Our night sky would be teeming with many stars if we were living inside a globular cluster
Asked by Terry White

If we were able to move our entire Solar System and put it straight in the middle of a globular star cluster, like 47 Tucanae, our night sky would be teeming with many stars.
In the case of 47 Tucanae, which has millions of members, stars would still appear as points of light since, due to their distance, they would not have diameters that are easily resolved by the human eye. They would also be more than a thousand times brighter than Earth’s nighttime star, Sirius.

To live on an Earth in a globular cluster would mean that the cluster’s stars (if they were like our Sun) would combine to create a night sky at around 20 times brighter than Earth’s night sky at full Moon.
