Structure. The composition of Jupiter is similar to that of the Sun—mostly hydrogen and helium.
Deep
in the atmosphere, pressure and temperature increase, compressing the hydrogen gas into a liquid. This gives Jupiter the largest ocean in the solar system—an ocean made of hydrogen instead of water.
Why does planet Jupiter contain so much hydrogen?
In the gas giant’s outer layers, hydrogen is a
gas
just like on Earth. As you go deeper, intense atmospheric pressure gradually turns the gas into a dense fluid. Eventually the pressure becomes so great that it squeezes the electrons out of the hydrogen atoms and the fluid starts to conduct like a metal.
Why does Jupiter have more hydrogen and helium than Earth?
Large self-
gravity
means a large escape velocity, so it is much more difficult for molecules to reach the kinetic energy needed to escape the gravity of Jupiter than that of Earth. Jupiter therefore has a much greater concentration of hydrogen and helium than Earth does.
Is hydrogen abundant on Jupiter?
Jupiter boasts an enormous supply of
hydrogen
and helium that make it the most massive planet in the solar system.
Which planet has the most hydrogen?
Answer: The objects with the highest percentage of hydrogen are
the sun
, Mercury, Jupiter, Saturn, Uranus and Neptune. The objects with the least percentage are Venus, Earth, Moon, Mars, Titan, Pluto.
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.
Is Jupiter toxic?
The gases include nitrogen, hydrogen, helium, methane, and ammonia. …
Not all of these gases are poisonous
. Most of Earth’s atmosphere is nitrogen, and there is a little helium too. There is no oxygen on Jupiter like there is on Earth.
Is it possible to live on Saturn?
While
planet Saturn is an unlikely place for living things to take hold
, the same is not true of some of its many moons. Satellites like Enceladus and Titan, home to internal oceans, could possibly support life.
What is the oldest planet?
PSR B12620-26 b
The exoplanet known as PSR B12620-26 b is the oldest known planet in the universe, with an estimated age of about 13 billion years.
Can you walk on Jupiter?
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. … If you could stand on the surface of Jupiter, you would experience intense gravity. The gravity at Jupiter’s surface is 2.5 times the gravity on Earth.
Is there oxygen on Saturn?
It is a gas giant, in the sense that most of its mass is made of gas. Its observable atmosphere comprises about 90% hydrogen and 10% helium. … It is likely that Saturn’s interior contains lots of water, and thus oxygen,
possibly at the same proportion as helium
.

Is Jupiter hotter than Earth?
With an average temperature of minus 234 degrees Fahrenheit (minus 145 degrees Celsius),
Jupiter is frigid even in its warmest weather
. Unlike Earth, whose temperature varies as one moves closer to or farther from the equator, Jupiter’s temperature depends more on height above the surface.
Which is the only planet that can sustain life?
Understanding planetary habitability is partly an extrapolation of the conditions on
Earth
, as this is the only planet known to support life.
What is the hottest planet?
Planetary surface temperatures tend to get colder the farther a planet is from the Sun.
Venus
is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.
How hot is Jupiter?
It is estimated that the temperature of the cloud tops are about -280 degrees F. Overall, Jupiter’s average temperature is
-238 degrees F.
