To find this star, go down from the Pleiades until you are above level with the sword of Orion, but it is a dim star (mag. 4.8) so you will be better off using go-to or a star chart to find it. The two stars are not equal – the primary is 4.8 and the secondary 5.9 – and they are a yellow and blue pair, although some observers see the secondary as green. With a separation of 6.9″, they are fairly close together and would benefit from a fairly high magnification, but they should be separated with a small to medium telescope. Although the separation has increased since the double was first recorded by William Herschel in October 1781 (H II 36), the position angle has hardly changed and unusually for a double star nowadays, it is still uncertain if it is a binary star or not. 32 Eridani is a triple star, but C is very dim (mag. 10.5) and will require at least a medium sized telescope; it is roughly at a right-angle to the closer pair and much further out at 164.7″.
