That depends on where they are in their orbits of the Sun. At certain times they are on opposite sides of the Sun form each other and at other times they are on the same Side of the Sun so the distance between them is constantly changing.
This said, Mercury orbits at an average of about 0.39 AU from the Sun and Neptune at an average of about 30 AU from the Sun.
1 AU = 149597871 kilometers
Venus is far smaller than Saturn. Venus is the thrid smallest planet in the solar system, larger than Mars and Mercury, bust smaller than everything else. Saturn is the second largest planet. Only Jupiter is larger.
The orbital speed of Venus is around 35.0 km/s while the orbital speed of Neptune is approximately 5.4 km/s. Venus orbits much closer to the Sun than Neptune, leading to its higher orbital speed.
on average venus is 108,208,000 km from the sun
Here are all diameters of the planets. Mercury 4,880 km Venus 12,104 km Earth 12,756 km Mars 6,794 km Jupiter 142,984 km Saturn 120,536 km Uranus 51,118 km Neptune 49,532 km (Pluto is not classed as a planet anymore)

Average distances in km are; Mercury - 57,909,175 km Venus - 108,208,930 km Earth - 149,597,890 km Mars - 227,936,640 km Jupiter - 778,412,010 km Saturn - 1,426,725,400 km Uranus - 2,870,972,200 km Neptune - 4,498,252,900 km
Neptune is 4,504,300,000 km away from the sun.
Jupiter is 741,000,000 km away. Uranus is2,870,000,000 km away. Neptune is 4,500,000,000 km away from the sun.
on average venus is 108,208,000 km from the sun
Prilarily, it is because Venus is far closer to the sun than Neptune, about 40 times closer. As a result, Venus recieves about 1600 times more solar energy per square meter than Neptune does.
It gets as close as 4,452,940,833 km and as far as 4,553,946,490 km.
