Transcript of Science Planets

http://solarsystem.nasa.gov/index.cfm Our Solar System Notice: This model is not in scale, the distances/sizes of the planets and sun were altered to fit this screen. Inner Planets Outer Planets Bibliography There are 4 Inner Planets, Mercury, Venus, Earth, and Mars.They are closer to the sun and are more rocky in composition. They are a lot smaller than the Outer Planets and have very few to no moons. These planets have no rings around them. http://www.universetoday.com/33059/inner-planets/ Mercury Characteristics http://solarsystem.nasa.gov/planets/charchart.cfm Moons: None
Rings: None
Distance from Sun (km): 57 909 227km
Rotation period (Earth days): 58.646 earth days
Orbit period (Earth years): 0.2408457 earth years
Density of Planet (g/cm ): 5.427g/cm

Major Atmospheric Contents: No Atmosphere
Life forms: None 23 3 3 Cool Fact! http://science.nationalgeographic.com/science/space/solar-system/mercury-article.html Q: Does Mercury have an atmosphere? A: No Mercury does not have a atmosphere. Instead it has what we call an exosphere which is made of atoms blown of it's surface by solar winds and micro meteoroids. And because of Mercury's high surface temperature, the atoms very quickly escape into space. Venus Characteristics Moons: None
Rings: None
Distance from Sun (km): 108 209 475km
Rotation period (Earth days): -243.018 earth days

Mass (kg): 4.8673 x 10
Surface temperature (Celsius): 462Celsius
Major Atmospheric Contents: Carbon Dioxide, Nitrogen
Life forms: None 3 3 24 Cool Fact! http://solarsystem.nasa.gov/planets/compchart.cfm?Object1=Moon&Object2=Moon Q: Why is Venus so hot and bright? A: Venus has a very thick atmosphere which traps in the Sun's heat. It is bright because the thick atmosphere also reflects a lot of the Sun's light. This makes it the brightest planet in our solar system. Earth Characteristics Moons: 1
Rings: None

Major Atmospheric Contents: Oxygen, Nitrogen
Life forms: Yes Cool Fact 3 3 24 Q: How does Earth sustain life? A: Well, Earth is a very unique planet. It is at a perfect distance from the Sun to have just the right temperature to support life. Also, it is just the right size and has just the right gravity to sustain life. It would be very hard to find another planet like our Earth. Mars Characteristics 23 3 3 Moons: 2

Life forms: No Cool Fact! Carbon Dioxide Ice! The 4 Outer Planets of our solar system are Jupiter, Saturn, Uranus, and Neptune.
They are extraordinarily bigger then the inner planets and make up 99% of the total mass that orbit the Sun. They are composed of gases and have a liquid heavy metal core. The Outer Planets have a ring around them and are separated from the Inner planets by the asteroid belt. http://www.universetoday.com/33292/the-outer-planets/ Jupiter Characteristics Moons: 66

Life forms: No About the Sun Our sun is also a star, a big ball of gases that we need to survive. Without the sun's energy and heat, there would be no life on Earth. The sun may seem big to us but it is only a small star our galaxy. There has been many stories and cultures based on the Sun. Us humans even made structures and calenders that use the Sun. Stars (Not including the Sun) Constellation About Stars https://www.google.ca/imghp?hl=en&tab=wi http://solarsystem.nasa.gov/planets/profile.cfm?Object=Beyond There are Billions of stars in just our galaxy! There are much more in the universe. They come in many different sizes and colors, from the tiny brown dwarfs to the red and blue super giants. Our Sun is a yellow dwarf star and as i said before is relatively small compared to most stars. Comparison Video http://www.youtube.com/ A Constellation is a group of stars in the night sky that forms a pattern. So far there are 88 Constellations we have divided. http://www.enchantedlearning.com/subjects/astronomy/stars/constellations.shtml Galaxies Formation There are many theories on the formation of galaxies, but currently the best theory would be the Big Bang Theory. It states that after the Big Bang radiation and subatomic particles made the universe. And from then, Galaxies formed. http://science.nasa.gov/astrophysics/focus-areas/what-are-galaxies/ http://www.universetoday.com/16350/what-kind-of-star-is-the-sun/ What is a Galaxy? Well in simple words, a galaxy is many stars, dust, and gases held together by the gravity of all the other stars around it and this "thing" we call Dark Matter. http://www.universetoday.com/30534/what-is-a-galaxy/ Text book Nebula A Nebula (Latin word for "cloud") is a cloud of dust, hydrogen, helium gas, and plasma in space. What is a Nebula? How is it formed? http://www.universetoday.com/61103/what-is-a-nebula/ When a Nebula is born it is called a Nebulae. There are many types of Nebulae, but technically they are formed from the particles dying Stars give off. Cool Fact! Did you know all Stars are made from a Nebula? How about all nebula come from dieing Stars? Meteors, Meteorites Meteor Meteorite Come from meteoroids Shooting star! Burns up when entering Earth's atmosphere. Smaller than Meteorite Does not burn up in Earth's atmosphere Larger than Meteor May leave crater http://curiosity.discovery.com/question/difference-between-meteor-meteorite Comets http://www.edunet.ie/stlaur/whatast.html Asteroid An moving body that orbits the sun made up mainly of dust, ice, and small rocky particles. Comets when getting close to the Sun starts to heat up and vaporize creating its "tail". An moving body that orbits the sun made up mainly of metals and rocky materials. Asteroids orbit closer to the sun for they do not melt like Comets do. Pluto Characteristics Moons: 5
