Star Densities in Globular Clusters
Do not be mislead by images of globular clusters into overestimating their densities.
The star density in a globular cluster is higher than
that near the Sun (where the average spacing between stars is parsecs).
But even in the centers of dense globular clusters the average spacing between stars is
still of order 0.1 parsecs (several light months), which is
about 500 times further than the distance from Earth to Pluto.
However, the night sky would be quite
bright on a planet near the center of a dense globular cluster. On such a planet
we would
see many hundreds of stars as bright as the brightest few
stars in our present sky.
