THE SOLAR SYSTEM
By: Hannah
THE SUN
The Sun is our star without it we
wouldn’t be living right now.
We cant go on or near the sun
its too hot, even if we could go
on the sun it would be
impossible to move because of
all the gravity. The sun has
99.86% mass in the Solar
System.
MERCURY
Every Seven years Mercury can be
seen from earth (the next time this
will happen is May 9 2016).Mercury
is named after Roman god
messenger. A year on Mercury is 88
days and a Mercury day is 176 Earth
days. Mercury has no moons or
rings because it has not a lot of
atmosphere
VENUS
Venus is named after roman
goddess love and beauty. Venus
is sometimes called Earths
sister planet because there
mass and size is so similar.
Venus is the hottest planet in
the solar system with a
temperature of 462 Celsius or
863 Fahrenheit.
EARTH
Earth was formed about 4.54
billion years ago and so far is
the only planet to have life on
it. A year on earth lasts a little
over 365 days it is actually ¼
of a day over 365 days this is
why we have a leap year.
MARS
Mars is named after the Roman
God of war. Mars has the
largest dust storms in the solar
system. It takes Mars 687 Earth
days to orbit the sun with its
radius of 227,840,000 km.
JUPITER
Jupiter is named after the Roman king
of the Gods. It would take 11 earths
lined up next to each other to get
from one side of Jupiter to the other,
it would also take 317 earths to equal
Jupiter's mass. Jupiter's red spot is a
gigantic storm that has been there for
over 300 years! If Jupiter had 80 times
more massive Jupiter would have been
a star instead of a planet
SATURN
In Roman mythology Saturn was the
father of Jupiter, this relationship
makes sense because Jupiter and
Saturn are similar in many ways.
Saturn is nicknamed the ringed
planet because of its beautiful rings
which are mostly made from chunks
of ice. Saturn is also known as a gas
giant but scientists believe it has a
solid rocky core.
URANUS
It takes Uranus 84 earth days
to orbit the sun. Uranus is
sometimes referred to the ice
giant because its helium and
hydrogen on its upper layer.
Uranus winds can reach up to
900 km per hour this is about
560 miles per hour.
NEPTUNE
It takes Neptune 165 earth days to
orbit the sun. Neptune is the
Roman god of the sea, in Greek its
name is Poseidon. The largest
Neptune moon is Triton, Triton was
discovered just 17 days after
Neptune itself was discovered
which was September 23, 1846.
THE SOLAR SYSTEM
The solar system is made up of
the sun, eight planets, seven
dwarf planets, 146 moons,
millions of comets, asteroids,
ice, and space rocks.
THE MILKY WAY
The milky way began forming
around 12 Billion years ago. The
milky way was created by a merging
of smaller galaxy's through time.
The Milky way is made up of at
least 100 billion stars, dust and gas.
It takes the milky way 200 million
years to rotate and it takes light
100,000 years to cross the milky way
OUR MOON
Scientists believe the moon was
created 4 ½ billion years ago, the
moon was created when a large
object hit the earth and blasted
out rocks they eventually melted
together and became the moon.
STARS
There are about 400 billion stars
in the galaxy. Stars are made of
dust clouds all around space. Stars
actually don’t twinkle they are
actually blinking. The north star
isn't one star its several stars
orbiting each other.
IF A BLACK HOLE
ENTERED THE SOLAR
SYSTEM
Well first a black hole is formed after
a stars death and nothing can escape
it.If a Black hole entered we wouldn’t
be able to see the black hole but we
would get to see our planets being
ripped apart if the planet was in its
path, when the black hole gets closer
to earth volcanos and earthquakes
would be huge. long story short we
would all die
