Jupiter is a gas giant, so it has no solid surface just a core of liquid metals..
Accordingly, which planets have a hard surface?
The planets in our solar system are divided into inner planets ( mercury, venus, earth, mars) and outer planets (jupiter, uranus,neptune and saturn). All the outer planets do not have a solid surface and they have a liquid metal core.
Subsequently, question is, which planet have a rocky surface? The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth's terra firma. The terrestrial planets are the four innermost planets in the solar system.
Similarly, you may ask, which planet has the most solid surface?
Jupiter
What are the surfaces of the planets like?
Terrestrial planets are Earth-like planets made up of rocks or metals with a hard surface. Terrestrial planets also have a molten heavy-metal core, few moons and topological features such as valleys, volcanoes and craters.

Is Jupiter hot or cold?
The temperature in the clouds of Jupiter is about minus 145 degrees Celsius (minus 234 degrees Fahrenheit). The temperature near the planet's center is much, much hotter. The core temperature may be about 24,000 degrees Celsius (43,000 degrees Fahrenheit). That's hotter than the surface of the sun!What planets can we land on?
Planets - Mercury.
- Venus.
- Mars.
- Jupiter.
- Saturn.
- Earth's Moon.
- Moons of Mars.
- Moons of Saturn.
Can we land on Jupiter?
A major problem in sending space probes to Jupiter is that the planet has no solid surface on which to land, as there is a smooth transition between the planet's atmosphere and its fluid interior. Any probes descending into the atmosphere are eventually crushed by the immense pressures within Jupiter.Is Jupiter a failed star?
"Jupiter is called a failed star because it is made of the same elements (hydrogen and helium) as is the Sun, but it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium, the energy source that powers the sun and most other stars.Does Jupiter have a solid crust?
Jupiter is primarily composed of hydrogen with a quarter of its mass being helium, though helium comprises only about a tenth of the number of molecules. It may also have a rocky core of heavier elements, but like the other giant planets, Jupiter lacks a well-defined solid surface.Can you land on Saturn?
Surface. As a gas giant, Saturn doesn't have a true surface. The planet is mostly swirling gases and liquids deeper down. While a spacecraft would have nowhere to land on Saturn, it wouldn't be able to fly through unscathed either.Can you stand on Uranus?
You can't stand on Uranus That's because Jupiter, Saturn, Uranus and Neptune don't have solid surfaces - they have a rocky core, but are mainly big balls of hydrogen and helium.Can you land on a gas giant?
Unlike rocky planets, which have a clearly defined difference between atmosphere and surface, gas giants do not have a well-defined surface; their atmospheres simply become gradually denser toward the core, perhaps with liquid or liquid-like states in between. One cannot "land on" such planets in the traditional sense.Is there water on Jupiter?
Scientists' consensus is that a layer of liquid water exists beneath Europa's (moon of Jupiter) surface, and that heat from tidal flexing allows the subsurface ocean to remain liquid.Can you walk on Jupiter?
We do not yet know if a solid surface exists on Jupiter. Jupiter's clouds are thought to be about 30 miles (50 km) thick. So, if it is a solid surface, it's not at all like what you would find on a rocky planet, and it's not something you could walk on.Is Uranus solid?
The surface of Uranus Like the other gas giants, Uranus lacks a solid, well-defined surface. Instead, the gas, liquid, and icy atmosphere extends to the planet's interior.Does Saturn have a solid core?
Like Jupiter, Saturn is suspected to have a rocky core surrounded by hydrogen and helium. However, the question of how solid the core might be is still up for debate. Though composed of rocky material, the core itself may be liquid. Research suggests that Saturn's rocky core is between 9 to 22 times the mass of Earth.Does Jupiter have rings?
Yes, Jupiter does have faint, narrow rings. Unlike Saturn, which has bright ice rings, Jupiter has dark rings which are made up of dust and tiny pieces of rock. Jupiter's rings were discovered by NASA's Voyager 1 mission in 1980.Which planet has water found in its polar ice caps?
The planet Mars has two permanent polar ice caps.Which planets in our solar system are solid?
The Solar System has four terrestrial planets: Mercury, Venus, Earth, and Mars.Does Venus have a solid surface?
Venus is a rocky planet, much like the Earth. The planet spins very slowly — once every 243 Earth days — and the core may not spin fast enough to create a magnetic field the way the core of Earth and other planets do. The core may also be completely solid, or may not even exist at all.What is Saturn made of?
Saturn is not solid like Earth, but is instead a giant gas planet. It is made up of 94% hydrogen, 6% helium and small amounts of methane and ammonia. Hydrogen and helium are what most stars are made of. It is thought that there might be a molten, rocky core about the size of Earth deep within Saturn.Can Europa support life?
So far, there is no evidence that life exists on Europa, but Europa has emerged as one of the most likely locations in the Solar System for potential habitability. Life could exist in its under-ice ocean, perhaps in an environment similar to Earth's deep-ocean hydrothermal vents.Is Earth losing water?
Earth is not losing water at a meaningful rate because Earth, unlike Mars, has a cold trap in the stratosphere that freezes out most water and keeps it closer to the Earth's surface.
