Big Bang Theory
What is the Big Bang Theory?
An explanation of what happened at the beginning of our
universe.
When did this all take place?
About 15 billion years ago our universe sprang into creation.
The Bang
A huge explosion happened that expanded the universe. All the
matter and energy were contained at one point.
Was it a REAL explosion?
It was a not an explosion like a bomb, matter of fact it was
explosion of space within itself.
4. Outer Four Planets
Jupiter
Astroversity.blogspot.com
The largest planet.
Outer atmosphere is very cold, but inside the planet it gets hotter and hotter
towards the core.
Takes 12 Earth years to get around the sun.
Has rings around it, and a gravitational pull 10,000 times stronger than the Earth.
Saturn
Second largest planet in our solar system. Almost 10 times larger than Earth.
Takes almost 30 Earth years to get around the sun.
From a distant looks yellowish, but is really pale yellow, golden brown, and
reddish brown.
Has 22 moons. Titan is one of them, which is one of the largest in the solar
system.
5. Outer Four Planets
Uranus
Third biggest planet, 4 times bugger than the Earth. Astroversity.blogspot.com
Only discovered about 200 years ago.
It is fuzzy and blue.
Tipped over, so it looks like it’s rotating completely on it’s side. Takes almost 42
Earth years.
15 moons
Neptune
A little smaller than Uranus.
Farthest away from the sun.
Takes 165 Earth years to get around the sun.
Has 2 rings that circle it.
Has 3 satellites.
6. Inner Planets
Mercury
Astroversity.blogspot.com
The closest planet to the sun.
The smallest known planet.
Weak magnetic field around mercury, and the atmosphere is much thinner than
the Earths.
Moves around the sun much faster than the Earth.
Days are terribly hot and the nights are terribly cold.
Venus
A little smaller than the Earth.
Closest planet to the Earth.
Takes more than half a year to turn on it’s axis.
Clouds swirl around fast, 250 miles an hour, faster than ANY hurricane.
Very HIGH temperatures day and night.
7. Inner Planets
Earth Astroversity.blogspot.com
The third plane from the sun.
Covered with 3 times more water than land.
Has a magnetic field all around it.
Takes 24 hours to make one rotation.
Life is possible almost anywhere.
Natural satellite is the moon.
Mars
Farthest inner planet from the sun.
It is a bit more colder on Earth, but it has volcanoes, lava fields, and canyons.
Atmosphere is much thinner than Earth’s, and fully of carbon monoxide.
Has seasons.
Has 2 satellites.

How old is the moon? www.sos.noaa.gov

The Earth and moon formed at the same time. Earth was formed by big
chunks and icy material, and then a big piece knocked into the Earth and
knocked a big piece loose and that became the Earth.
