Our Solar System
Transcript of Our Solar System
at 50 km/sec
Has the biggest iron core
Temperature: 66 degress Celsius
Named after the Roman messenger of the gods (or the Greek god Hermes)
Has the largest temperature range (465 to -184 C) Mercury Venus is similar to Earth in size, mass, density, composition and gravity
Temperature: 461 degress Celsius
Named after the Roman goddess of love (or the Greek goddess Aphrodite)
Venus is the hottest planet in the solar system Inner Solar System Mars Mars is a cold desert world
Looks red because of iron-rich minerals
that go into the atmosphere
Has the largest volcanic mountain - Olympus Mons
Temperature: -63 degress Celsius
Named after the Roman god of war
(Or the Greek god Ares)
There is water on mars
(in ice form) Planet Information Mercury
Neptune 1 year(orbit)= 88 days
165 years 1 day(rotation)= 58.6 days
24 hours,56 minutes
24 hours,37 minutes
19 hours Jupiter Saturn Uranus Outer Solar System A dust/gas cloud floated
in the Milky Way
A supernova exploded
Cloud collapsed & condensed into the sun Surface has light and dark bands of gaseous hydrogen clouds
The Great Red Spot
Atmosphere is similar to the sun
Magnetic field, is about 20,000X stronger than Earth
Temperature: -108 degress Celsius
Named after the king of all the gods (or the Greek god Zeus)
Jupiter is the fastest rotating planet Sizes of the Planets Made of hydrogen and helium.
Largest ring = thickness of 1km
The rings are made of rock and ice particles
Temperature: -139 degress Celsius
Named after the Roman god of agriculture or ( known as Cronus to the Greeks). Uranus is 1 of the 2 ice giants
Methane gas absorbs the red portion of
the light, resulting in a blue-green colour.
Has numerous rings
Named after Uranus, god of the sky.
Temperature: -197 degress Celsius
The angle of its axis is at 98 degrees Powerfull magnetic field
Has the stongest winds - 2,000km/hr
Has 6 known rings.
Temperature: -201 degress Celsius
Named after the Roman god of the sea (or the Greek god Posidon)
Referred to as a twin of Uranus because its about the same size and colour. Pluto (Dwarf Planet)
Demoted as a planet in 2006 because...
It doesn't dominate its neighborhood.
Pluto's orbit is somewhat untidy.
Temperature: -229 degress Celsius
Named after the god of the under world (or the greek God Hades)
Pluto was named by an 11 year old girl in England Our planet! Jupiter Saturn Venus Mars Mercury 4,878km
8. Distance Away
from the Sun
Pluto: 5,916 The only star in our Solar System
Creates star storms from its rotation
Contains 99% of all matter in the Solar System
Temperature: 5,538 degress Celsius
Ancient Romans called it "Sol"
Ancient Greeks called it Helios Has no atmosphere or surface water
Temperatures: 120 to -120 degrees Celsius
Landscape = mountain ranges, craters, plains & ridges.
Surface = layers of rock, dust
The moon's gravity is 1/6 of the Earth's gravity Moons per Planet Mercury
3 Asteroids Earth's Moon The Future of Our Solar System If Astronomers are correct...
Our Solar System should last 5 billion more years!
Guess the order of the planets from largest to smallest! Small celestial objects made of rock and metal A smaller version of an asteroid Large chunks of ice, dust, and rock that orbit the sun Interesting Fact: Saturn has such a low density that it would float in water Big Bang
Theory Solar Nebula
Theory extremely hot
universe cooled, energy
turned into matter
100+ years the matter formed
into the stars and the galaxies Bibliography Nasa. Solar system exploration. Retrieved from http://solarsystem.nasa.gov/index.cfm The only planet with liquid water on its surface and known to support life
The tilt of the axis is 23.5 degrees
Temperature: 15 degress Celsius
"eorthe" in Anglo-Saxon means land
About 70% of Earth is covered in water Meteoriods Asteroid Belt Comets What's Considered a Planet?
Orbits the sun
Large enough to have become round due to the force of its own gravity.
Dominates its orbit Mini Game!! A moon is a celestial object that
orbits around a planet. Dyler, A. (1999) Reader's Digest Pathfinders: Space. Sidney, Austraila: Weldon Owen Inc Barker, Davies, Fazekas, Fraser, LeDrew & Vucic.
