Period 7th

2. Mercury (My)
• Mercury is the 1st planet to the sun also
the hottest. Mercury is the smallest of the
eight planets but slightly bigger the Earth’s
moon. One day on Mercury is 59 Earth
days because Mercury’s orbit around the
sun is shorter because it is closest to the
Sun. Mercury is a rocky planet, other wise
known as a terrestrial planet. Mercury has
a solid, cratered surface, like Earth's
moon. Mercury's thin atmosphere, is
composed mostly of oxygen, sodium,
hydrogen, helium, and potassium. Atoms

3. Venus (very)
• Venus is the 2nd planet to the sun and the
brightest. Venus in most cases is called
Earth’s twin because they very in
similarities. One day on Venus lasts as
long as 243 Earth days. Venus is apart of
the rocky planets also known as
terrestrials, its surface is a cratered and
volcanic landscape with an atmosphere
made mostly up of carbon dioxide and
nitrogen, with clouds of sulfuric acid

4. Earth (excellent)
• Earth is the 3rd planet from the Sun and
the only planet that we know of that
supports life and liquid water. Earth makes
a complete orbit around the sun a year in
Earth time in about 365 days, a day on
Earth is when it has completed a rotate on
its axis. The Earth's atmosphere is made
up of 78 percent nitrogen , 21 percent
oxygen and 1 percent other ingredients
which makes the perfect balance for us to

5. Mars (Mother)
• Mars is the fourth planet from the sun at a
distance of about 228 million km, 142
million miles. Mars makes a complete orbit
around the sun in 687 Earth days. Mars’
has a surface that has been altered by
volcanoes, impacts, crustal movement,
and atmospheric effects such as dust
storms. Mars has a thin atmosphere made
up of carbon dioxide, nitrogen and argon .
About 40 spacecraft's have been to or
orbited Mars and its surface the first
mission made a success was Mariner 4 in

6. Jupiter (Just)
Jupiter is the fifth planet from the sun at a
distance of about 778 million km which is
484 million miles. Jupiter makes a complete
orbit around the sun in about 12 Earth years,
4,333 Earth days. Jupiter is a gas planet
which means it has no solid surface but has
a core. Jupiter's atmosphere is made up
mostly of hydrogen and helium. Jupiter's
Great Red Spot is a gigantic storm about the
size of two to three Earths that has been

7. Saturn (Served)
Saturn is the 6th planet that orbits the Sun. Saturn makes a
complete orbit around the sun a year in in 29 Earth years.
Saturn is a gas-giant planet and does not have a solid surface
its
atmosphere is made up mostly of hydrogen and helium.
Saturn has 53 known moons.
Saturn has the most spectacular rings of all our solar system's
planets. It is made up of seven rings with several gaps and
divisions between them. Five missions have been sent to
Saturn. Since 2004, Cassini has been exploring Saturn, its
moons and rings. Saturn cannot support life as we know it.
However, some of Saturn's moons have conditions that might
support life. When Galileo Galilei looked at Saturn through a
telescope in the 1600s, he noticed strange objects on each side
of the planet and drew in his notes a triple-bodied planet system

8. Uranus( Us)
Uranus is a gas giant and therefore does not have
a solid surface. Uranus is made up of a hot dense
fluid of "icy" materials, methane, and ammonia ,
above a small rocky core. Uranus has an
atmosphere which is mostly made up of hydrogen
and helium, with a small amount of methane
.Uranus has 27 moons. Uranus' moons are named
after characters from the works of William
Shakespeare and Alexander Pope. Uranus has
faint rings. The inner rings are narrow and dark and
the outer rings are brightly colored. Voyager 2 is the
only spacecraft to have visited Uranus. Uranus
cannot support life as we know it. Like Venus,

9. Neptune (Noodles)
Neptune does not have a solid surface. Neptune is mostly
made of a very thick, very hot combination of water,
ammonia, and methane, heavier, approximately Earthsized, solid core. Neptune's atmosphere is made up of
mostly hydrogen, helium and methane. Neptune has 13
moons. Neptune's moons are named after various sea
gods in Greek mythology. Neptune has six rings.

11. ~Fun Facts~
• On Jupiter my weight would be 225.762 and on Mars my weight
would be 36.004 (Current Weight on Earth 95.5)
• It is impossible to snore while sleeping in the weightlessness of
space.
• About 99.86 percent of the mass of the Solar System is made up
of the Sun.
• It takes about 1.25 seconds for moonlight to reach the Earth
whereas sunlight reaches earth in 8 minutes 19 seconds, so you
can judge how close moon is to us & how far sun is from earth .
• There is no water or atmosphere on Mercury.
• Saturn has such a low density that it would float if put in water.

12. STAR PROMPTS
1.Classify the planets into two categories and tell me how each planet fit the criterion.
The Inner planets are the planets that have a solid surface able to land on and are to the
left of the asteroid belt.
The Outer Planets are the gaseous planets that have and iron core, rings, and mainly made
of gases also are to the right of the asteroid belt.
2.Distinguish the difference between rotation and revolution.
The difference between a rotation from a revolution is that a rotation is just the planet
spinning on its axis, and a revolution is when the planet has made its trip all the way
around the Sun and is starting what we call a new year.
