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.
Another name for gaseous planets is Jovian planet meaning Jupiter like.
There are no planets that we know of that are exactly the same size.
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.
the planet is one of the gases planet.. and the dwarf planets are small planets..
A planet with 200 times the mass of Earth is more likely to be a Jovian planet rather than a Terrestrial planet. Jovian planets are typically composed of gases and liquids, while Terrestrial planets are rocky in composition like Earth. The high mass suggests a gas giant planet similar to Jupiter or Saturn.
It is highly unlikely for planets to form on another planet. Planets typically form from material surrounding a star, not from existing planets. However, moons can form around planets through processes such as accretion or capture.

Terrestrial Planets, or Rocky Planets.
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.
A moon? I don't think a planet orbiting another planet would be called a planet.
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.
