Solar System
Prepared by Suvastigan
Planet’s
1. Mercury : mercury is planet that don’t
have any moon. Mercury is the
closest planet to the sun. Mercury is
the smallest planet in the solar
system. When mercury is facing up to
the sun it will be so hot, almost the
heat as the sun. When mercury is
facing the other side , it will be
freezing cold. Mercury is a un
habitable planet which doesn’t have
life.
2. Venus: Venus is also a planet that
doesn’t have any moon. Venus is the
second closest planet to the sun.
Venus is the third smallest planet in
the solar system. Venus is the same
size as earth. Venus is un habitable
planet. 1billion to 3billion years ago
Venus had liquid water on its surface
and many life roamed that planet.
Suddenly Venus get closer to the sun
the waters stared to evaporate, many
lives had died because of the heat
3. Earth: Earth is our planet or our
home. Earth has one moon called
‘Moon’. Earth is the third closest
planet to the sun. Earth is the fourth
largest planet in the solar system.
Earth is a habitable planet well its
obvious. We are the most complex
species in the Earth. Because we are
intelligent, we can think what is good
and what is bad, we can make thing
better and we can create something,
that’s why we are the most complex
species in the planet Earth. Earth is
habitable because it is in habitable –
zone.
4. Mars: Mars is a planet that does have
moons called Phobos and Deimos.
They’re shape almost look like a giant
potato. Mars is a red and dusty
planet. On Mars there’s a volcano
called Olympus Mons’. Olympus
Mons is three times taller than
Mountain Everest. Like Venus,
2billion to 4 billion years ago, Mars
had liquid water on it’s surface and
creature roamed that planet. Now,
N.A.S.A has develop a rover called
Curiosity Rover. They create that
rover to discover new life forms. One
day, N.A.SA has discovered bacteria.
Mars is in habitable-zone.
5. Jupiter : Jupiter is a gas giant. Jupiter
has 79 moons. The most common
ones are Io, Europa, Ganymede and
Callisto and there are known as
galilean moons because it was
discovered by a astronomer called
Galileo Galilei. The biggest of all
gelilean moon is Ganymede. Jupiter is
made of helium and hydrogen.
Jupiter is the biggest planet in the
solar system. Jupiter has a spot called
‘The Great Red Spot’ that isn’t always
red. Sometimes, its will be white.
Jupiter is a un-habitable planet.
Jupiter doesn’t have surface
6. Saturn: Saturn is also a gas giant
same. Saturn is made of hydrogen
and helium like Jupiter. Saturn has 82
moons. Well that’s a lot. Saturn has 3
rings that made of very small ice.
Saturn was discovered by astronomer
Galileo Galilei. Saturn is a un
habitable planet. Now N.A.S.A is
trying to get rover to the surface. But
suddenly they said that Saturn
doesn’t have a surface. Many years
ago, Saturn was named Saturnus
named after the Greece.
7. Uranus: Uranus is ice giant but it’s not
fully made out of ice and there are
many gases in Uranus. Uranus has a
surface but not like earth. It’s a small
rocky core. But N.A.S.A didn’t sent a
rover because of the pressure and
cold. Uranus is the coldest place in
the solar system. Uranus has 27
moon’s. Like Earth in the north part of
Uranus they’re a ‘aurora’ swirling
across. But not only Earth and Uranus
has this ‘aurora’ phenomena. Jupiter,
Saturn and even Neptune have it.
Neptune has a faint ring is less than 2
km.
8. Neptune: Like Uranus Neptune is a ice
giant. Neptune has 14 moons. Like
Jupiter Neptune also has a spot called
‘The Great Dark Spot. Neptune also
have a faint ring. Neptune and
Uranus are like twins. Because
they’re made out of same material,
they have same ring and other. But
the only two is different, the mass
and size.
Dwarf planet
What is Dwarf planet?
Well, it’s kind a look’s like a planet but it is much
smaller and low in mass
Pluto: Pluto is a dwarf planet. It has a moon
called Charon. It is half size of its bigger one,
Pluto. When N.A.S.A discovered Pluto it was
consider as the last planet of the solar system.
But it’s wrong, they have discovered more dwarf
planet like Eris and Haumea and more.
Comet
What is a comet?
Like asteroid, comet is a space rock but it’s made
out ice. When comet is moving it is so fast.
Comet has a tail made out of ice.
Star
1. Sun: Sun is our star. It is so hot that it can
melt a lead. Sun uses its hydrogen to light
up. The sun’s gravity is to hold its own
planet. In 6 billion years the sun will use all
of it’s hydrogen and will burn lower. The
sun will started to get bigger and bigger
until it’s a red giant and planet will get
hotter and hotter until the sun swallow it.
Eventually the sun will cool down become
a white dwarf and the it will be cooling and
cooling and become a black dwarf. This will
make human’s to extinct.
Star’s:
(Closest to the sun)
1. Betelgeuse
2. Proxima Centauri
3. Sirius A
4. Rigel
5. Alpha Centauri
Core.
What is core?
It’s a layer of hot rock and lava. Every star, planet,
dwarf planet, even moon has core.
Sun:
Mercury:
Venus:
Earth:
Mars:
Jupiter:
Saturn:
Uranus:
Neptune:
Pluto:
Average normal asteroid:
What is Earth’s
Electromagnetic Field?
Electromagnetic Field or (EMF) protect us from sun’s
high amount of radiation. It is form by earth’s moving
core. It stretches from north to south with many
layer’s. This (EMF) is not only in earth. It’s in mars,
jupiter and the ice giant’s.
What is habitable zone and
un habitable zone.
Habitable Zone: The planet’s that are in habitable zone
may contain life because it is not close to the sun and
not too far from the sun.
Un Habitable Zone: The planet’s that are in un
habitable zone may not contain life because it is
closed to sun or far from sun.
Earth is in habitable zone!
Belt’s and cloud
Belt: There’s a belt called Asteroid Belt and Kuiper
Belt. Asteroid Belt is made out of asteroid and ice. It is
between mars and jupiter. Kuiper Belt is right behind
neptune. It is also made out of asteroid and ice.
Cloud: There’s a cloud called Oort Cloud. It is far
beyond the Kuiper belt. It is the end of solar system. It
is so far it will take almost 3 decades. It is also made
out of asteroids and ice.
