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 about 2 AU from the parent star. However this planet orbits in a very eccentric path. The planet's distance from the star ranges from 0.86 to 3.16 AU however it spends its full orbit within the star's habitable zone.
