Kepler-41b, formerly known as KOI-196b, is a planet in the orbit of star Kepler-41. It is a hot Jupiter with about the density of water. It reflects about a third of the starlight it receives. The brightest spot in the planetary atmosphere is shifted westward from the substellar point, indicating strong winds.{{citation|arxiv=1504.00498|title=Studying Atmosphere-Dominated Hot Jupiterkeplerphase Curves: Evidence That Inhomogeneous Atmospheric Reflection is Common|year=2015|doi=10.1088/0004-6256/150/4/112 |last1=Shporer |first1=Avi |last2=Hu |first2=Renyu |journal=The Astronomical Journal |volume=150 |issue=4 |page=112 |bibcode=2015AJ....150..112S |s2cid=33182939 }}
