Looking like globe-shaped cotton balls, the known globular clusters number about 125 in our own galaxy. They are distributed spherically around the galaxy, but are more concentrated near the Galactic center.
Globulars are old - evidence for this is that the brightest stars are red. RR Lyrae variable stars abound in globulars.
Globulars range in size from a little under 100 light years across to about 400 light years. Their stars number from tens of thousands, up to hundreds of thousands.
Most globulars orbit the center of the Milky Way on eccentric and highly-inclined orbits.
