The complex is believed to be approximately 3000 light-years distant with the younger components aged no more than a few million years.The complex also includes one of the hottest stars discovered within 3,000 light-years of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity ~100,000 times that of the Sun.

The "dot" of the question mark is SH2-170, in Cassiopeia
