A straight line path from Earth to Neptune is around 2.8 billion miles. So at 100,000 mph it would take 27,900 hours - about 3.2 years.
However, spacecraft never take the straight line route for their journeys. A more efficient journey is achieved through a "slingshot" manoeuvre using the gravitational effect of the moon or another planet to accelerate the spacecraft towards its destination.
Neptune is approximately 2.73 billion miles from Earth.
The average distance from Neptune to the sun is about 2.8 billion miles.
Neptune is farther from Earth than the Moon. The average distance between Earth and the Moon is about 384,400 kilometers, whereas the average distance between Earth and Neptune is about 4.3 billion kilometers.
The minimum Earth-Neptune distance is approximately 4.36 billion miles. The maximum is 4.63 billion miles.
Neptune's average distance from Earth is about 2.7 billion miles (4.3 billion kilometers) when the two planets are at their closest approach. However, this distance can vary as both planets follow their elliptical orbits around the Sun.
Neptune is approximately 2.8 billion miles away from the Sun on average. The distance can vary due to the elliptical orbits of both Neptune and Earth around the Sun.
Neptune's diameter is about 30775.2724 miles.

Neptune is bigger than Earth. It has a diameter of about 30,775 miles, making it nearly four times larger than Earth.
The planet that is 2,793,100,000 miles away from the sun is Neptune. This planet wasn't discovered until the 1840s because its the only planet that can't be seen from earth without a telescope.
