The bright star in the centre of this image is the yellow giant Iota Cancri A, with the fainter Iota Cancri B discernable to its immediate northwest. Based on their individual parallax measurements, these two stars lie as far as ten light years apart, but their shared motion through space suggests that they are nonetheless gravitationally related to one another.
