Introduction
• Our solar system formed from a swirling
cloud of gas and dust.
• The sun -made from the densest matter
that became very hot and started to
produce its energy by nuclear fusion.
Introduction
• The remaining matter continued swirling
around the sun because of the sun’s
gravity and eventually clumped together to
make solid forms =planets, moon, and
other objects of space.
The Planets
• In order from the sunMercury; Venus; Earth; Mars (inner)
Jupiter; Saturn; Uranus; Neptune (outer)
The Planets Mnemonic Device

INNER PLANETS
• Mercury, Venus, Earth
and Mars.
• Terrestrial means
“Earth-like”
• All have rocky surfaces
like Earth.
MERCURY
• Closest to the Sun.
• Thin to no atmosphere
• “planet of extremes”
• temps range: -170C to
425C
• No moons
VENUS
•

•
•
Earth’s twin
Greenhouse effect
“Evening star”
Retrograde rotationspins East to West
• Carbon dioxide; thick
atmosphere
• No moons
EARTH
• 70% water
• Atmosphere -mostly
Nitrogen
• Rotates West to East
• 1 moon
• 3rd from the sun
MARS
• “Red Planet”
• Ice Caps
• Thin atmosphere mostly Carbon Dioxide
• 2 moons- Phobos,
Deimos
• Axis is tilted & has
seasons like Earth.
OUTER PLANETS
• Jupiter, Saturn, Uranus,
and Neptune.
• “Gas giants”
• All have gaseous
atmospheres/surfaces.
• Have rings. Some rings
are more visible than
others.
JUPITER
• Largest of all planets
• Has a “Great Red Spot”storm of swirling highpressure gas
• Faint rings.
• 4 well-known moons- Io,
Callisto, Ganymede,
Europa
SATURN
• visible rings made of
ice, dust, and rock.
• 2nd largest planet
• Less dense than water
(would float in water)
• Largest moon (Titan)- is
bigger than Mercury
URANUS
• Methane Atmosphere
• Bluish in color
• Rotates from top to
bottom (like a tire)
• Faint rings that
surround the planet
vertically (up and down)
NEPTUNE
• Atmosphere has very
visible clouds.
• Has a “great dark spot”
• Has Faint rings
• Last planet
• 8th from the sun
