The Bayer designation ρ Cancri (Rho Cancri) is shared by two stars in the constellation Cancer:
55 Cancri, or Rho1 Cancri (ρ1 Cnc) 58 Cancri, or Rho2 Cancri (ρ2 Cnc)
In Johann Bode’s Uranographia, the designation Rho Cancri is applied to five different stars:
ρ1 Cancri is 53 Cancri ρ2 Cancri is 55 Cancri ρ3 Cancri is 58 Cancri ρ4 Cancri is 67 Cancri ρ5 Cancri is 70 Cancri
Bode’s superscripted letters are now rarely used though, so the designations have been reverted to the original 2 stars. See also Pi Cancri
