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.
Most extrasolar planets are found close to their parent stars because current planet detection methods are biased towards detecting larger planets that are closer to their stars due to the limitations of technology. These close-in planets are easier to detect because they have a greater impact on their star's light or motion. As technology and detection methods improve, we are discovering more distant planets from their stars.
Most extrasolar planets are found close to their parent stars because of the methods used to detect them, such as the transit method and radial velocity method, which are more sensitive to planets located closer to their stars. Additionally, the intense heat and radiation from the parent star can cause planets to migrate closer over time through processes like orbital decay or gravitational interactions.
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.
Observing a star carefully enough to notice that it is experiencing a gravitational tug caused by an unseen planet. Another possibility: The "transit " method was used very effectively in the Kepler space mission. I think that may be the main method to date.

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.

No there is not the only one even close to earth is mars because they found traces of water on it.
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.
To get a direct image of a planet, we need to gather the light it is reflecting. Planets in our own solar system are much closer and thus, they appear bigger - and they can often be found far enough away from where the Sun appears to be, so that the Sun's light doesn't affect the imaging effort.However, when a star is many light years away, and a planet is around it, it will appear very, very close to its parent star - which is essentially blinding it out.Imaging trying to gather the light reflected off a grain of sand which is sitting next to a large flashlight shining in your face.
