they all have in common?
Mercury, Venus, Earth, and Mars are called the INNER PLANETSThey are the closest planets to the Sun
They are WARMER and smaller than the other planets
All of them are made of solid, rocklike material
In their early years of formation, they were constantly struck by other objects in space causes them to have many craters
The inner planets have few or no satellites
Inner Planets: Mercury, Venus, Earth, Mars
My Mercury
Very VenusEasy EarthMethod! Mars
Jupiter: What do you remember?
Jupiter: Largest planet
Has faint rings
Atmosphere is hydrogen and helium; continuous storms swirl on the planet
Has 67 satellites
Jupiter Fun Fact!
Jupiter is 1,500 times bigger than Earth!
Saturn: What do you remember?
SaturnSecond-largest planet
Thick atmosphere is mostly hydrogen and helium
Has a complex ring system
Has at least 30 moons
Has the lowest density of all of the planets –so low that the planet would float in water
Saturn Fun Fact!
Winds on Saturn can blow at 500 meters per second.
Uranus: What do you remember?
UranusLarge, gaseous planet
Covered in a bluish fog
Faint gray rings made of graphite, the material used in pencils
Rotates on such a tilted axis that it looks like it is lying on its side
Atmosphere is hydrogen, helium, and methane
Has at least 27 moons
Neptune: What do you remember?
Uranus Fun Fact!
A day on Uranus only lasts 17 hours!
Neptune:
The last of the gaseous planets with rings that vary in thickness
Sometimes is father from the Sun than Pluto is
Methane in the atmosphere causes a bluish-green color
Has dark-colored storms in its atmosphere
Neptune Fun Fact!
Neptune takes 165 years to orbit the sun!
Pluto: What do you remember?
Pluto: Small, icy-rock dwarf planet with a thin atmosphere
Single moon, Charon, is half of its the diameter
Its orbit follows a curved ellipse path that is different from the rest of the planets
Sometimes is closer to the Sun than Neptune
Pluto Fun Fact!
Pluto sometimes moves inside Neptune’s orbit and is closer to the Sun than Neptune is!
The Outer PlanetsJupiter SaturnUranus Neptune
The Outer PlanetsAre far from the SunBecause of this, they are DARK and
COLD!Giants made up mostly of gas Each has moons and a ring system
The Outer Planets! Just JupiterSpeeds SaturnUp UranusNames!! Neptune
Put the Outer and Inner Planets together!
My Very Easy Method Just Speeds Up Names!!
Other ways to remember the planets in order!

My Very Evil Mummy Just Sat Upon Nathan’s Potty!
Are planets satellites?
Yes: Planets are satellites because they orbit around the Sun.
Are planets stars?
No! Why?
Planets are not stars because: They are smaller and cooler than stars
They cannot make light
Planets rotate at DIFFERENT SPEEDS and have different length days
For example, one day on Earth is 24 hours long, but one day on Venus is 243 Earth days long.
