All of them.
Every planet is likely to be unique. The chances that there is another planet in the galaxy that is exactly like the Earth is vanishingly small.
Or, perhaps not. 30 years ago, astronomers thought that planets were probably rare, that a solar system like ours with nine planets would be very unusual. Now, from the Kepler Space Telescope, we've discovered that planets are as common as, well, dirt. Every time NASA focuses on a planet that COULDN'T POSSIBLY have any planets, they discover one, or five, or a dozen.
Perhaps the forces that made our Sun the way it is inevitably leads to a planetary system similar to ours. I wouldn't bet on it, but the key thing in science is to be able to admit "We don't know - yet!"
