Located in the constellation Capricornus, M30
is a globular cluster of stars located about 25,000 light-years
from Earth. This dense cluster is around 75 light-years in
diameter and contains 12 known variable stars. It is actually
approaching us at a speed of 164 kilometers per second. M30's
large size and dense structure make it a remarkable object when
viewed through binoculars or small telescopes.
