NGC 1978
NGC 1978 is an elliptical shaped globular cluster or open cluster in the constellation Dorado constellation. It is located within the Large Magellanic Cloud. It was discovered by James Dunlop on November 6, 1826, and its apparent magnitude is 9.9, and its size is 3.9 arcminutes. Its radial velocity is 293.1 ± 0.9 km/s.
The northwest half of NGC 1978 is iron-rich and younger whereas the southeast part of the cluster has very little iron. NGC 1978 is also highly elliptical, suggesting tidal action between it and the Large Magellanic Cloud. NGC 1978 is rich in pulsating asymptotic giant branch stars, often oxygen-rich or carbon-rich.
