Neil Armstrong was the first human to walk on the lunar surface Earth viewed from the Moon Mars Astronomical Symbol for Mars False color (blue) shows where water ice is buried beneath the martian surface in this Mars Odyssey image Mars rover photographed its empty landing platform after it rolled onto the surface of Mars at Gusev Crater Mars has the largest volcanic mountain in the Solar System Mars could have large amount of water ice close to surface Red color of Martian soil is due to the presence of iron oxides Mars has two moons Named after Roman god of war Sphere like grains that once may have formed in water appear blue in this false color image taken by Mars rover Opportunity near its landing site Ares Astronomical Symbol for Mars False color (blue) shows where water ice is buried beneath the martian surface in this Mars Odyssey image Mars rover photographed its empty landing platform after it rolled onto the surface of Mars at Gusev Crater Mars has the largest volcanic mountain in the Solar System Mars could have large amount of water ice close to surface Red color of Martian soil is due to the presence of iron oxides Mars has two moons Named after Roman god of war Sphere like grains that once may have formed in water appear blue in this false color image taken by Mars rover Opportunity near its landing site More Facts and Figures Chances are that life may exist on Mars, but not likely in the form Hollywood would prefer Life would probably be as single or multi-cell organisms You should be able to dunk the basketball on Mars Its gravity is 1/3rd of Earth’s Gullies suggest that water has recently flowed on Mars At the Martian equator, the temperature at your feet will be like a warm spring day, but at head level it would be freezing Mars rover Opportunity landed near the ‘Endurance Crater’ back Jupiter Astronomical Symbol for Jupiter The king of gods in Roman mythology The most massive planet in our Solar System Four planet sized moons and many smaller moons (total = 62) Jupiter has the largest number of moons in the Solar System Atmosphere comprises of hydrogen and helium Jupiter’s ring system Mushtarie Astronomical Symbol for Jupiter The king of gods in Roman mythology The most massive planet in our Solar System Four planet sized moons and many smaller moons (total = 62) Jupiter has the largest number of moons in the Solar System Atmosphere comprises of hydrogen and helium Jupiter’s ring system More Facts and Figures Voyager 1 image of Jupiter’s Great Red Spot The Great Red Spot is a hurricane-like storm system Jupiter’s Great Red Spot is large enough to hold three Earths back Saturn Astronomical Symbol for Saturn Roman god of agriculture Galileo Galilei discovered Saturn in 1610 Saturn is 755 times larger than Earth Rings of Saturn extend hundreds of thousands kilometer Rings are made of mostly water ice and rocks Saturn has 47 known moons An ultraviolet image of Saturn’s ring show more water At the outer edge of the rings Kayvon Astronomical Symbol for Saturn Roman god of agriculture Galileo Galilei discovered Saturn in 1610 Saturn is 755 times larger than Earth Rings of Saturn extend hundreds of thousands kilometer Rings are made of mostly water ice and rocks Saturn has 47 known moons An ultraviolet image of Saturn’s ring show more water At the outer edge of the rings More Facts and Figures Saturn is less dense than water. It could float in a bathtub if a bathtub large enough for it could be built Cassini spacecraft image showing the true color of Saturn rings back Uranus Astronomical Symbol for Uranus The dark ‘polar hood’ of Uranus showing a veil of ice and dust Uranus is 2870.97 million km away from the Sun Uranus has 27 known moons The moons are mostly named after works of Shakespeare and Pope Named after the Greek supreme god Image from the Keck Observatory showing the ring of Uranus Urano Astronomical Symbol for Uranus The dark ‘polar hood’ of Uranus showing a veil of ice and dust Uranus is 2870.97 million km away from the Sun Uranus has 27 known moons The moons are mostly named after works of Shakespeare and Pope Named after the Greek supreme god Image from the Keck Observatory showing the ring of Uranus Neptune Astronomical Symbol for Neptune Voyager 2’s image of Neptune’s mysterious Great Dark Spot The clouds in the image have been estimated to be about 31 miles tall Neptune is 4.5 billion km away from Sun Neptune was located through mathematical prediction rather than direct observation Atmosphere comprises of hydrogen, helium and methane Effective temperature = -353 F Neptune has 13 known moons Named after the Roman god of sea Neptun Astronomical Symbol for Neptune Voyager 2’s image of Neptune’s mysterious Great Dark Spot The clouds in the image have been estimated to be about 31 miles tall Neptune is 4.5 billion km away from Sun Neptune was located through mathematical prediction rather than direct observation Atmosphere comprises of hydrogen, helium and methane Effective temperature = -353 F Neptune has 13 known moons Named after the Roman god of sea Pluto Astronomical Symbol for Pluto Pluto’s moon Charon is nearly half its own size – large! Named after the Roman god of the underworld Pluto is the smallest , coldest and most distant planet Pluto is mostly brown and is probably covered with methane frost Surface temperature = -387 to -369 F One known moon named Charon One Pluto year = 248 Earth years Pluton Astronomical Symbol for Pluto Pluto’s moon Charon is nearly half its own size – large!
