This asterism (not a real star cluster) is made up of 10 stars from 5th to 7th magnitude which form a "coathanger".
Brocchi’s Cluster is listed in many texts as having been discovered by Italian astronomer Giovanni Battista Hodierna in 1654, and it is named for American amateur astronomer Dalmero Francis Brocchi, who created a map of it in the 1920s. However, the first recorded unaided eye sighting was by famous Persian astronomer ’Abd al-Rahman al-Sufi in 964.
Under a dark sky can be seen at the naked eye.
