Our Solar System

  1. 1. E x p lo r in g o u rS o la r S y s t e m
  2. 2. C o n s t e lla t io n s b y A b b y C Do you ever see stars that make up shapes in the sky? They are called constellations. There are billions of stars in the sky. We can only see about two thousand. we can see more with a telescope or binoculars. There are clumps of stars all over the universe. They are called galaxies. We live in a galaxy called the milky way. A star is a big hot burning ball of gas made up of hydrogen and helium. Stars live for about 10 billion years! A long time ago people saw shapes made out of stars in the sky. They named then constellations and made up a story about each one. The north star is a special star. It is the only star that does not move. A long time ago sailors used the north star to find there way. The easiest way to find the north star is to find the star at the bottom left corner of the cup on the big dipper and keep on going up till you find the north star. Constellations and stars are cool things in the universe. I liked writing a report about them.
  3. 3. Super Stars by Abby WDo you know what stars are? Stars are big balls of burninggas and fire. They are found in galaxies. There is an infiniteamount of stars in the sky. More than all the sand from all thebeaches in the world. Stars live for ten billion years. That istheir life. Constellations are shapes made of stars. For example longago people would imagine lines connected the stars to makepictures in the sky. Those people were the Egyptians. Here aresome names of constellations. Orion. Leo ,Big Dipper, LittleDipper, Auriga and Delphinus. They also made up stories abouteach constellation.Stars and constellations are special because they light up thesky. There could not be life on a star because you
  4. 4. Venus by Adam Venus is a hot planet and it is the second closest to the sun and almost the size of Earth. It is called Earth’s twin. Venus has no moons or rings it take 255 days to orbit the sun. It is 7,521 miles and 12,101 kilometers across. It is made of iron. There is a volcano on Venus. Yes spacecraft have visited but it was crushed by the atmosphere on Venus. No there can’t be life on Venus because of the poisonous atmosphere. The surface is mostly flat. The atmosphere could crush you. Venus was named after an ancient Roman god of beauty. In conclusion venus interesting because of the poisonous atmosphere and the atmosphere could crush you.
  5. 5. P lu t o b y A la n Do you know what was the first dwarf planet? Pluto was. Pluto is located in the Kuiper belt. Pluto takes about 248 earth years to orbit around the sun. Pluto is a dwarf planet. Pluto is the farthest planet from the sun than Neptune. It is also very small that’s why it is called a dwarf planet. Pluto is the smallest planet in our solar system. Pluto is made out of ice and rock. Pluto’s surface looks like snow on earth. Another Dwarf planet called Eris is larger than Pluto. Pluto’s main moon is
  6. 6. Sun by AleahWhat is the sun. it is a big ball of burning gas. The sun is in themilky way galaxy. The sun is about five billion years old. It is onone of the arms. It is a middle aged star. Sunspots are darkspots on the sun. They look dark because they are cooler.Solar flares are explosions on the sun that send out hotparticles. The sun is made of hydrogen and helium gasses. Thesun is going to burn out in 5,000,000 years. It will turn into a redgiant and then a white dwarf. The sun is the most important part ofour solar system.
  7. 7. Comets by AnnieDo you know what travels trough space and never lands onplanets? I do, comets. Comets are small ice bodies with longstreaming tails. Comets seem to come from nothing with nowarning. In 1986 Halley’s comet was seen for the first timeEVER! You’re more likely to see a meteor then a comet.Comets are made of gas, ice and dust.. They travel around the sunin an oval orbit.. Comets are warmed up as they approach thesun. Halley’s comet appears once every 77 years. A Britishastronomer discovered that a comet tipped Uranus on itsside. Comets have no life on them. Comets can die but it cantake 14,000 years for a comet to die. No spacecraft haveever landed on a comet. I loved studying about comets.Thanks to our solar system.
  8. 8. Jupiter by AriDid you know that Jupiter is made out of gases?Jupiter travels around the sun every twelve Earth years.Jupiter is the 5th Planet It is on the other side of the asteroidbelt. Jupiter has a rocky center but the rest of this planet ismade of hydrogen gas. Jupiter is the biggest planet. Jupiterhas more than 60 known moons. Jupiter also has rings made ofdust and ice. Jupiter’s moons and rings all orbit the planet inthe same direction.I like Jupiter because it is big!

