1. Welcome everybody, to the planetary tour of all the planets. This will be an amazing journey to view things you have never seen before. First we will visit Mercury, Venus, Earth and Mars. Then we would visit Jupiter, Saturn, Uranus, and Neptune. There will be interesting facts about celestial bodies such as, the Oort cloud, dwarf planets, and the Asteroid Belt, which separates the terrestrial planets from the Jovian planets. So get ready, buckle your seat belt and get ready for a jam packed, adventurous tour of the planets!!!!!!!!

2. The Sun The sun is a star all plants revolve around. The sun is named after the sun god Apollo. The Greeks thought Apollo carried the sun across the sky is his chariot. But we know that the sun is not drawn by a chariot. The Greek astronomers also thought the planets revolved around Earth. That was called the geocentric theory, but the heliocentric theory is that the planets revolve around the sun. Nicolaus Copernicus developed this theory. Without the sun Earth would be a dark and dreary place to live. Food and crops would spoil and humans would starve from hunger. This is why the sun is important to all mankind. Apollo in his sun chariot The sun

3. MERCURY Mercury is the 1st planet near the sun. Mercury is 1 of 4 terrestrial planets in the solar system. Mercury got its name from the messenger god, formally known as Hermes. The planet also got its name because of its speedy orbit around the sun. Markings on Mercury’s surface show that its still shrinking .

4. MERCURY ELEMENTS Mercury is made of 70% of metallic and 30% of silicon. material. This planet has many craters and a dangerous atmosphere. Mercury’s craters Silicon in Mercury

5. SPACE PROBES The Mariner 10 and Messenger are 2 space probes that have visited Mercury. The Mariner 10 was orbited around Mercury for a year. This probe mapped 45% of Mercury’s surface. The 2nd probe to visit Mercury’s surface was the Messenger. The Messenger orbited around Mercury in March 2011. The Messenger will continue mapping the rest of Mercury surface.

6. VENUS Venus is the 2nd planet from the Sun. Venus is also the second terrestrial planet. The Greeks named the planet Venus, after the Greek goddess of love and beauty because of its shining beauty at night. This planet is sometimes called Earth’s sister planet because of its similarity in size, bulk, and gravity. Venus is also a place of extreme temperatures and very cold temperatures. Venus Venus Venus the goddess

7. VENUS’S ELEMENTS Some of the elements that make up Venus are: iron, sulphuric acid, and boiled water in the surface. Iron in Venus’s surface

8. VENUS’S EXPLORATION PROBES There have been 40 probes to orbit around Venus but the most recent ones are: Magellan 4, Venus express, and Planet c. The Magellan 4 orbited around Venus for 4 years, the Venus express in 2006,and the Planet c in 2008. The Venus Express The Magellan 4

9. EARTH Home sweet home!!!!! Earth is the 3rd planet from the sun. Earth is also the 3rd rocky planet in the solar system. This planet gets its name from the Greek goddess Gaia. Earth is the only planet with life.

10. EARTH’S ELEMENTS

11. America’s manned missions On February,20 1962 John Glenn attained the first ever orbit around Earth in the friendship 7. This was an amazing feat for the Americans because the Russians did not orbit Earth first. In 1997 John became Ohio’s senator for 4 consecutive terms. A year and a half later John enlisted in the Space shuttle discovery mission STS-95. This made John the oldest person in space at age 77. Senator John Glenn. The Friendship 7 John as an astronaut.

13. MARS THE RED PLANET Mars is the 4th terrestrial planet near the sun. This red planet attained its name from the war god Mars because of its blood-red stain. Mars gets this stain from large quantities of iron oxide in its surface.

