If we're live in the same solar system, but in the different planet, and your planet orbiting our star 2 times more faster than my planet...?

The "number of planets" is a number that has changed many times in the history of astronomy. And that is usually because the meaning of the word "planet" keeps changing. Words, as we use them today in astronomy, started with Greek culture (a little over 2000 years ago).

At the time, anything in the sky was called an "aster" (? in the Greek alphabet), a word that gave us the English words "star", asterisk (* it has the shape of a star) and asteroid. Things that were high in the atmosphere (but not in space) were called meteors. Clouds are meteor, so are raindrops and snowflakes.

That is why the study of these things is called meteorology. In astronomy, we use the word meteor for the trail of light left when an object enters the atmosphere at great speed (a shooting star). Everything in space was called an "aster".

Most were fixed objects. However, some bright ones moved in a way that was (eventually) predictable. Each one was called "aster planetes" (? = star that moves).

Others were unpredictable and looked as if they had a head of hair (aster cometes = star with hair), and we know them as "comets". The Greek (and older civilizations) knew of seven objects they called "aster planetes": Sun (Helios), Moon (Selene), Mercury (Hermes), Venus (Aphrodite), Mars (Ares), Jupiter (Zeus) and Saturn (Chronos). Rome was founded by exiled Greek soldiers who were not up on astronomy, so for a while, they thought the morning apparition of Venus was a different planet, and they called it Lucifer (the bringer of light -- since it rises just before the Sun), but astronomers already knew it was just Venus.

Things stayed that way until 1610, when Galileo turned a telescope to the sky and found four objects around Jupiter. Since they met all the requirements (back then) for an "aster planetes", he called them planets. Suddenly, we jump to 11 planets.

In the following years, a few more "planets" were discovered (for example, Titan, around Saturn), but astronomers became reluctant to use the word planet for these objects. If they had continued to use the word planet under its old definition, the list would include 17 planets by 1686: Sun, Moon, Mercury, Venus, Mars, Jupiter, Io, Europa, Ganymede, Callisto, Saturn, Titan, Iapetus, Rhea, Tethys, Dione, Uranus. However, astronomers never used the word "planet" for the other satellites of Saturn (after Titan) so we can say the list of planets topped up at 13, around 1660.

Newton proved (around 1686) that the system of planets revolved around the Sun, not the Earth. This was the first major "redefinition" of the word planet (and also of other words, like star). The Sun lost its status as a planet, and got upgraded to a "star" The Moon lost its status as a planet, and got "downgraded" to a satellite, just like the 4 around Jupiter and the 5 around Saturn.

Uranus was confirmed as a planet. Earth lost its status as "centre of the universe" and got downgraded to planet. We now have (in 1686) 7 planets and 10 satellites.

Ah, well ye see it is like this laddy; astronomers decided(who gave them that right, I don't know) but, they decided because of its small size (what if it were bigger?) and queer orbital track around the sun(which is a star).....anyways because it had such a large orbit it takes 248 years to make one rotation around the sun. Because it is smaller than the moon of Neptune, well it is called a dwarf planet. Yet the dwarf has 2 moons revolving around it.

I guess word got out that the "Plutonians were thinking this planet is all wet (the only one) that has only 1 moon that thinks it is Better than Pluto so it is called a dwarf PLANET. Hell at that rate you can call Mercury the same dwarf planet as it has no moons and is HOT, HOT, HOT But take into account that "Sumerians had knowledge 6000 years ago" so way before telescopes, and they knew of Uranus and Neptune as well. Science aught to think about that.

Because that knowledge has been passed down through the various civilizations up until we actually had telescopes that could see that far in 1930 http://www.abovetopsecret.com/forum/thread332560/pg1.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
