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.[2] The brightest spot in the planetary atmosphere is shifted westward from the substellar point, indicating strong winds.[3]
