The first planetary system has been found with the Kepler K2 mission. Three main points about why this is really exciting:
1) It is close by, so we can follow up and look at the planets' atmospheres and figure out which ones are rocky and which ones are Mini-Neptunes.
2) The outermost orbits are almost exactly at the inner edge of the empirical Habitable Zone, which could indicate a super-Venus or super-Earth, depending on atmosphere and cloud coverage.
3) It shows that we can still find many such systems with the Kepler K2 mission.
If it were a bit further out, the third planet would be smack in the Habitable Zone. Maybe the next system...(fingers crossed) -- it's exciting.
