A complex multiple system with an unusually large number of component stars. At the heart of the system is a binary circled by a third star in a relatively close orbit, and beyond this grouping there are at least three further companions following orbits progressively more distant from the central triplet.
Visible in the far east (left) of this image is the dark shape of the Horsehead Nebula, while the bright light of Alnitak in Orion's Belt can be seen shining on the northern edge of the frame. Imagery provided by Aladin sky atlas
* Distance data for the members of this group of stars covers a wide range of values, and with significant error margins. The entire group seems to be centred on a point about 1,275 light years (391 parsecs) from the Sun, but different measurements place the individual component stars within a considerable range of possible distances around this estimated point.
