Astronomy:Psi Cancri

From HandWiki

The Bayer designation Psi Cancri (ψ Cnc, ψ Cancri) is shared by two star systems, separated by 0.34° on the sky, in the constellation Cancer:

  • ψ¹ Cancri
  • ψ² Cancri, which is often referred to solely as ψ Cancri

Johann Bode designated the star 15 Cancri as ψ3 Cancri, despite the distance from the other two. It was given the designation due to Johann Bayer’s original Uranometria designating it as ψ Geminorum.
