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]
