POSITIONEARTHVENUSURANUSSATURNThe third planet from the sun 149,600,000 km from the sun

The second planet from the sun- 67,230,000 miles (108,200,000 km) from the sunThe seventh planet from the sun- 3,000,000,000 km from the sun

The sixth planet from the sun 1,503,000,000 km from the sun

- The gravity on Uranus is about 91% of the gravity on Earth - A 100 pound person would weigh 91 pound (45.5 kg)

- The gravity on Saturn is about 1.16 times the gravity on Earth- A 100 pound person would weigh 116 pound (54 kg)

EARTHVENUSURANUSSATURN- Earth has a thick atmosphere contain of nitrogen, oxygen, carbon dioxide and other gasses

- This planet has a very thick atmosphere contain of 96.5% carbon dioxide and 3.5% nitrogen- This planet has a thick atmosphere contain of 83% hydrogen, 15% helium, and 2% methane- This planet has a thick atmosphere contain of 75% hydrogen, and 25% helium

ATMOSPHERE

ORBITEARTHVENUSURANUSSATURN- A year on Earth takes 365 days ( to orbit the sun once)- A year on Venus takes 224.7 Earth days (it takes 224.7 days to orbit the sun once)

- A year on this planet takes 84.07 Earth years (to orbit the sun once)

- A year on this planet takes 29.46 Earth years (to orbit the sun once)

EARTHVENUSURANUSSATURNEarth is a terrestrial planet

Venus is a terrestrial planetUranus is a gas giant planetUranus is a frozen, gaseous, planet with a molten core

Saturn is a gas giant planet Saturn has no solid surface, it is a giant ball of gas, but it does have a solid inner coreComposition of the Planet and its AppearanceEARTHVENUSURANUSSATURN- The average surface temperature on Earth is 15% celcius- Its average surface temperature is about 467 celcius- Its average surface temperature is about -195 celcius

- Its average surface temperature is about -180 celcius

TEMPERATURE

EARTHVENUSURANUSSATURN- 1 moon, the diameter is about one quarter of the diameter of Earth- This planet has no moons

- 27 known moons, 5 of these moons are large and the rest are smaller

- 62 known moonsMOONS/SATELITE

EARTHVENUSURANUSSATURN- Earth has no rings - Venus has no ringsUrnaus is encircled by 11 belt of rings The rings are made up of black dust particles and large rocks

Saturn is famous for its beautiful rings Its rings made up of billions of pieces of rocks and dust, and Galileo was the first to observe Saturns rings

RINGS

EARTHVENUSURANUSSATURN- A person would asphyxiate in the poisonous atmosphere, be cooked in the extremely high heat and crushed by the enourmous atmospheric pressure A person would float, fly, sink and freeze because Uranus doesnt have solid surface and because of its very low temperature- A person would choke in the atmosphere, and freeze because of its very low temperatureHOW WOULD A HUMAN BEING FARE ON THE PLANET

EARTHVENUSURANUSSATURNEarth is the only planet known to support life in our Solar System Its tilted axis is 23.45 Venus rotates in the opposite direction of Earth, Venus rotates clockwise and Earth rotates counterclockwise A day on Venus is longger than a year on Venus Its tilted axis is 3.5Venus is the brightest planet in our Solar System, and its visible through naked eye

Uranus also rotates in the opposite direction of Earth, just like Venus- Its tilted axis is 97.77 giving it extreme seasons-It is believed that long ago a very large object smashed into this planet, the crash was so powerful that it completely changed the direction of its planetary rotation- Its tilted axis is 26.7SOMETHING SPECIALEARTHVENUSURANUSSATURN- - Venus was discovered by This planet was discovered by William Herschel on March 13, 1781No one knows who discovered Saturn, it was known since prehistoric time DISCOVERY OF THE PLANET

EARTH - URANUS- Both of these planets are terrestrial planetBoth of them have thick atmosphereBoth of these planets average surface temperature is above 0 celciusBoth of them have no rings

EARTH

SATURN I think that Earth is the best place to live because.......Earth has water and oxygenThe temperature is not too hot and not too coldIts distance from the sun is not too close and not too farIt has atmosphere to trap heat from the sun, and protect the Earth from radition, and other sky object which enter the Earth It doesnt have extreme seasons, due to the Earths axisEarth has the appropriate gravity for human to live
