Physical characteristics

In 2009 an astronomical study by Bidin et al concluded that whereas the small group of stars in Aquila had been classified as an OCR (Open Cluster Remnant ie the dispersed remains of a group of physically related stars) they were in fact an asterism, a group of unrelated stellar bodies.[2]
