If you are worried about your weight, do not go to Jupiter. The Jovian gravity is much more intense than Earth’s. 2.528 times more intense to be exact. That means if you weigh 100 kg on Earth, your weight on Jupiter would be 252.8 kg.
Of course, you can not stand on the surface of Jupiter. Jupiter is composed of about 90% hydrogen and 9.99% helium. The gaseous nature of the planet makes a solid surface impossible. Scientists have devised a way to define the surface of Jupiter, though. The surface of the planet is defined as the point where the pressure of the atmosphere is 1 bar, which is equal to the atmospheric pressure at Earth’s surface. That point is at the tops of Jupiter’s clouds.
Now that we have defined your weight on Jupiter, let’s move to on some other interesting facts about the planet. To start off, even though it is the largest planet in our Solar System, it is not the largest planet that we know of. While there are several planets larger than Jupiter, the largest known to man is TrES-4. TrES-4 is 70% larger than Jupiter, but is quite a bit less massive. Scientists think that it has a structure similar to cotton candy for lack of a better analogy.
Since Jupiter’s gravity is so intense, it has trapped quite a few moons. The are 63 acknowledged Jovian moons and there are a few others being studied, so that number could go up at any time.
Jupiter has a system of rings. Many people are surprised to find out that Saturn is not the only ringed planet in our Solar System. In addition to Saturn; Jupiter, Uranus, and Neptune have rings. Rings are generally formed by dust and debris left orbiting after a meteorite impact on a moon. With so many moons, you would think that Jupiter would have a bunch of rings. It only has four defined rings, though.
A day on Jupiter is just under 10 Earth hours long, but a single years lasts 11.86 Earth years.
Some scientists think that Jupiter’s gravity is intense enough to affect the Sun. They believe that when Jupiter is at its closest approach to the Sun, solar flare activity increases. Others believe that Jupiter’s gravity may eventually push Mercury our of our Solar System.
Now that you know what your weight on Jupiter would be, we hope that you will want to research more Jovian facts.
