I think the question means "how close" to the Sun. The nearest Neptune gets to the Sun is about 4,453 million kilometers. Its orbit is fairly close to being a circle, so the farthest it gets from the Sun isn't much different.
Neptune is 4,504,300,000 km away from the sun.
The average distance of Neptune from the sun is 2,795,084,800 miles or 4,498,252,900 kilometers.
The farthest Neptune gets from the sun is about 2.819 billion miles (4.537 billion kilometers.)
Considering you mean the farthest, Neptune is the farthest planet from the Sun. Totaling to 2,795,084,800 miles.
4540 million kilometres.
Neptune is located 2,798,000,000 miles from the Sun. This is equal to 4,503,000,000 kilometers from the Sun. Neptune is the farthest planet in the Solar System.

No. Neptune is too far from the sun to have become tidally locked. Neptune rotates quickly, as do the other gas giants in the solar system.
Neptune is approximately 2.7 billion miles away from the Sun.
About 30 AU from the Sun. Since Earth is 1 AU from the Sun, Neptune can be between 29-31 AU from the Earth.
Neptune is approx 19.7 times as far.
