Neptune was discovered in 1846 through observations of Uranus. Uranus' orbit was seen to appear to alter slightly through the gravitational effect of another planet, which turned out to be Neptune.

Before Neptune was discovered, irregularities in Uranus's orbit led to its prediction. Verrier was actually able to predict where Neptune was and was within one degree accuracy.

Another name for gaseous planets is Jovian planet meaning Jupiter like.
What makes a moon a moon is the fact that it is smaller than the object it is orbiting, and is orbiting the object (the planet) constantly.The definition of a moon is "a natural satellite revolving around a planet". Since a satellite is an object that orbits a bigger object, usually a planet, and is not a planet due to its small size, it is considered a moon and not another planet.
There are no planets that we know of that are exactly the same size.
the planet is one of the gases planet.. and the dwarf planets are small planets..
Dwarf planets are not a special type of planet. A small planet is later classified a dwarf planet. The only characteristic that makes it a dwarf planet is the size. Your question should be why are some planets small?
No, it might form from another planet but definitely not on another planet.
Terrestrial Planets, or Rocky Planets.

Terrestrial planet is another way of saying rocky planet. The inner rocky planets are; Mercury, Venus, Earth and Mars.
A moon is an object that orbits a planet. A planet cannot orbit another planet.
All planets are affected by the gravity of other planets.
Maybe.....on Mars but not other planets
It means between planets, or from one planet to another.
There are lot's of planets out there, 7 in our solar system alone. :P

Two planets orbiting each other. The barycenter of the planets must not lie within either planet but must be in free space between them. (The planets orbit a central point as opposed to a planet-sattelite configuration where one body orbits another)
NO. All the planets are in (more or less) fixed orbits.
