5,000,000,000,000,000,000,000,000,000,000,000 million miles an hour
2,400 km per hour
it would take about 12 weeks
No
2100km
Have human or human made objects travel to neptune
it takes Neptune 165 earth years to orbit the sun

Or If you want to be even more precise than that , how fast you are going to accelerate, the speed your going to travel at, What time and date because the planets are in motion. I will be happy to help you solve this with a little more input.
