Our 8 PlanetsMr. Smith

Made of mainly gases. Much larger than any planet in the solar

system. Creates the gravity needed to hold planets

in orbit. The sun is the only star in our solar system.

All other stars are in our galaxy outside our main system.

As you look into the night sky, your seeing our galaxy and solar system.

The Sun

The sun is made up of 6 parts; The Corona, Chromospheres, photosphere, Convective zone, radiative zone and the core.

When you look at the sun your seeing the Photosphere.

The Corona is the suns atmosphere The Convective zone is where the gases

circulate The core is where the gases are burning

Continued……Sun

Will the sun burn out or shrink? Scientist have found out that the suns

energy comes from nuclear fusion. Fusion is the joining of two atoms to create

energy. The energy created from hydrogen atoms

fusing creates helium atoms. It then gets sent into other layers and eventually reaches the surface in the form of light energy.

Sun

1st planet from the sun Shortest revolution Rotates retrograde (clock wise) Much smaller than earth Its atmosphere is made of Mercury is a terrestrial planet Terrestrial means the type of surface Mercury has little to no atmosphere and manly

composed of Oxygen, sodium and helium. Rotates slow about (173 earth days)

Mercury

Mercury

2nd planet closest to the sun and the planet before earth.

Terrestrial surface Most like the Earth Smaller than earth Atmosphere made of 2nd fastest revolution of all planets Covered by a layer of clouds that trap heat and

covered by volcanoes. Atmosphere made of carbon dioxide(soda’s) Venus rotates very slowly ( 243 earth days)

Venus- When a volcano meets a tornado!

Venus

Most complex planet with every system- water, air, land and life.

5th largest in solar system 23 degree tilt on axis 70 percent of earth is covered by water Mostly 0-100 degrees Atmosphere 78% nitrogen and 21% oxygen 3 layers of surface- Crust, mantle and core 365 days in year and 24 hours in a day

Earth- The 3rd rock from the sun!

Earth and moon

4th planet from the sun Sometimes called the Red planet and the

Greek name is god of war. Terrestrial planet Home of the largest volcano in the solar

system called Olympus Mons Contains water in polar ice caps 2 moons Smaller than earth Less gravity than earth ( because it is

smaller) 4th longest revolution Rotation is the same as the earth Atmosphere made of 95 percent carbon

dioxide

Mars

Mars

Mars and its moons

Largest of the Gas Giants Jupiter has 4 very large moons called the

Galilean Satellites. Jupiter has a Giant Red Spot made of hot

liquid like substance Greek name is King of the Roman Gods 5th longest revolution Very short rotation of 9 hours and 55

minutes Over 300 times bigger than earth Has more gravitational pull than any other

planet in the solar system Atmosphere is made of Hydrogen and

Helium

Jupiter

Jupiter

Jupiter's moons

6TH planet from the sun Atmosphere made of hydrogen and

helium It’s a Gas Giant Has very visible rings that extend out

from the planet Titian is Saturn's biggest moon and is

one of the biggest moons of any planet.

It takes Saturn 30 earth years to have 1 revolution around the sun

But its day is only 10 ½ hours. 95 times bigger than earth 3 Saturn's can fit into 1 Jupiter

Saturn

Saturn

Saturn’s Moons

Wobbles on its axis Sits on its side and rotates Has 11 rings 14 times larger than earth Takes 83 years to complete 1 revolution Atmosphere is made up of hydrogen, helium

and methane Methane Gas gives Uranus its color just like

Neptune Last planet in the solar system

Uranus

Uranus

Uranus Moon’s

7th planet from the sun Takes 165 earth years to orbit around the sun 1

time Atmosphere is made of Hydrogen, Helium and

Methane Gases Methane Gas is what give Neptune its pretty

color Has very light and thin rings (4 rings) Has a rotation period of 16 hours Has more gravity than earth because it is larger.

Neptune

Neptune

Terrestrial planets are known for their rough surfaces and solid structure.

There is little distance between each planet

Terrestrial planets are the smallest of all the planets and the closest planets to the sun

Terrestrial planets atmospheres are made up of Carbon dioxide, oxygen and nitrogen.

Terrestrial planets

Gas Giants are known for their composition of Gasses that make up the planets.

There is a lot of distance between each planet

Gas Giants are the largest of all planets and they are the last 4 planets from the sun.

They are known for their many moons, rings and brightest colors.
