The Bayer designation Rho Herculis (ρ Her / ρ Herculis) is shared by two stars, in the constellation Hercules:

The designations ρ1 and ρ2 are rarely seen. The two stars are only separated by four arc-seconds and cannot be separated by the naked eye and are more commonly referred to as ρ Herculis A and B. They both have the same Flamsteed designation 75 Herculis, Hipparcos catalogue number 85112, and Bonner Durchmusterung designation BD+37°2878, but different HR and HD numbers.
