2. A Journey through Space! Have you ever wanted to visit space? If the answer happens to be yes then sit back, relax and enjoy. By Clara Loughran and Connor Mckinlay Part 2

3. The Sun The Sun is the star at the center of the solar system. It is almost perfectly spherical and has a diameter of about 1,392,684 km, around 109 times that of Earth. The Sun formed about 4.567 billion years ago. The Sun is now thought to be brighter than about 85% of the stars in the Milky Way. The surface temperature of the Sun is about 5504.85 o C.

4. Mercury Mercury is the smallest and closest planet to the sun. With an orbital period of about 88 earth days. Mercury's surface experiences the greatest temperature variation of all the planets, ranging from 100 K (−173 °C; −280 °F) at night to 700 K (427 °C; 800 °F) during the day. Mercury's axis has the smallest tilt of any of the Solar System's planets (about 1 ⁄ 30 of a degree). One moon was briefly thought to exist in the early 1970s, but it turned out to be misinterpreted data from a star. So mercury has no moons.

5. Venus Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. After the Moon, it is the brightest planet in the night sky. Venus is sometimes called Earth's sister planet because of their similar size and gravity. With a surface temperature of 735 K (462 °C; 863 °F), Venus is by far the hottest planet in the solar system. It has no carbon circle. Venus is thought to have had as much water as Earth in the past. A day on Venus is 243 Earth days.

6. Earth Earth is also known as the world and is the third planet from the sun. Earth was formed around four and a half billion years ago. During one orbit around the Sun, the Earth rotates about its own axis around 366.26 times. Trees make oxygen for the Earth and no other planet has oxygen. If Earth was 7 centimeters closer or further away from the sun then there would be no life on Earth.

7. Mars is the fourth planet from the Sun and the second smallest planet in the Solar System, after Mercury. The average annual temperature on Mars is cold, about - 81 o F (-62 o C). However, the temperature on Mars may reach 70 o F (about 20 o C) at noon at the equator in the summer. Mars is rocky and cold with polar ice caps of frozen water. Mars has two small moons, called Phobos and Deimos. Mars Exterminate People Exterminate People

8. Jupiter Jupiter is the fifth planet from the sun and is the largest in the Solar System. Jupiter is classified as a gas giant, because it is so large and is made up of mostly gas. The other gas giants are Saturn, Uranus and Neptune. Jupiter has at least 68 moons. 55 of the moons are very small and less than 5 km wide. The 4 largest moons are called Lo, Europa, Ganymede and Callisto. These 4 moons are called Galileo moons, because they were discovered by the Italian astronomer Galileo Galilei. Ganymede is the largest moon in the Solar System.

9. Saturn Saturn is the sixth planet of the Solar System. It is the second largest planet in the Solar System. Like Jupiter, Uranus and Neptune, it is a gas giant. Saturn has 62 known moons. The particles in the rings are made almost entirely of water ice, with just a small amount of dust. The moon Pan was discovered in 1990 by Mark Showalter.

10. Uranus Uranus is the seventh planet from the Sun in the Solar System. It is a gas giant. It is the third largest planet in the solar system. The planet is made of ice, gases and liquid metal. Uranus has 11 rings which are hard to see from earth. Uranus has 27 known moons. The five biggest moons are Miranda, Ariel, Umbriel, Titania and Oberon. Many moons have yet to be discovered. They remain a mystery. Uranus is covered in blue clouds. There are violent storms on the surface with winds that blow at 160 miles per hour. Scientists are studying the clouds to try and understand the storms on the planet.

11. Neptune Neptune is the eighth planet from the Sun in the Solar System. It is a gas giant. It is the fourth largest planet and third heaviest. Neptune has four rings which are hard to see from the Earth. It is 17 times heavier than Earth and is a little bit heavier than Uranus. Neptune also has the strongest winds of any planet in the solar system, measured as high as 1,300 mph. Neptune has a total of 14 known moons. The largest moon of Neptune is called Triton, discovered by William Lassell just 17 days after the discovery of Neptune itself.

12. Pluto (Now a dwarf planet) Pluto is not a planet any more because its small size made it a dwarf planet. Pluto has five moons. The first moon that was discovered was Charon which is near a quarter the size of Pluto, the second was nix, the third was Hydra, the forth was Kerberos and the fifth was Styx. Because Pluto is so small you would be very light if you visited. If you weigh 70 pounds (32 kg) on Earth, you would only weigh 4 pounds (2.5 kg) on Pluto. A dwarf planet is also known as a minor planet.

13. Minor Planets Minor planets can be dwarf planets, asteroids or Kuiper belt objects. The first minor planet to be discovered was Ceres in 1801, though it was considered to be a planet for fifty years. A planetoid is a large minor planet. Asteroids Asteroids are minor planets (most but not all) of which are located in the Asteroid belt between the orbits of Mars and Jupiter. Some asteroids have tiny moons like Ida which has a moon called Dactyl.

14. The Kuiper Belt The Kuiper belt is a region beyond the orbit of Neptune. After the Kuiper belt was discovered in 1992, the number of known Kuiper belt objects has added to over a thousand. The asteroids in the Kuiper belt are much bigger than the asteroids in the asteroid belt. Milky Way The Milky Way is fascinating because our moon travels round the Earth, the Earth travels around the sun and the Sun travels round the Milky Way. The Milky contains over 200 billion stars and is a spiral galaxy.

15. Mini Rocket Experiment! What you will need One empty 35mm plastic film canister and lid. One fizzing antacid tablet 5 ml of water Safety goggles The fizzing antacid tablet and 5 ml of water are the fuel source.

16. What to do 1.Put the Safety goggles on. 2. Break the antacid tablet in half. 3. Remove the lid from the film canister and put a teaspoon (5 ml) of water into the canister. 4. Drop the tablet half into the canister and snap the cap onto the canister (make sure that it snaps on tightly.) 5. Quickly put the canister on the ground CAP SIDE DOWN and STEP BACK at least 2 meters. 6. About 10 seconds later, you will hear a POP! and the film canister will launch into the air!
