A light year is defined as the distance which light travels in a year. This is therefore equal to 300,000,000m/s (speed of light) multiplied (365 x 24 x 60 x 60) = 9.46 x 1015m.

A stellar (globular) cluster is a group of stars which are close together in the universe due to gravity, as a result of them arising from the collapse of the same gas cloud. These clusters can contain from 100,000 to 1,0000,000 stars, ranging within distances of 30-100 light years across.
