Non identical twins

There have been a few recent items in the news concerning 'twin' planets for our very own earth. They centre discoveries in other solar systems of planets of similar size and composition to the earth together with speculation that perhaps we could live there one day, or perhaps they contain life too.

Actually what they highlight is how special the earth is. For example these two recent discoveries are 'hot as hell'.
