Neptune is about 17 times the mass of Earth.
Diameter : 33,000 miles Mass : 1.0243×1026 kg 17.147 Earths
Your mass stays the same but your weight is different because it is the force that the planet's mass attracts your mass with. So if you are on a small planet your weight is less. A body with 100 pounds mass has a weight of 100 pounds on the Earth but only 17 pounds on the Moon, and zero pounds in space.
Earth's Mass is 17 times less than neptune's mass.
To answer this we must start by taking a look at Neptune's mass. Neptune's mass is about 1.02 x 1026 kg. It would take over 17 Earths to fill up Neptune, but the gravity on Neptune is only 1.19 times of the gravity on Earth. This is because it is such a large planet (and the gravitational force a planet exerts upon an object at the planet's surface is proportional to its mass and to the inverse of its radius squared). A 100-pound person would weigh 112.5 pounds on Neptune. If the object is massive it will gain gravity but if it is large it will lose gravity at a greater rate.
yes. everything that has a mass has gravity, including urself. but on the moon the gravity is only 17% as strong as earths gravity

It is known as Wasp-17b, discovered in 2009. The planet is believed to have a radius 1.991 times (nearly double) that of Jupiter but a mass of only 0.486 times (less than half).
Neptune has a mass of 1.0243×1026 kilograms, or about 17.147 times that of Earth. Wikipedia has additional information, and a link is provided below to their post on this, the new "last planet" now that Pluto has been "demoted" to a planetary body. Neptune's density is 1.638 g/cm³. That means that in every cm cubed it weighs 1.638 grams.
The mass number is the sum of the numbers of protons and neutrons, 35 in this instance. The atomic number is the same as the number of protons, 17 in this instance.
