It takes about 60 Earth's
A few planets have more than 15 moons. Take Jupiter, which has at least 63 of them. Saturn has 60 known moons, while Uranus has 27. I'm reading a 1987 book of date that says: Jupiter has at least 16, Saturn: 23 and Uranus, 15.
Approx 2.75 moons.
It is in some ways, but not in other ways. They both evolve around the same star and look blue from afar. However, Earth is a terrestrial planet and Neptune a Jovian one. Neptune also has more moons and is colder, while years take decades of earth-years.

"it takes 20 earth days to reach neptune from earth"
It takes roughly 6.4 Earth days for Neptune to rotate on it's axis.
The Earth's moon takes 27 days to orbit the earth (lunar cycle.) The moons of Jupiter, Saturn, Neptune and Uranus all have different times.
