Globular Cluster “47 Tucanae”

Description:

47 Tucanae is the second largest globular star cluster in our galaxy, containing over a million solar masses. The cluster is 120 light years in width, and is 16,700 light years away in the southern constellation Tucana (the "toucan"). Stellar separation in the core, as with many globular clusters, is 1/10 light year or less, or 1,000 stars per cubic light year. Contrast that with the separation of 4.2 light years between our Sun and the nearest star.
