NGC 6834 is a young[6] open cluster of stars located about 10,850[2] light years from the Sun in the constellation Cygnus. It was discovered on July 17, 1784, by Anglo-German astronomer William Herschel.[7] The cluster has a visual magnitude of 7.8, which is dimmed by 2.1 magnitudes due to interstellar dust.[3] Half the cluster members lie within an angular radius of 6′.[2]
The Trumpler class of this cluster is II 2 m, indicating it is medium-rich in stars (m) with a moderate brightness range (2) and little central concentration of the stars (II).[6] It has about 260 members[2] and an age of approximately 65 million years,[4] although estimates range from 50 to 80 million.[6] A total of fifteen B-type variable stars have been detected in the cluster with four Be stars. Five of the cluster members show hydrogen alpha emission, including a γ Cas and two λ Eri variables.[6]
