Earth has one moon and mars has two moons. how many more moons are found around the outer planets than the inner planets?

The outer planets are Jupiter, Saturn, Uranus and Neptune while the inner planets are Mercury, Venus, Earth, and Mars. The outer planets have more moons than the inner planets because these planets are much larger than the inner ones. The inner planets are terrestrial while larger ones are called gas giants, mostly made up of gas.

The correct answer is 140 moons.
