Gravity is what keeps us grounded – from all points of view. It is also the reason why the average person can jump only about 6 ft 6 in – 7 ft 5 in far. Gravity is determined by the speed of objects accelerating towards the planet’s surface.
Earth’s gravity, also referred to as normal gravity, is represented by an acceleration of 32.2 ft/s2. This means that as soon as you jump and break contact with the surface you’re sitting on, you’re being pulled back down with force equal to the mentioned number – or with 1 g of force.
Neptune has a volume equal to about 60 Earths and a mass of about 17 Earths. Interesting things could happen to a human on its surface, right? Let’s see how far you could jump and how strong you’d be on the surface of this planet!
What factors influence the distance of a long jump?

Horizontal velocity developed in the run-up and the vertical velocity during take-off are some of the main factors that influence the distance of a jump.
There is an equation that can help you determine the distance of a jump. It considers take-off velocity, jump angle at take-off, acceleration caused by gravity, and take-off height changes. Out of these values, the last two are often considered constant, especially in the case of a professional jumper. Highly trained athletes keep a constant take-off height, while gravity is constant across our planet. The only things that can change are take-off velocity and take-off angle.
Naturally, things are bound to change when subject to different gravity. Let’s see how things would work on Neptune!
What is the exact gravity on Neptune?

The exact gravity on the surface of Neptune is 36.58 ft/s2 – or 1.14 g. It is about 114% the gravity of Earth – or 14% stronger. A 10 lbs object on Earth would weigh about 11.4 lbs on Neptune. This value influences the weight of objects (not their mass), your ability to jump, as well as your overall strength.
Neptune is one of the planets with a stronger gravitational force than Earth. As a result, you’d be pulled back to the planet’s surface much faster and earlier than on our planet. Because of this, you can’t jump very far on the surface of Neptune. At the same time, you’d have a difficult time lifting certain objects. A 110 lbs object would weigh 11.4 lbs more on Neptune.
For comparison purposes, the gravity on the Moon is 5.31 ft/s2 – or 0.166 g. It is about 16% the gravity of Earth – or 84% weaker. You can refer to the famous moon walking videos to get an idea and a starting point for the matters in question here.
How far and high could you jump on the surface of Neptune?

In theory, you could jump approximately 1.41 ft high on Neptune from a standing position and spend 0.56 seconds in the air. On Earth, you can jump about 1.64 ft high and spend 0.63 seconds airborne. This means that, on Neptune, you can jump about 0.87 times as high and far as on Earth – in short, your jump will be shorter.
Neptune has a mass of about 17 Earths. This is one of the main reasons why gravity is stronger there. A stronger gravitational force means that you’ll have a slightly more difficult time building up speed.
In theory, according to the data presented here, you could jump 77.43 inches far on the surface of Neptune – 87% of an approximate average 7 ft 5 in (89 inches) jump on Earth. On our planet, this would make you a below-average jumper.
How far and high could you jump on the surface of every planet in our Solar System?
Here is how far and how high you could jump on the surface of every planet in our Solar System:
How strong would you be on the surface of Neptune?
In theory, you’d be approximately 0.87 times (less) as strong on the surface of Neptune. On this planet’s surface, 10 lbs feel like 11.4 lbs. The greatest weight ever lifted, 6,270 lbs, would weigh about 7,147.8 lbs on Neptune.
The gravity on Neptune is 14% stronger than Earth’s. While this number may seem small, it might affect astronauts more than you think. If we consider the mass of a 14% heavier object, then vehicles could become impossible to move if stuck, for example.
What planet could you jump the farthest and be the strongest on?
Pluto is the planet you’d be the strongest and jump the farthest on. The planet’s gravity is a mere 6% of Earth’s – about 0.063 g. A 100 lb object would weigh only 6 lbs on Pluto – this could make any of the planet’s visitors a real strongman. As for jumping, breaking contact with the planet’s surface by hopping on it would keep you in the air for about 10 seconds.
