No. Jupiter is a gas planet. It does not have a definite surface.
No one has walked on Jupiter. First, no one has ever traveled to the region of Jupiter. Second, if there is a solid surface to walk on, the conditions there would make it impossible with known or likely technology to survive a descent from orbit, let alone walk on the surface.
No, since Jupiter probably has no surface, and if it does have one, the environment there is too hot and too dense for anything to survive.
At the level in the atmosphere where the pressure is one (1) bar, Jupiter has an equatorial circumference of about 44384 miles. A standard walking pace for someone energetically walking distance is 4 miles per hour.At that rate, if there were a surface to walk on, and there is not one at that level, it would take a person 11096 hours or 924 Earth days (walking 12 hours per day) or a bit more than 2.5 years to walk around Jupiter, assuming you never took a day to rest or be ill.
No. There is no solid surface.
No one has been on Jupiter's surface as Jupiter is a gas meaning if a shuttle made it to Jupiter it would go straight through
No one has walked on Saturn. and since the planet is a so-called Gas Giant - no solid surface - no one ever will.
Actually, no. there may be a solid surface at the core of Jupiter, but you would not be able to stand on it. Well to get to it because going through all those gases Jupiter is made up of may seem easy... possible but you would actually be crushed by the pressure of it and die a horrible death.
Jupiter is one of the gas giants in our solar system. Without a helmet, you could not survive for more that a minute or so, depending on how long you could hold your breath. The surface atmosphere. is predominantly methane and ammonia.
No. Jupiter is a gas giant. There is no surface on which volcanoes might form. However, Io, one of Jupiter's moons, is covered in volcanoes.
No,, there have never been, nor will there ever be rovers on Jupiter. Jupiter is a gas planet. It has no surface on which to land. However, a rover might one day land on one of Jupiter's many moons.
There are lots of ifs in this question and answer. If the 100 pound Earth object could rest on the outer surface of Jupiter the answer would be 250 pounds. But, Jupiter is a gas planet. That is, Jupiter is primarily made of gas and liquid. So, the object could not rest on the outer surface. There may be a solid surface near it's center but no one knows. Jupiter is 318 times as heavy as Earth so if Jupiter were solid and the size of Earth the object would weigh 318 times a much or 31,800 pounds. But, it is much larger than Earth so the outer surface is much farther from the center. The farther away the object is from the center the less the object will weigh.
Jupiter has very little water (0.0004%).There is no LIQUID water on Jupiter because Jupiter is a gas giant. However, Jupiter DOES have evaporated water in its atmosphere and one of its moons, Europa, is said to have a frozen ocean on its surface.
