3 Solar System, what in the world is it? Our solar system is built up of nine planets,the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Normally planets are made out of rocks and gases. The rings are made out of ice, and rock. their are 106,000,000,000 in the milky way galaxy.

4 The Sun the sun is so big it could hold a billion earths. If you were to light up the sun with light bulbs it would take 4,000,000,000,000 light bulbs. the core of the sun is a 20,000,000,000 degrees.

5 Mercury Mercury looks like our moon because it is a round crater of rock. The sun looks huge as it rises in Mercury. If you where on it you would die because of all the heat. The sunny side of Mercury is boiling hot but the night side is freeeeezing cold.

6 Venus A year on Venus is exactly 225 days and 365 earth days. Venus is the about the same size as earth. venus is the hottest planet even though Mercury is closer to the sun. the reason it is so hot is because the clouds on Venus trap the heat. Venus has acid storms so say, if a drop were to touch your skin it would go write through your skin.

7 Earth Earth is the third planet from the Sun. It has two things other planets don t have: life and oceans. Earth is tilted on its axis. The tilt causes the four seasons: spring, summer, fall, and winter.

8 Mars Mars has the largest volcanos out of all are planets. Mars is very dry it like a desert with red dirt. when mariner 9 a space probe, arrived on mars the whole planet was hidden by dust clouds.

9 Jupiter Jupiter is the largest planet in our Solar System. It is more than one-andone-half times as big as the other eight planets. The great red spot on Jupiter are 300 year old storms. The moon lo is always changing because its many volcanoes throw out new material from deep inside it.

10 Saturn Saturn has a faster rotation period than any other planets but Jupiter. Saturn orbits the sun at an average of earth years. Saturn s core is made out of rock and ice.

11 Uranus Uranus is the seventh planet from the Sun and it is the third largest planet. It was discovered by William Hershay. it orbits the sun every Earth years. It is 1.78 billion miles away from the sun. And it has 22 moons.

Neptune The outermost planet of the gas planets. Discovered by Johann Gottfried Galle on September 23,1846. Neptune orbits the sun every 165 year.

12 Neptune The outermost planet of the gas planets. Discovered by Johann Gottfried Galle on September 23,1846. Neptune orbits the sun every 165 year. There are 8 moon and 4 rings. Neptune has the strongest winds out of any other planets. The winds blows west ward opposite of the rotation. A day on Neptune is 16 hours and 6.7 minutes on earth.

13 Pluto Pluto is the smallest and farthest planet from the Sun. Space probes have visited every planet but Pluto. If you where on Pluto, its moon Charon would look much larger then our moon does, because Charon is really close to Pluto.

14 Asteroids there are million Asteroids,some Asteroids are as big as a truck and some are as large as a mountain. Asteroids travel in a ring around the sun, this ring is called the Asteroids belt and it can be found between Mars and Jupiter. Asteroids are big pieces of rock that failed to stay together to make a planet.

15 Meteors and Meteorites a.k.a shooting stars Meteors are not really stars, they are only burned up pebbles. So hers the system a pebble gets shot up into the sky hit the out skirts off the air Earth and get so hot they go shooting across the sky.

16 Comets There are probably billions of tiny comets at the edge of the Solar System. They circle the Sun far beyond the farthest planet. Sometimes one is disturbed and moves inwards towards the Sun. comet is often called a dirty snowball because it is made out of dust ice mixed together. The tail of the comet always points towards the sun.

17 Telescope Telescope make it easier to see far away objects. Here are some of the worlds biggest telescope they are in Hawaii, Russia, California, Canary islands, Chile, Arizona, and Australia. Telescopes are good use for looking at stars,black holes, space ships, planets and just for something to do. We probably would not know to much about space if we didn t have telescopes.

PROBES NASA makes some of the probes. Robot spacecraft called probes have explored all the planets except Pluto. Probes travel in space to take close-up photos and measurements.

18 PROBES NASA makes some of the probes. Robot spacecraft called probes have explored all the planets except Pluto. Probes travel in space to take close-up photos and measurements. They send the info back to scientist on Earth. Some probes circle planets taking pictures. In 1976, two Viking spacecraft landed on Mars to look for like. Two voyager probes left Earth in 1977 to visit the gas giant planets.

19 Men and women that went to space People who go into space are called astronauts, they go to space to do research so we can learn more about space. Some of those people are: Buzz Aldrin how went with Neil Armstrong, NEil Armstrong the first person to walk on the moon, John Glemm the first american to orbit the Earth, Kathryn Thornton who orbited Earth 79 times, and many more.

20 Dictionary celestial objects: objects that are in space. distance: An amount of space between to things or people. gravitational force: The space between two bodies in space causing a gravitational force. gravity: The force that attracts a body towards the center of the earth. mass: A large body of matter with no definite shape. satellite: An artificial body placed in orbit around the earth. scale: Size and distance are in the wright portion. stars: A fixed luminous point in the night sky that is a large remote incandescent body like the sun.
