2. General Information
• Rotation: when an object spins once on its axis
• Revolve: when a smaller object goes around a larger object once
• There are 8 planets (inner and outer, but not dwarf)
• Mercury, Venus, Earth, and Mars are the inner planets
• Jupiter, Saturn, Uranus, and Neptune are outer planets
• Inner planets are solid spheres of rocks, as they were continuously
hit by the asteroids and meteorites for the first 600 million years
• Outer planets are huge gaseous spheres, and with rings.
• Orbit: the pathway that a planet goes on
• The 3 requirements to be considered as a planet are: 1) it must
have an orbit that goes around the sun, 2) it must have enough
mass to make itself sphere-like because of its gravity, 3) and has
cleared its orbit around the sun
• Dwarf planet: “planets” that met the first two requirements but failed
the third one
• Pluto, Ceres, and Eris are examples of dwarf planets

3. Inner Planets

4. Mercury
• Mercury’s atmosphere is caused by the
short distance from the sun
• Mercury’s atmosphere is consisted of
helium and sodium
• Mercury’s surface was shaped by three
processes: 1) impact cratering, when
large objects from space collided with
Mercury 2) volcanism, where lava had
covered the surface, 3) tectonic
activity, where Mercury’s crust moved in
order to adapt to the planet’s cooling
and contraction.

5. Venus
• Venus is also referred as the “Evening
Star” because it is the brightest planet
that can be seen from earth during
nighttime
• Two elements that can be found in
Venus’s atmosphere are carbon dioxide
and sulfuric acid
• Retrograde rotation is when a planet
rotates clockwise, which is a
characteristic that only Venus have
• Venus rotation takes 243 days, while its
revolution is 225 days
• The sun would appear to rise in the
west and set in the east is because of
its clockwise rotation
• Venus is the hottest planet in the solar
system is because of the ongoing
volcanic activity which had provided the
sulfuric acid for the atmosphere

6. Earth
• The elements that make up Earth’s
atmosphere are nitrogen, oxygen, argon,
water vapor, carbon dioxide, neon,
methane, krypton, helium, xenon,
hydrogen, nitrous oxide, carbon
monoxide, nitrogen dioxide, sulfur
dioxide, and ozone.
• The atmosphere protects us by
absorbing solar radiation before it
reaches Earth, and meteor collision
• Earth’s rotational tilt is 23.5 degrees
• The liquid metallic core of earth causes
the magnetic field on Earth
• The nature occurring satellite of Earth is
the Moon

7. Mars
• Meteorites that hit Mars had
ancient bacteria
• The primary element of Mar’s
atmosphere is carbon dioxide
• Mars appear red because its soil
contained iron-laden clay
• Olympus Mons is one of largest
volcanoes in the solar system:
60 km wide and 26 km high
• Mars’s two satellites are Phobos
and Deimos.

8. Outer Planets

9. Jupiter
• Due to the fast rotation of Jupiter,
the planet’s poles are flattened
and bulge in the equator
• The elements that make up
Jupiter’s atmosphere are
hydrogen, helium, sulfur, and
nitrogen.
• The Giant Red Spot is a hurricane-
like storm
• Jupiter have 50 named satellites
• Jupiter’s satellite, Io, is volcanically
active, and have the highest
temperature than any body in the
solar system (except the sun)

10. Saturn
• Saturn’s atmosphere was made
out of hydrogen and helium
• Astronomers have a theory that
Saturn’s ring is composed of the
particles of natural occurring
satellites that had been broke
down
• The ring is composed of water ice
and dust
• Saturn has a very low density
(lower than any planet in the solar
system) that allows it to flow on
water

11. Uranus
• Uranus’s rotation was different
because of it’s 98 degrees tilt,
so to us it looks like Uranus is
rotating on its side
• Uranus’s atmosphere is made
out of hydrogen, helium, and
methane
• Uranus has 27 known satellites

12. Neptune
• Neptune’s atmosphere is made
out of ammonia, helium, and
methane.
• Neptune has thirteen known
satellites, four are within its ring.
• Triton is Neptune’s biggest
satellite, and astronomer
believed that it wasn’t originally
Neptune’s satellite. Astronomers
believe that Triton became
Neptune’s satellite due to
Neptune’s gravitational pull.

13. Dwarf Planets

14. Pluto
• Pluto’s three moons are
Charon, Nix, and Hydra.
• By using the
spectroscope, scientists
learned that Pluto has
methane frost, and water
frost on Charon.
• Charon was unusual
because of its size; it’s
half the size of Pluto.

15. Ceres
• It takes around 4.6 Earth
years for Ceres’s revolution
around the sun
• Ceres was once considered
as an asteroid because it’s
orbit is within the Asteroid
Belt
• Scientists found a liquid
water layer on Ceres’s
interior

16. Eris
• Before it had Eris as its
official name, Eris was
nicknamed Xena
• It would take 557 Earth
years for Eris to revolve
around the sun
• Eris’s moon is named
Dysnomia
• Eris is not considered to be
a planet because it did not
clear out its orbit
