[2] The open cluster NGC 1907 lies nearby on the sky, but the two are most likely just experiencing a fly-by, having originated in different parts of the galaxy.
[1] The cluster's brightest stars form a pattern resembling the Greek letter Pi or, according to Webb, an "oblique cross".
Walter Scott Houston described its appearance as follows:[6] Photographs usually show a departure from circularity, a feature quite evident to visual observers.
A view with a 24-inch reflector on a fine Arizona night showed the cluster as irregular, and the host of stars made fruitless any effort to find a geometrical figure.At its distance of 1066 pc., its angular diameter of about 20 arc minutes corresponds to about 4.0 parsecs (13 light years), similar to that of its more distant neighbor M37.
[2] From the population of about 100 stars,[7] this open cluster features a prominent yellow giant with the apparent magnitude +7.9 and spectral type G0 as its brightest member.
