A well-known optical double star, whose pale blue components exhibit completely different proper motions, resulting in a relatively significant change in their mutual position over time. In 1830, their mutual separation was 26", but by 1960 they had approached each other to a distance of only 9", and since then their separation has gradually increased again. The primary star has a magnitude of 3.1 and the companion has a magnitude of 8.2. To resolve this rare pair, a telescope with a 6 cm objective diameter will suffice.
