Uranus
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.

They least resemble rocky planets like Venus Earth and Mars, particularly they least resemble planets that we would consider as possible life sustaining planets.
This question is impossible to answer. As of today, 11th April 2011, there are over 540 known extrasolar planets - each one is different in it's own unique way. The only answer, based on today's knowledge, is that none - so far - are like the inner planets but that is due to our technology rather than the actual planets.
It was not "found out" but a decision that was made by a panel of planetary experts to define what is a planet and what is not which "degraded" Pluto from planet status of "dwarf planet" on August 24, 2006.There are at least 44 dwarf planets known.
Mercury is the smallest planet in the Solar System
The solar system, however there are not 9 major planets anymore Pluto got down graded to a dwarf planet.
Saturn is the least dense planet in our solar system.
All of them are - at least, the planets in the Solar System.
