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 is about 2.7 billion miles from Earth, or 4.3 billion kilometers. Neptune is the eighth planet from 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.
Neptune is 30.069 miles away from the sun Earth 9 million
The minimum Earth-Neptune distance is approximately 4.36 billion miles. The maximum is 4.63 billion miles.

The Earth is about 2.7 billion miles from Neptune. This distance increases when the planets are on either side of the sun during their orbits.
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, the planet that is the farthest known of the solar system, if you discount Pluto, is located 30.047 times farther away from the Sun than Earth is, at 2,793,100,000 miles, while earth is 93,000,000 miles from the Sun. Only about one thousandth of the Sunlight received by Earth reaches Neptune. Yet, with that small amount of sunlight the atmosphere of Neptune is significantly affected. To sum this up, Neptune only gets about 1/900 the sunlight of earth.
