Neptune has 1.14 times Earth's gravity, so the ball would fall a little faster. How long it takes to fall depends on how high you drop it from. A ball dropped from from a height of 16 feet takes 1 second to fall to the ground on Earth and would take a little less than 0.94 seconds to fall the same distance on Neptune. But since Neptune is a gas giant planet, it has no real surface; no ground. So you would have to do the experiment in a balloon or aircraft in Neptune's atmosphere. For other facts see the sources.

The surface gravity of Neptune is only 1.14 g, or 14% more than Earth gravity. On Earth, it takes 5 seconds for a heavy ball to drop 800 feet. On Neptune, it would take only 4.68 seconds.

It would fall faster on Neptune than on Earth due to Neptune's higher gravitational pull. check out the website below.

About a half a second, if you dropped it from chest height. Neptune's gravity is only 1.19 that of Earth's, even though it is about 4 times the diameter of Earth. Neptune's diameter is about 30,000 miles and Earth's is about 8,000 miles.

Depends how high it starts from.
