NotesWhile not physically related to Prima Hyadum, both stars are part of the Hyades cluster, and close together in space. Secunda Hyadum is yellow-orange in colour (and indeed some sources classify it as a K-type orange star rather than a G-type yellow) with a small stellar companion orbiting at a distance of less than 2 AU.
