Messier 2 or M2 (also designated NGC 7089) is a globular cluster in the constellation [[Aquarius]], five degrees north of the star Beta Aquarii. It was discovered by Jean-Dominique Maraldi in 1746, and is one of the largest known globular clusters. M2 is about 37,500 light-years distant from Earth. At 175 light-years in diameter, it is one of the larger globular clusters known. The cluster is rich, compact, and significantly elliptical. It is 13 billion years old and one of the older globulars associated with the Milky Way Galaxy. | Messier 2 or M2 (also designated NGC 7089) is a globular cluster in the constellation [[Aquarius]], five degrees north of the star Beta Aquarii.
