| Beta Tucanae is a complex and confusing multiple star system.
Without trying to sort out the complications, we'll just mention that β1 and β2 form a fine binocular double with β3; all blue-white stars:
beta1,2 and beta3: 4.3, 4.5; PA 168º and a separation of 27.1". Confusion arises when one tries to sort out the names of the various members of this group, with B and C assigned to different stars depending on your reference. These three stars each have their own companion as well making the whole system at least six stars. The stars are east of alpha Tucanae a little over half way to Achernar (alpha Eridani) and a bit to the south: binoculars, forming a small triangle with zeta and rho. |
