description HD 37124 d Overview
HD 37124 d is a giant exoplanet associated with HD 37124, a Sun-like star about 108 light-years from Earth. It was announced in 2005 from radial-velocity observations and is described as the outermost member of the system's three known planets. Its position in the system gives it a longer orbit and lower stellar heating than the inner companions, which is why catalogs often classify it as a cold outer giant. The planet was detected indirectly through the motion of its host star.