  10. 10. Do you know what is the second largest planet? Super Saturn by DaliaThat’s right Saturn is! Saturn is the third plantfrom our planet earth. Saturn takes 29 1/2 earthyears to orbit the sun 1 time because it is so faraway from the sun so it needs to make a biggerorbit then our planet earth does. Do you thinkthat Saturn looks the same when you look at it onthe first day of May, and you look at it again onthe first day of June again? Well if you think yesthat is correct. Saturn is made of gasses. It iscalled a gas planet. It is the sixth planet from thesun. Saturn is 74,900 miles across it is the secondlargest planet in our solar system. Saturn’s rockycenter is about the same size as planet earth.Saturn has at least 56 moon orbiting it. Saturn’sbiggest moon is named Titan it is 3,200 milesacross. Saturn also has an other moon it is namedEnceladus. The surface of Enceladus is coveredwith ice. Some chunks in Saturn’s rings are as bigas a house. The large dark stripes are emptyspaces between the rings. There are many stormson Saturn. One of them is called the DragonStorm because of its shape. The temperature atthe center of Saturn is 26,500 degrees farenheit.Saturn has winds that can travel one thousandmiles per hour! That is even faster than any windon Earth I think Saturn is amazing because I didnot know that it had so many rings – it has 1,000.
  11. 11. Black holes by DanielA black hole is the most bizarrre phenomenon that ever occurs in the universe.Black holes disobey every law of physics. A black hole sucks in anything thatgets too close including light , matter , time and gravity. They are so heavythat only zero gravity can move it. Imagine you took the earth and startcrushing it until it was the size of a golf ball, but it would weigh as much asearth . Black holes are usually about 24 miles across so use the mathformula of pi to imagine how much it would weigh. Black holes constantlyform and travel across the universe. Do not worry scientists have done mathand say that there are no black holes currently able to suck up earth. Theaverage black holes is about 24 miles across but some are monsters. Theclosest black hole is located at the heart of our galaxy. It is pulling stars outof their orbit and bringing them closer to it. That is why the center of ourgalaxy is so bright it’s surface is the edge of our universe. Black holes don’thave any rings or moons but they can have suns. There are an estimated200,000 ,000,000,000,000,000,000,000 formed a minute in our universe.The surface is called the event horizon (edge of the universe). Black holeshave 90,000 times gravity on earth . Too close to a black hole is about93,000,000 miles away. If you get within about that the hole wouldslowly suck toward it .When you get close to it very strange thingswould start to happen to you. Your legs would be getting pulled onmuch more than your head you would be stretched to the limit . Whenyour at the event horizon you would appear to be still but in reality youwould be inside the black hole. Very little is known about thesephenemona
  12. 12. Jupiter by DanielleHave you ever wondered about the red spot on Jupiter?Jupiter is the fifth planet in our solar system. It is the firstplanet beyond the asteroid belt. Takes 12 earth years to orbitthe sun. Jupiter is 480 million miles from the sun. It orbits thesun every 11.9 years. Jupiter is the biggest planet in our solarsystem. It has a rocky center but the rest of the planet is madeof hydrogen gas. Deep inside Jupiter the hydrogen changesinto solid rock and metal. Jupiter has more than 60 moons.Earth has only one. Jupiter also has rings made of dust. Theyboth orbit Jupiter. Scientists have used space probes to studyJupiter’s biggest moons. Io is covered with volcanoes. It has morevolcanoes than any other planet or moon in our sola system. Thesurface of Io is always changing. Europa is covered with a thicklayer of ice. Some scientists think there was water there.
  13. 13. Marvelous Milky Way by GavriDid you know our galaxy has awesome things to know ? If youwant to know then listen up. Do you know the name of ourgalaxy?Yes, you sure do .It is the milky way of course . It is called thatbecause it looks like a big blob of milk. Ancient Greeks thoughtso. The Milky Way is made up of over 1,000,000,000 stars. Thisgalaxy is called a spiral galaxy. We are on one of the spiralarms. The Milky Way is in a cluster of 36 galaxies. It orbitsaround the center of the universe.
  14. 14. Blue Uranus by JocyWho got hit by a rock? That’s right Uranus.Uranus is the 7 th planet from the sun. Uranus is bigger thanEarth. It is made of ice and rocks. it looks like a far away star.It looks blue from the methane gas. Uranus has 27 moons andat least 11 rings. Uranus is vary windy. the clouds move about400miles per Hour. Uranus spins on its side. Long ago a objecthit Uranus and it went on its side. It spins sideways. Uranuswas not discovered until 1781 because there wasn’t a powerfultelescope.Uranus is special because it spins on its side!

  16. 16. Pluto by JoshDid you know that Pluto is - 400 degreestemperature?Pluto is in the Kuiper Belt. It is the 9th planetfrom the sun. Pluto travels around thesun once every 248 Earth years. It is 1450 milesacross. It is a dwarf planet because it has anoval orbit and it is in the Kuiper Belt. Pluto ismade out of frozen water. Pluto’s moon isalmost the size of Pluto. Pluto has 1 moon andthe name is Charon. Pluto was discovered in1890 and they called it Planet X. In 1930 theynamed it Pluto. The New Horizons space probewas launched in 2006. It should reach Pluto in2015.

