Identifying cluster of exoplanets between Deneb and Vega I noticed an interesting patern of exoplanets.
Is this a known phenomenon?
That's the field the Kepler telescope was observing during its primary mission (before the second reaction wheel failure). The shape is due to the detector array.
I.e. this is not a real pattern in the actual distribution of exoplanets, it's a consequence of how the observations were done.
