That all depends on whether or not you're planning to orbit the moon. Spacecrafts have flown to the moon in as little as 9 hours, but they just flew past it. To enter orbit, a vehicle has to travel a lot slower. Apollo 8, the first manned lunar flight, took 69 hours to reach the moon.
The moon takes 29 days or so to orbit our planet.
The moon's orbital period around Earth is about 27.3 days. This is known as the sidereal month.
No planet, but the Moon takes that time to orbit the Earth.
It depends which planet you mean.
The moon is already close to the earth
Many planets have only one moon. For example, Earth only has one moon. There are likely to be billions of planets in our universe with just one moon. As you can imagine, the list of these would take a long time to write out. We will only have discovered a small amount of actual planets that fit this description though.
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.