14. MARS ELEMENTS Mars elements consist of 10 plentiful elements in the crust. These elements are: oxygen, silicon, iron, magnesium, calcium, sulphur, aluminum, sodium, potassium, and chlorine. Silicon crystals Aluminum crystals sodium Potassium crystals

15. MARS MOONS Mars has 2 asteroid like moons. These moons are named Phobos and Deimos. Phobos is the largest moon of Mars and Deimos is the smallest. Astronomer Asaph Hall discovered both of these long sought moons in 1977. Deimos was founded on August 12, and Phobos was founded on August 18 of 1977. Phobos rises in the west and sets in the east, while Deimos rises in the east but very slowly. Deimos ,Mars moons Phobos ,Mars moon

16. Mars exploration Probes Mars is a place of mass exploration probes including probes, rovers, and landers. 2/3 of the orbiters to Mars have failed in exploring Mars but there have been many successful missions also. The most current missions is the Curiosity in 2011, Phobos-Grunt mission, also in 2011. In 2013, Nasa plans to send Maven, a rover, to send information about Mars atmosphere. Hopefully , Nasa will, one day be able to send humans into Mars…….. Curiosity Phobos-Grunt Maven

17. CERES/ASTEROID BELT ASTEROID BELT The asteroid belt acts as a dividing line between Mars and Jupiter. It is a space of asteroids and bits of rock. More than 7000 asteroids have been discovered! The largest asteroid is Ceres. Ceres contains 25% of the mass of all the asteroids combined. That’s one large asteroid!

18. JUPITER, THE GAS GIANT What’s red ,brown, and stinks all over? Jupiter, of course!! Jupiter is the biggest of all the planets in the Solar System. A suitable name for the biggest planet would be the king of gods, so the planet was named Jupiter. Since Jupiter is a gas giant it is made of gas. This is like a balloon enveloping Jupiter in a cloud of gas. The gas is made of hydrogen and helium and small amounts of methane and water vapor. Jupiter also has rings like Saturn and Uranus. The rings are made of dust and tiny pieces of rock which makes Jupiter’s rings dark. In 1664 Robert Hooke, an english scientist discovered the great red spot on Jupiter. The Great Red Spot is an anti-cyclonic storm on Jupiter. The storm is so big that 3 planets the size of earth can ft in it. That’s really big!!!!! JUPITER The Great Red Spot

19. Jupiter’s Elements Jupiter is mainly composed of hydrogen with a quarter of the mass being helium and methane mixed in therefore making it an un-solid surface to walk on. Jupiter may also contain a core of heavier elements.

20. Jupiter’s moons Jupiter has 63 moons, making it a record breaker for having the most moons by a planet. The biggest of them all are known as the 4 galilean moons. They are Io, Ganymede, Callisto, and Europa. IO CALLISTO GANYMEDE EUROPA

22. Ganymede is the biggest moon in the Solar System. Scientists believe there is a salt water ocean underneath the crust in between the ice layers.

23. Callisto is the 3rd largest moon in the Solar System. It is heavily craterous and very old.

25. Saturn, The Great Ringed Wonder Saturn is the 6th planet from the sun. It is the 2nd largest planet in the Solar system. This great, ringed beauty is named after the Roman god Saturn. It is a gas giant along with Jupiter, Uranus and Neptune. These 3 planets plus Saturn are called the 4 Jovian planets meaning they are like Jupiter. For many years Saturn’s rings have interested astronomers. These rings are made entirely of ice and are very small. Although mirror-like images from the rings increase Saturn’s brightness we cannot see them from Earth without help.

26. Saturn’s Elements Saturn elements consist of hydrogen , ammonia, helium, methane, and carbon. The core is a mixture of iron, silicon, and nickel with metallic hydrogen and finally an outer layer of gaseous substance. Carbon Silicon Nickel Iron

27. Saturn’s moons Saturn’s moons are mostly made of rock and ice. This planet has more moons than any planet in the Solar System. More than 62 known moons with Titan being the largest. Titan is the 2nd largest moon with features somewhat like a planet. Titan was named the gods before Zeus’s reign . Titan is the only planet with an thick, nitrogen, atmosphere and seasons. Titan , Saturn’s moon. It looks like an orange!

