How many planets do not have moons that orbit around them?

Of the eight planets in the Solar System, the only two that have no moons are Mercury and Venus. Earth has one moon, Mars two, and the gas giants Jupiter Saturn Uranus and Neptune have dozens between them - no one really knowing just how many there are as new ones are being discovered each year. The first member of the minor planets beyond Neptune - Pluto - is now not designated as a major planet. It has at least three moons. There are many more minor planets beyond Pluto that have moons - and again these are being discovered yearly.
