Kepler-33b is an extrasolar planet orbiting Kepler-33 in the constellation Cygnus. It is one of five planets orbiting Kepler-33.
Discovery
Kepler-33b was, along with twenty-six other planets in eleven different planetary systems, confirmed to be a planet on January 26, 2012.[1][4]
The Kepler-33 system
Kepler-33b orbits its host star with 4 other planets. All five planets orbit its star closer than Mercury does to the Sun.[5] Of those five, Kepler-33b is closest.[4] All Kepler-33 planets are too close to be in the habitable zone.[6]
