Its transit was caught amongst Quarter 2 data, and we’ve confirmed that it repeats in later data. We can’t quite call this a planet yet, but with more than 95% certainty in our discovery it becomes an official planet candidate.
The second candidate is even more exciting. It orbits around the star KIC 10005758, has a 284 day ...
