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!

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.
