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.
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.
The moon is about 384,403 kilometers (238,857 miles) from Earth, and about 4,564 million kilometers (2,835 million miles) from Neptune. So, the moon is much closer to the Earth, Neptune over 10,000 times farther away.

The distance between Earth and Neptune varies depending on their positions in their orbits. On average, it is about 4.3 billion kilometers (2.7 billion miles).

On average, Neptune is about 2.7 billion miles (4.3 billion kilometers) away from Earth. The exact distance between the two planets varies as they both orbit the Sun on elliptical paths.
Neptune's diameter is about 30775.2724 miles.

The sun is much closer to earth than Neptune is. Neptune is way out there. The sun is 1 A.U. away or 92 milllion miles Neptune is between 29 - 31 A.U away
Neptune is located very far from the Sun, so it receives very little sunlight compared to inner planets like Earth. The amount of sunlight reaching Neptune is about 0.001 times the sunlight that reaches Earth.
