%\item How common are planets similar to the Earth (Earth-like exoplanets)?
%\end{itemize}
The wealth of data provided by Kepler has revealed an astonishing fact: "When you wish upon a star, you are wishing upon a star with planets" (W. Borucki). There is
in on average \textbf{one planet orbiting every star in the Universe} \citep{2013ApJ...764..105S, 2012Natur.481..167C}. Just in our Galaxy this means we have 100 billions planets. Since we have about 100 billion galaxies in the Universe, there are about 10,000,000,000,000,000,000,000 = $10^{22}$ planets out there.
%To put it in the words of W. Borucki, Principal Investigator of the KEPLER satellite: "When you wish upon a star, you %are wishing upon a star with planets".
