Beyond the makeup of our atmospheres, Earth is very similar to Venus. Nearly identical in size and density. In fact, the only two planets which really share many of the same characteristics are Uranus and Neptune, but even they have their unique qualities.
There's certainly no other planet like Mars...none other like Mercury. Jupiter is decidedly the one planet least like any other though Saturn is also in a class of its own.

The definition of a planet, as decided by the IAU on the 24th of August 2006, is a celestial body that dominates it's own orbit and can sustain a round shape.
Pluto fails to dominate it's own orbit as it crosses into Neptune's for about 20 of our years, therefore removing it from the class of planet.

uh that's not the consideration. first is size and shape next is a predictable orbit and having the power to keep that stable (and have satelites if possible)