  18. 18. Saturn by MickeyDo you know the second-biggest planet in our solarsystem? Saturn is! Read on to find out more.Saturn travels around the sun once every 29 ½ Earthyears. Saturn is the sixth planet from the sun. Saturn isbetween Jupiter and Uranus. Saturn is a gas planet ofhydrogen gas. It is also the lightest in weight. Thecenter is plain rock, then liquid gas then hydrogen gas.Saturn has about 23 moons. It’s biggest moon is Titan.Saturn has many rings made of gas, dust and ice.Saturn has a lot of storms all over the planet. Thebiggest storm is called the Dragon Storm.I liked studying Saturn.
  19. 19. Marvelous Moon by MiraHi I am Mira Brown. welcome to the Moon center. Are you readyto take a tour of the Moon? Lets go!The Moon does not exactly orbit the sun. It orbits our Earth. Which inthis case, orbits the sun. Fun fact about the moon: it takes about 29 ½Earth days for the moon to orbit the Earth. The moon was formed about4.5 billion years ago. Our moon is more than ¼ of the Earth’ssize, but it could hardly be more different. It has noatmosphere, no life and no water. Over 3 billion years ago,thousands of meteorites bombarded it, which made craters.Only 12 people have been on the moon, during the time 1969 -1972. Our moon does not have volcanoes or storms. One of the12 people on the moon was Neil Armstrong. He went to themoon during 1969.I love the moon. I hope you do too!
  20. 20. Milky Way by NaomiDo you know which galaxy is home to Earth? It is the Milky Way.Astronomers believe that the Milky Way was formed out of alarge, round cloud of cold gas that collapsed on itself 16 billionyears ago! A huge group of stars is called a galaxy. Our galaxyis the Milky Way. Our sun is in the milky way galaxy. If youcould see the Milky Way from space it would look like a hugeSpinning pinwheel. The Milky Way galaxy has about twohundred Billion stars and countless other objects besides. Thesun is On one of the arms of the Milky Way. It’s a spiral galaxy.Everything in the Milky way orbits the center of the galaxy.Astronomers think there might be an enormous black hole at
  21. 21. Earth by NoyaDo you know why half of the earth is day timeand half of the earth night time? Because theSun is shining on one side! Earth is thirdfrom the sun and takes one year to orbitaround the sun. It also spins. It takes one dayto spin a whole circle. The Earth is made outof rock. Earth has life on it because we havewater. It takes 7,926 miles to walk across theEarth. We have one moon and it is the onlyplace man has visited. The surface is mostlymountains. The highest one is Mt. Everest.Billions of years ago Earth used to be reallyhot. It got colder and colder. It turned white,then it turned green, blue and white. Later ameteorite hit it and clouds covered it.There is life on Earth because there is wateron Earth.
  22. 22. Meteoroids by OmerWhat is the only object that flies and enters a planet? That’s right! Meteoroids.A meteoroid is a piece of metal and rock thatcame from the asteroid belt. Meteoroids werefirst asteroids but when two Asteroids bonktogether they become meteoroids. After ameteoroid bonks it doesn’t orbit the sun! Itflies through space to the planet earth. You canfind a meteoroid in space. When a meteoroidcrashes you can find the crash in a desserta grassy place or where dinosaurs lived. Whenthe meteoroid hit Earth the dinosaurs died.Large meteoroids are believed to come from theasteroid belt. Most small meteoroids are piecesthat have broken off from comets. But they’remostly large meteoroids. Meteoroids are made ofmetal rock. The meteoroids surface looks likebig craters that comets crashed into.Meteoroids have craters but don’t havevolcanoes or storms. There couldn’t be life on ameteoroid because it’s too small and there is nowater or air.Maybe one day we will see a meteoroid!
  23. 23. Mars by Peytonyou know if anyone walked on Mars? no, but space probeshave been there!! wouldn’t it be awesoMe to walk on Mars! it takes 687 earth days to orbit the sun. Mars is the closest tous.(earth). people could live on Mars in the future but it couldtake about 10,000 to 100,000 years! Mars has two Moons inorbit around it. Mars gets it’s reddish color froM rust in thesoil. Mars is alMost half the size of earth. Mars is a rock planet.Mars has a lot of crater s, Mountains, and canyons. Mars is thefourth closest to our star.(sun). Mars looks like a bright redstar froM earth. Mars has ice at its north and south poles.Mars is very cool to look at. Mars has a thin atMosphere sosunlight can get in but at night it is very cold. Mars has no ringsbut has 2 Moons. Mars’ Moons are phobos which Means fearand deiMos which Means panic. Mars has Mountains biggerthan Mt. everest. scientists believe that Martians used to liveon Mars because they fo und ice at its poles.

  25. 25. Neptune by TahelDo you know Neptunes surface is blue?The gases on Neptunes surface make Neptune’s surfaceturn the color blue. Neptune is the 4th biggest planet. It can fitabout 60 Earths in it. Neptune is 30,775 miles across. Windsfly around Neptune and they are up to 1,200 miles per hour.The center of Neptune is made of rock and ice. Neptune has13 moons. Neptune’s biggest moon is called Triton. It is about¾ the size of earth’s moons. Neptune is cold!
