NotesThe core of this system comprises a binary pair of white main sequence stars in a close orbit, about fourteen AU apart. There is also a third member of the system, a dwarf star in a more distant orbit. The system is not physically related to Iota2 Normae, which lies nearby in the sky, but is actually more than twice as far from the Sun as Iota1.
