The document summarizes information about the planets in our solar system. It describes each planet's name origins from Greek and Roman mythology and gods. For example, Mercury is named after the messenger of the Roman gods. It also provides some key facts about each planet, such as Venus having a dense atmosphere, Earth's tilt causing seasons, and Jupiter being the largest planet. The summary concludes by explaining that Pluto is no longer classified as a planet since 2006 due to its small size and orbit within the Kuiper belt.

1. THE SOLAR SYSTEM
THE PLANETS

2. PLANET
• From the Greek PLANETAI means wandering or roaming, moving with no goal.
• In roman time STELLAE ERRANTES, an errant star, a body moving with no goal in no predetermines
fashion.

3. THE SUN
APOLLO, GOD OF THE SUN
• patron god of musicians and poets, he carries a lyre and his symbol represents the “egg of creation.”
• The sun is hot, really hot, up to 5,800Kelvin (5600 Centigrade) due to the nuclear reactions in is core.
• The sunlight supplies the body with about 90 percent of its Vitamin D

4. MERCURY,
MESSENGER OF THE ROMAN GODS
(FIRST PLANET FROM THE SUN).
• related to the Latin word merx, which means merchandise, mercari,
or trade, and merces, or wages. He is therefore the god of Commerce and Trade
• Mercury’s spin is slow; so slow that six Earth months go by before the Sun appears from one high noon
to the next high noon.

5. VENUS
GODDESS OF LOVE AND BEAUTY,
SPRINGTIME AND FLOWERS
• The planet is so named probably because it is the brightest of the planets observed by the Greeks and
Romans.
• Also known as the morning star or evening star depending on which side of the sun it is placed
• The atmosphere is so dense we could nearly swim through it

6. EARTH
GAIA, CALLED TERRA MATER (EARTH MOTHER) BY THE ROMANS
• The Greeks had a theory that the earth was the center of the universe and that the moon and the sun
were in fact spinning around her.
• The hearth orbit follows a perfect ellipse around the sun
• If her orbit changed and carried her closer to the Sun, she would roast, and life as it now exists would
be destroyed.
• Too far away from the Sun, she would freeze into a ball of ice.
• Earth’s tilt causes the seasons.

7. MARS
THE RED PLANET, WAR PLANET
• Mars was the Roman war god; his shield and spear form the planet’s
symbol
• It is used now as the symbol for man
• The race to Mars should see the first man around 2029 according to Elon Musk CEO of space X.

8. JUPITER
THE KING OF KINGS
• Jupiter (Iuppiter, Juppiter, and/or Jove) was the ancient Italian Father or Lord of Heaven and provider of
fertilizing rains
• Jupiter as the biggest moon Ganymede measuring 5,276 kilometers in diameter

9. SATURN
GOD OF HARVEST
• Saturn has more than twenty satellites. The biggest is Titan,
• The rings of Saturn were first seen by Galileo in 1610
• Saturn's rings are made up of billions of particles ranging from grains of sand to mountain-size chunks.
• Composed predominantly of water-ice, the rings also draw in rocky meteoroids as they travel through
space.

10. URANUS
GOD OF THE SKY
• From Orsano the rain Maker, coming from the sky, above us
• The first planet discovered in “modern” times (1781)
• Name George at first in honor of King George, then given a more mythical name in accordance to the
rest of the planets
• It’s spinning sideways, the poles are at the equator

11. NEPTUNE
GOD OF THE SEA
• Neptune, or in Greek mythology, Poseidon, is one of the twelve gods of Olympus.
• By observing Uranus's orbit, scientists discovered an anomaly, another planet’s gravity was at play
• The planet is about seventeen times more massive than Earth. Astronomers now regard Neptune and
Uranus as twin planets, somewhat alike in size, density, mass, and rotation.

12. PLUTO
• A planet that’s not a planet
1. The object must orbit the Sun.
2. The object's gravitational pull must be strong enough that it pulls the object into a spherical shape.
3. The object must be massive enough to clear its orbit of debris.
• Pluto does not qualify for those criteria
