HD 34445 b is an extrasolar planet which orbits the G-type star HD 34445, located approximately 150.5 light years away in the constellation Orion. This planet was discovered in 2004 and finally confirmed in 2009. This planet has a minimum mass two-thirds that of Jupiter and orbits in a roughly circular orbit about 2 AU from the parent star, within the habitable zone.
