HD 37124 d is an extrasolar planet approximately 103 light-years away in the constellation of Taurus. The planet was discovered in 2005 orbiting the star HD 37124 in a long-period orbit. Based on its mass, it is considered to be a gas giant. An alternative solution to the radial velocities gives a period of 29.92 days and a minimum mass 17% that of Jupiter.[1]
