Are There Planets Out There for Us?

It is difficult to know which Physics problems will be solved soon. String theory has many solutions, but not a single chosen one agreeing with most data. Planetary formation models can give little planets, big planets, some in between, but can they find and explain one just like ours? It seems that more data is needed, and more money and time spent. I hope they finish before we are through with this Earth of ours.
