Is there a solid surface on gas giants?
Unlike rocky planets, gas giants do not have a well-defined surface – there is no clear boundary between where the atmosphere ends and the surface starts! The gas giants have atmospheres that are mostly hydrogen and helium.
Do the gas planets have a surface?
These planets, like Jupiter and Saturn in our solar system, don't have hard surfaces and instead have swirling gases above a solid core. Gas giant exoplanets can be much larger than Jupiter, and much closer to their stars than anything found in our solar system.
Can you walk on the surface of a gas giant?
Since none of the gas giants has a solid surface, you cannot stand on any of these planets, nor can spacecraft land on them.
What gas giant has a surface?
The four gas giants (except Saturn perhaps which may be fully gaseous) have solid or liquid cores that have an actual surface. Jupiter's liquid core is about as big as the Earth and has about 10 Earth masses.
Is there a solid core in Jupiter?
According to most theories, Jupiter has a dense core of heavy elements that formed during the early solar system. The solid core of ice, rock, and metal grew from a nearby collection of debris, icy material, and other small objects such as the many comets and asteroids that were zipping around four billion years ago.
Can you step on Jupiter?
Jupiter is made up almost entirely of hydrogen and helium, with some other trace gases. There is no firm surface on Jupiter, so if you tried to stand on the planet, you sink down and be crushed by the intense pressure inside the planet.
Why do gas giants not solidify?
You'd think by now they would have cooled enough to change from a gaseous to a liquid (or solid) state. But they haven't. The main reason is that they are made of primarily hydrogen and helium, which need to get VERY cold to condense. A few degrees above absolute zero in fact.
Is there a solid surface on Jupiter?
Surface. As a gas giant, Jupiter doesn't have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter, it wouldn't be able to fly through unscathed either.
What planet rains diamonds?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
Could a spaceship fly through a gas giant like Jupiter?
According to Leigh Fletcher, an associate professor of planetary science at the University of Leicester in the United Kingdom, the short answer is "no." A spacecraft could not survive a trip through a gas giant.
Is there solid land on Jupiter?
As a gas giant, Jupiter doesn't have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter, it wouldn't be able to fly through unscathed either.
Can I stand on Jupiter?
Jupiter is made up almost entirely of hydrogen and helium, with some other trace gases. There is no firm surface on Jupiter, so if you tried to stand on the planet, you sink down and be crushed by the intense pressure inside the planet.
Does it rain diamonds on Jupiter?
New research by scientists apparently shows that it rains diamonds on Jupiter and Saturn. In fact the planets have the capability to create 1000 tonnes of diamonds a year.
What is Uranus core made of?
While most planets have rocky molten cores, the center of Uranus is thought to contain icy materials. The liquid core makes up 80 percent of the mass of the planet, mostly comprised of water, methane, and ammonia ice, though it only extends to about 20 percent of the radius.

Can Jupiter ever become solid?
No, Jupiter doesn't have a solid surface. It is the largest among planets but lacks a firm solid surface. If one tries to paraglide and land on the surface of Jupiter, he would fail to find a surface and would rather slide down through layers of gas, dust, vapor, and liquid and finally reach the hot core.
Does Mars have a solid surface?
Mars is a rocky planet. Its solid surface has been altered by volcanoes, impacts, winds, crustal movement and chemical reactions.
Is there another Earth with humans?
The Kepler space telescope identified the exoplanet, and its discovery was announced by NASA on 23 July 2015….Kepler-452b.

What planet has acid rain?
planet Venus The most acidic rain in the Solar System is found on the planet Venus, where the working fluid in the cycle of evaporation, condensation and precipitation is a sulphuric acid solution (rather than water, as on Earth).
Can you stand on Saturn’s rings?
While they look like giant discs, they're not a solid track at all. Instead, they're made of millions of chunks of ice, some as tiny as dust particles, others as large as buses. But if you were able to hike on one of Saturn's outermost rings, you'll walk about 12 million kilometers to make it around the longest one.
What rains Uranus?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
What rains on Mars?
Because of Mars' very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
Does it rain diamonds on Uranus?
The postdoctoral research at NASA's Goddard Space Flight Center explained that the high amount of methane in both Uranus and Neptune is the key factor why it rains diamonds on the two planets.
What is Mars core?
Mars has a dense core at its center between 930 and 1,300 miles (1,500 to 2,100 kilometers) in radius. It's made of iron, nickel, and sulfur.
Does it rain diamonds on Neptune?
The postdoctoral research at NASA's Goddard Space Flight Center explained that the high amount of methane in both Uranus and Neptune is the key factor why it rains diamonds on the two planets.

What planet has no solid surface?
Surface. Neptune does not have a solid surface. Its atmosphere (made up mostly of hydrogen, helium, and methane) extends to great depths, gradually merging into water and other melted ices over a heavier, solid core with about the same mass as Earth.
How can Jupiter have no surface?
As a gas giant, Jupiter doesn't have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter, it wouldn't be able to fly through unscathed either.
Does space ever end?
No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.