28. Nasa has sent 4 space probes to visit Saturn. These missions are Pioneer 11 in 1973, Voyager 1 in 1980, Voyager 2 in 1981. These missions were flybys but the Cassini-Huygens orbited Saturn in 2004 and is still sending info today. Exploration probes Pioneer 11 Voyager 2 Voyager 1

30. Scientstsbelieve the reason for this strange tilt is because something hit Uranus and knocked it on its side.

31. Uranus is the 7th planet from the sun and the 3rdjovian planet.

32. William Herschel discovered Uranus in 1781.

33. It is named after the Greek god Ouranos meaning father of the skyUranus’ ring system was the 2nd discovered after Saturns, The rings are made of dark particles. Presently 13 rings are known, the brightest being ring E.

34. Uranus Elements Uranus elements consist of a mantle rich in water, ammonia, helium, hydrogen and methane. The methane gives Uranus its blue color. The methane absorbs sunlight near the red end of the spectrum, then the left over colors are near the blue end of the spectrum. The blue colors are not absorbed by the methane which enables us to see the blue.

36. Miranda is the smallest of all Uranus’s moons. It is named after the lady in Shakespeare’s The Tempest. Miranda was discovered in Febuary 16, 1984 by Gerard Kuiper. It looks like a broken dish glued together wrong.

37. Oberon is the 2nd largest moon of Uranus’s moons. It was discovered by William Herschel in 1787. It was named after the fairy king in Shakespeare’s The Tempest.Miranda the moon Umbriel the moon Miranda, tempest Oberon Oberon fairy king

38. Uranus exploration probes The Voyager 2 is the only rover to explore Uranus’surface. The closest it got to Uranus was in August 20, 1977. The rover found 10 unknown moons, studied its cold atmosphere, and found 2 new rings in its ring system. There have been many missions planned to go to Uranus but none have been achieved.

39. Neptune, The Blue Wonder Neptune is the last of all the Planets and is the farthest from the sun. This planet is named after the sea god Neptune. Neptune is named correctly because the sea is blue and so is Neptune. Neptune was discovered in September 23, 1948 by JohanneGalles.

40. Neptune’s elements Neptune’s elements are simillar to Jupiter and Saturn. Neptune is composed of hydrogen and helium with traces of nitrogen and methane. The methane gives Neptune its blue color like Uranus.

41. Neptune’s Moons Neptune has 13 known moons ; the largest is Triton. William Lassel discovered Triton just 17 days after finding Neptune! Triton is named after the sea god Triton. It is a deep frozen world that has geysers shooting out gas and dust. after finding Neptune! Scientist also found that Triton captured than formed into place by Kuiper Belt.

42. Neptune’sExplorationProbes On August 25, 1889 the voyager 2 made a flyby of Neptune. Since the Neptune was the last planet Voyager 2 go as close to Neptune’s moon Triton. During the mission it took 246 minutes to send Earth the information!!!!!!! I know I wouldn't be able to wait that long if I were a scientist!

44. The Oort cloud is a spherical shaped cloud of comets. Astronomers believe the cloud is the remains of the Solar Nebula that collapsed to form the Solar System. The cloud may extend to the sun’s star neighbor Proxima Centauri.Kuiper belt Oort cloud

47. Space Race Russia launched the Sputnik 1 on Oct. 4,1957. The Sputnik 1 was the 1st artificial satellite in space. On April 12, 1961, the 1st man to enter space was a Russian, named Yuri Gagarin. America fought back by placing the 1st man on the moon. Neil Armstrong was the 1st man on the moon.

48. In Taylin’swords….. One of our greatest presidents, John. F. Kennedy once said, “America has tossed its cap over the wall of space.” This statement meant that Americans have climbed over huge obstacles to go to space. Despite the obstacles, the rewards are great. One of the many rewards of going to space are that by discovering planets you can discover a new plant life that could cure diseases. Another advantage of continuing to explore space is the knowledge gained. The knowledge of space is interesting and priceless. If we do not continue exploring space kids with dreams of going to space will never dream. It is important we continue to search for new galaxies. By finding new galaxies, the world can find about our ever growing solar system. Another advantage to space exploration is going to Mars, astronauts can bring back Mars minerals. These minerals can be used to build pipes, which would pay for the expensive shuttles launches. By continuing to go to space, America can reap rich benefits and continue to throw new “caps over the walls of space.”
