Question: What planet are people wanting to know more about and why?

At the moment with all the recent explosion in new planets being found around other stars we are most interested in finding Earths twin. We are trying to find the best planet that might have life. So far some of the best ones we have around stars like our own Sun are (apologies for the boring names) Kepler-186f, Kepler-62f and Kepler-442b.

However, it is also known that some planets are orbiting multiple stars and are the same size as Saturn and Jupiter. These planets can have a moon the size of Earth and have a much better chance of supporting life due to the extra energy in these systems. Keeps the moon / planet warmer further away from the star. Kepler-16b is a good example of this.
