1. The Solar System

2. Rotation vs. Revolution

3. Comparing the Inner and Outer Solar System
Inner Solar System
Mercury, Venus, Earth, and Mars
Terrestrial planets
Rocky
Solid
Dense
Small diameters
Close to the sun
Few natural moons
Many impact craters
scars on the surface of the planets where they have been hit by objects such as meteors.
Small orbits
Outer Solar System
Jupiter, Saturn, Uranus, Neptune, Pluto*
The Gas Giants
Gas
Less dense
Large diameters
Farther from the Sun
Many natural moons
No impact craters
Large orbits

4. Mercury The Winged Messenger
In Roman mythology Mercury is the god of commerce, travel, and thievery, the Roman counterpart of the Greek god Hermes, the messenger of the Gods.
The planet probably received this name because it moves so quickly across the sky.

5. Mercury Factoids You could fit 287 Mercury’s across the sun
It orbits the sun every 88 days, and completes 1 rotation every 59 days
Mercury has no moon

6. Why does it look so beat up????
It has virtually no atmosphere because it is vaporized from the high surface temperature
No atmosphere lets asteroids bombard surface without being burned up by the atmosphere

7. Venus The Bringer of Peace
Venus (Greek: Aphrodite; Babylonian: Ishtar) is the goddess of love and beauty.
The planet gets this name because it is the brightest of the planets known to the ancients.

8. Venus Factoids Venus could fit across the Sun 115 times
It orbits the sun every 243 days, and completes 1 rotation every 226 days
Venus has no moon

10. The Runaway Greenhouse Effect of Venus
Sunlight passes through the Venusian atmosphere.
The surface of Venus then absorbs the sunlight, which heats it up.
Since the atmosphere on Venus is mostly made up of carbon dioxide, the heat released from the planet get trapped in its lower atmosphere.
This makes the planet and its atmosphere very hot.
The surface temperature is near 900°C, which is hot enough to melt lead.
If there were any oceans on Venus, they have all boiled up and evaporated.

13. Our Moon

18. Mars The Bringer of War Mars (Greek: Ares) is the god of War.
The planet got this name due to its red color (Mars is sometimes referred to as the Red Planet).
The name of the month March derives from Mars.

19. Mars Factoids Mars would span across the Sun 206 times
Mars orbits the Sun every 686 days (1 year and 321 days), and completes one rotation every hours.
Mars has 2 moons

20. Mars Moons
Phobos and Deimos

21. Jupiter
Jupiter (a.k.a. Jove; Greek Zeus) was the King of the Gods, the ruler of Olympus. Zeus was the son of Cronus (Saturn).

Jupiter

23. The basics...
Jupiter takes 12 years to go around the Sun and rotates once every 9.8 hours
To date Jupiter has about 60 known moons!
Jupiter has one very small and faint ring system
The planet is mainly composed of gas and is the largest body in the Solar System next to the Sun.

24. The GRS (Great Red Spot) is a giant storm two times the size of the Earth!
It is the most known storm on Jupiter.
The storm has lasted for over 300 years!
Great Red Spot

25. Saturn The bringer of old age
In Roman mythology, Saturn is the god of agriculture. The associated Greek god, Cronus, was the son of Uranus and Gaia and the father of Zeus (Jupiter). Saturn is the root of the English word "Saturday"
Saturn The bringer of old age

26. General Information Most flattened Planet in the solar system
Rotates once in hours
29 ½ years to orbit the sun
Its density is so small that it would float in water!

27. Saturn’s rings are made up of about 10,000 individual ringlets.
Although they look solid, Saturn's rings are probably less than 50 meters thick and consist of individually orbiting bits of rock covered in ice. These rocks can be anywhere from the size of a grain of sand, to the size of a house.
Saturn's Rings

28. Uranus is the ancient Greek deity of the Heavens, the earliest supreme god.
Uranus was the son and mate of Gaia the father of Cronus (Saturn) and of the Cyclopes and Titans.
Uranus The Magician

29. 27 Uranus’ would fit across the diameter of the Sun
It takes hours to rotate once on its axis and 84 years to go around the sun
Uranus has 27 known moons and a few faint rings

30. What’s weird about Uranus
Uranus is tipped on its side
Thought to be the result of a collision with a planet-sized body, early in the solar system’s formation

31. Neptune The Mystic
In Roman mythology Neptune (Greek: Poseidon) was the God of the Sea.

32. A Few Ditties About Neptune
Rotational Period hours
Revolution Period 165 years
Neptune has 13 known moons and a few faint rings

33. Triton is the largest moon of Neptune, it orbits Neptune in a direction opposite to the planet’s rotation, it is gradually getting closer until it will collide with the planet in about 10 to 100 million years
Triton

34. The Great Dark Spot

35. Pluto
In Roman mythology, Pluto (Greek: Hades) is the god of the underworld.

36. Pluto Info
It takes 248 years to revolve around the Sun and 6 days 10 hours to complete one rotation
Has one moon
