Current detection methods are only capable of detecting planets which are close to their parent star. This may not be a trend, only statistically biased.
The reason that most extrasolar planets are found close to their parent stars is that the amount and frequency of the star's motion are both higher in these planets.
the amount and frequency of the star's motion are both higher.
You can find the names of some 260 different stars with planets circling them here: http://exoplanet.eu/
Of what we have found most are the size of Jupiter or larger. But we know many more extrasolar planets exist that we simply cannot detect. If we were to draw hypotheses on what planets are most abundant they would either be similar to dwarf planets. Or, if the reader does not view dwarf planets as true planets then planets the size of ones in the terrestrial zone like: Mercury, Venus, or Earth. Are probably the most abundant.
They are found in Space close to there planets

Extrasolar planets are planets found orbiting stars other then our own.
There are 464 extrasolar planets, and 8 planets within our Solar System. This makes a total of 470 known planets.

Maybe it's because they have to be extra large to be discovered.
The current planets being discovered are called "Exoplanets" or "Extrasolar Planets" which means they are planets found outside of our solar system. New ones are constantly being discovered. We are currently getting closer to discovering one within the habitable zone of another star.
maybe because they have found more than 300 planets outside our solar system. But they all have been gas balls or can't be proven to be solid. Now a team of European astronomers has confirmed the first rocky extrasolar planet. so i think they think that it is interesting that it is the first rocky extrasolar planet.
We currently have the ability only to detect large planets that are close to their parent star, but as the technology progresses, we will be able to detect smaller planets, and planets that are further away. Also, astronomers have found systems of planets, meaning stars that have more than 1 planet.
No there is not the only one even close to earth is mars because they found traces of water on it.
