Mr. 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 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 

 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.

 1 st planet from the sun  Shortest revolution  Rotates retrograde (clock wise)  Much smaller than earth  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)

 2 nd planet closest to the sun and the planet before earth.  Terrestrial surface  Most like the Earth  Smaller than earth  2 nd 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)

 Most complex planet with every system- water, air, land and life.  5 th largest in solar system  23 degree tilt on axis  70 percent of earth is covered by water  Mostly 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

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

 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  5 th 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

 6 TH 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

 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

 7 th 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.

 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.

 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.
