About 100 extrasolar planets are thought to have been discovered. All are giants and probably most resemble Jupiter
Jupiter NeptuneThe planet that most extrasolar planets resembles Jupiter.Jupiter(apex)Most of the confirmed Exoplanets are larger gaseous planets with large masses. These are easier to detect and confirm due to their size. They most resemble Jupiter, although many are thought to be much larger than our largest planet.
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.
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.
Mars The inner planets such as Mars, Earth or Mercury. these are too small to identify in other systems and too close to the star.
We tend to see the large planets farthest away from their stars. So it is unlikely we will find any small planets close to their star similar to Mercury.

So far. Jupiter and Saturn
Most of the known extrasolar planets are more massive than Earth because massive planets are easier to detect. We have detected planets smaller than Earth.
An extrasolar planet, or exoplanet, is a planet beyond our Solar System, orbiting a star other than our Sun. As of June 2009[update], 353 exoplanets are listed in the Extrasolar Planets Encyclopaedia . See http://exoplanet.eu/catalog-RV.php Most are unintelligible alphanumeric combination which are derivatives of the code assigned to the star in that "solar" system.
