NGC 6755 is an open cluster of stars in the equatorial constellation of Aquila, positioned about 3° to the east of the star Delta Aquilae.

[2] It was discovered by the Anglo-German astronomer William Herschel on July 30, 1785[5] and is located at a distance of 8,060 light years from the Sun.

However, they probably do not form a binary cluster system since they have different ages and are too distant from each other.

[2] This cluster has a Trumpler class of II2r with a visual magnitude of 7.5 and it spans an angular size 15′.

[2] It has an estimated age of 250 million years, based on the main sequence turnoff.
