EARTH & SATURN
Differences (Earth)
 Earth’s name meaning is ground.



Earth is the third planet from the
sun. Earth orbit the sun with the
average distance of 150 million km
23 hours, 56 minutes and 04
seconds (24 hours) to spin around
once.
Earth’s mass is
5,972,190,000,000,000,000,000,00
0 kilograms. The diameter of Earth
is 12.756 km.
The gravity on the Earth’s equator is 9.789
m/s2. But the gravity on the poles is 9.832
m/s2.
Similarities
 Named after the Roman
gods and goddess
 It orbits the sun normally.
Not like Pluto.

Differences (Saturn)
 Saturn’s name meaning is Agriculture.

Saturn is the sixth planet from the sun. Saturn orbits
the Sun at average distance of 1.43 billion km

Saturn took 10 ¼ Earth hours to spin around once.

Earth and Saturn is not a
dwarf planet.

Saturn’s mass is
568,319,000,000,000,000,000,000,000 kilograms. The
diameter of Saturn is 108,728 km.

Both of the planets
have gravity that can
make us stand on the
planet. We’re not
floating.

The gravity on Saturn’s equator is 10.4 m/s2 .

It took a year to orbit the sun
(365.25), Earth revolves around the
Sun at the speed of about 18.5
miles/sec (30 km/sec).


Saturn orbits around the sun once every 29.4 Earth
years. Saturn travels at an average speed of 21,637
miles per hour /34,821 kilometers per hour in its orbit
around the sun.

Earth’s temperature is about 15°C.
The coldest temperature is around
−89.2 °C and the hottest
temperature is around 57.8 °C


Saturn's
temperature is about -270 degrees Fahrenheit or -168
degrees Celsius.

Earth is a terrestrial planet. It has
inner core, outer core, mantle and

Saturn is a gas giant planet. It is mostly compost of
hydrogen and helium.
crust.





Earth only has 1 moon. Moon is the
fifth largest satellites in the solar
system. Its temperature is around 53.15°C.
Earth have no rings


Saturn has
around 62 moons. The biggest in Titan and the second
largest moon is Rhea.


The large
rings are made of thousands of smaller rings. The
pieces in the rings are not spinning off into space
because it’s pulled by Saturn’s gravity. The rings are
wide but not very thick.
On Earth, everything is just perfect.
It has oxygen in the Earth’s
atmosphere. Our gravity is also not
more, not less. We’re not crushed
and we’re also not floating in the
air.
Earth was originally born as a twin
to the planet Theia, which was
about half of Earth, about the size
of Mars. The two planets shared an
orbit for several million years until
they collided (crash). Earth
absorbed Theia, and the remaining
debris eventually coagulated into
Earth’s moon. The mass
donated/given by Theia gave Earth
the gravity
Before, people believed that Earth
is the center of the Solar System.
This belief was pushed by Claudius
Ptolemaeus, also known as
Ptolemy. Ptolemy believed that the

We would
just weight a little more in Saturn. If you weigh 100
pounds on Earth, you would weight 115 on Saturn.


Storms on Saturn can last of months or even years. A
long-lived 2004 storm on Saturn, named the “Dragon
Storm,” created mega-lightning 1,000 times more
powerful than lightning on Earth
Saturn is sometimes called “The Jewel of the Solar
System.”
Saturn is the only planet that could float in water.
A day on Saturn is 10 hours and 14 minutes.
The day Saturday is named after Saturn

On July 1, 2004, the Cassini-Huygens was the first
spacecraft to orbit Saturn. Launched on October 15,
1997, It traveled over 2,000,000,000 miles at a speed
of 70,700 miles per hour before it reached the ringed
planet. Its mission has been extended to 2012.
stars and the other planets orbited
the Earth.
Why Earth is the only planet that
support live?
Why only some of the planets have
rings? Why Earth doesn’t have
rings?
Why terrestrial planet is placed on
the inner of the asteroid belt?

What if
Saturn has 2 rings not just 1?

If Saturn is
the first planet from the sun, will it sometimes block
the other planet to get the sunlight?
Why gas

belt?
Conclusion:
Earth is the places where it can support live. No other creatures have been discovered in other planets (yet). Earth has the right atmosphere,
gravity, temperature and others. The atmosphere gave us oxygen. The gravity is not too little that it could make us float or even too much
gravity. The temperature is also not too hot and not too cold. Earth also has day and night and also seasons that could help human or even other
living things.
