THE PLANETS OF THE MILKY WAY SOLAR SYSTEM

ORDER FROM THE SUN 1 My = Mercury 2 Very = Venus 3 Educated = Earth My Very Educated Mother Just Sent Us (Noodles) Nine Pizzas 1 My = Mercury 2 Very = Venus 3 Educated = Earth 4 Mother = Mars 5 Just = Jupiter 6 Sent = Saturn 7 Us = Uranus 8 Noodles or Nine = Neptune 9 Pizzas = Pluto ORDER FROM THE SUN

ALL THE PLANETS REVOLVE AROUND THE SUN. THEY ARE SATELITES OF THE SUN ORBIT = THE PATH THEY TAKE AROUND THE SUN

INNER AND OUTER Jupiter Mercury Main Belt Saturn Venus Uranus Earth Inner Planets Asteroid Belt Outer Planets Jupiter Saturn Uranus Neptune Mercury Venus Earth Mars Main Belt

THE PLANETS ARE NOT ALL THE SAME They differ in: COLOR SIZE SHAPE WEATHER POSITION LAYERS GASES ATMOSPHERE SATELLITES ROTATION REVOLUTION TILT

MERCURY Now that Pluto is gone it is the smallest planet Named after Mercury the swift messenger of the Roman Gods Very thin atmosphere or no atmosphere, so humans could not live there Takes 88 days to revolve or orbit around the sun The length of a day is 59 of Earth’s days No water Temperature range is -292 F to 842 F depending in if it is day or night No natural satellites or moons Mariner probe discovered its surface is similar to our moon

VENUS Almost as big as Earth-called our twin Has a hostile atmosphere full of carbon dioxide gas that traps heat Venus gets so hot during its day that it metal would melt like ice cream (869 F) Has thick rapidly spinning clouds that hold heat in and reflect light back making it look like a star in the sky Constant thunderstorms Rotates in the opposite direction of all the other planets Named after the Roman goddess of love and beauty Takes 225 days to revolve around the Sun A day on Venus is 243 Earth days long No water or satellites

EARTH Has an atmosphere full of nitrogen and oxygen so we can breathe Has liquid water Has life in the form of plants and animals

Temperature is cold and it has polar ice caps like Earth which may contain water The iron in the red clay dirt is what makes it look red Last if the inner planets Similar to Earth in length of day (24hrs7min), types seasons and tilt It takes 687 days to make a year on Mars Seventh largest Dry planet with thin atmosphere made of carbon dioxide. Named after the Roman god of war: Mars because it appears red and angry Two satellites: Phobos (fear) and Deimos (panic) companions to war god No life discovered on planet but scientists are hopeful there are microscopic life forms inside the rocks or ice caps that they might discover Has strong winds and seasons MARS

JUPITER Largest Planet-1000 Earths could fit inside Jupiter Its clouds in its atmosphere change color daily due to hydrogen and helium gas changes Red spot is swirling gas moving due to a very long hurricane Has lightning Has two rings No water, but oceans of liquid hydrogen Rotates quickly-every 10 hours (Earth rotates once every 24 hours) Takes 12 years to revolve around the sun Has over 60 satellites (63) Named after the chief, supreme Roman God similar to the Greek God Zeus who it was originally named after No life Average temperature is -302F

SATURN Second Largest Has a thin atmosphere that contains bands of clouds made up of helium and hydrogen The thousands of rings are made up of ice, rocks and particles of dust that orbit the planet 30 or more satellites named for the Titans Takes 30 years to revolve around the sun A day is 11 hours long on Saturn because that is how long it takes to rotate fully Water??? Probably not Life??? Probably not Named for the Roman God of agriculture who is also the father of Jupiter

URANUS It was discovered later than the others, 1781 and discovered by telescope not sight Has an atmosphere of hydrogen, helium and methane gas that gives it the blue-green color Water??? Probably not Life????? Maybe not Scientists believe it collided with another planet once which caused it to have a completely tilted axis. Has 11 rings made up of rocky chunks Day = 17 hours (rotation) Year = 84 Years (revolution) Named after Greek god of the sky Does not have a regular orbit. AXIS

NEPTUNE Not discovered until 1946 by telescope Scientists believe Neptune’s gravity is what pulls Uranus out of a regular orbit Named for the Roman god of the sea because of its color Also made up of hydrogen and helium and some methane to cause the blue color Neptune rotates (day) fully in 16 hours, but its atmosphere and clouds take two hours longer. That is unique. Has dark colored storms, one the size of Earth and is the windiest planet in solar system Takes 165 years to revolve or make a year Neptune is thought to have a layer of liquid water, methane and ammonia that changes to solid ice at times. Has 8 satellites and 4 rings

Expository-Informative-Factual Main Idea- All Planets are not the same Some don’t have atmosphere Some are bigger than other Some have life and others don’t Some don’t have water

Expository-Informative-Factual Main Idea- The planets were named after the gods One got its name from the German word for Earth One planet was named after the God of Agriculture Most were named after Roman Gods One was named after a Greek God
