Our Solar System•Composed of 8 planets, their moons, various comets, asteroids & other objects that revolve around a star•A planet is a large space object that moves in a curved path around a star.•The solar system contains large clouds of dust and gas.
The study of the universe or outer space is called Astronomy.
Asteroids•Large pieces of space rock with irregular shapes•??Left over material from the formation of the solar system•Most are found in the asteroid belt between Mars & Jupiter.•They can collide with objects creating huge craters.

Comets•Space bodies made up of ice, dust and small, gritty particles (dirty snowballs)•The ice turns to gas, producing a streak called the tail.•The comet’s tail always points away from the Sun.•Most comets come from the Oort cloud, which is located at the outer edge of our solar system.

http://youtu.be/rsTE6pV4wpUWhat are Comets? 3 min.
Meteoroids•Pieces of rock or dust that are smaller than asteroids•When entering the Earth’s atmosphere, they usually burn up & produce streaks of light – meteors – shooting stars.•Those that land on the Earth’s surface are called meteorites.
•In space – meteoroids – with the asteroids•In our atmosphere – meteors – burning up•On the land – meteorites – all right

Rotation•The movement of a space object turning on its axis.
Period of rotation – the amount of time it takes for an object to rotate once
Revolution•The movement of a body in space around another body•Orbit – the path of a body in space revolving around another body
Mercury•Inner planet•Closest to the Sun•Terrestrial – solid & rocky•Smallest planet•Slow rotation•Fast revolution•No water•Thin atmosphere•No moons
God of Speed
1
Venus•Inner planet•Terrestrial•Hottest planet•Earth’s twin (about the same size)•No moon•Thick atmosphere (CO²) traps the heat from the Sun
Goddess of Love
2
Earth•Inner planet•Terrestrial•3rd rock from the Sun•Only planet that supports life•75% covered with water 3
Goddess of Earth – Terra Mater
Mars•Inner planet•Terrestrial•Thin atmosphere•“Red Planet” – due to the red soil & rocks (iron oxide)•Largest volcano in the solar system – Olympus Mons•2 moons – Phobos & Deimos•Most studied planet (besides Earth) in the solar system
God of War
4
Asteroid Belt•Found between the orbits of Mars and Jupiter
Jupiter•Outer planet – Gas Giants•Largest planet•Mostly hydrogen & helium•Does not have solid surface•Rotates very fast•Thin set of rings •66 moons•Large red spot – huge storm
God of Sky & Thunder
5
Saturn•Outer planet – gas giant•2nd largest planet•Largest system of rings•62 moons – Titan (largest)•Jewel of the Solar System
Roman God for Farming
6
Uranus•Outer planet – Gas Giant•Very cold•Tipped over on its side•Has rings and many moons•Retrograde rotation
God of the Sky
7
Neptune•Outer planet – Gas Giant•Most distant from the Sun•165 years for one revolution around the Sun•Has rings and many moons •Triton, largest moon, revolves backward/retrograde
God of the water and sea
8
Pluto•Dwarf planet•Half the size of Mercury•Made of ice and rock•Thin atmosphere•4 moons
God of the Underworld
