Additional Notes:
Approximately 7,000 light years away, this double open cluster was recorded by Hipparchus, the Greek astronomer in 130 BC. The clusters contain high temperature, young stars and are separated by just a few hundred light years between them. Due to their age similarities, it is likely they both were created from the same material in the region.
