Bang, zoom, straight to the moon!

Wednesday's One Cup of Java Challenge: When it comes to moons, Earth has one but our solar system has many. Your One Cup question this morning – within 50 either way, how many moons are known to orbit the eight planets of our solar system?

Answer: 166 (additionally, there are as many as 74 other "moons" that are not in fixed orbits around planets in our solar system).
