Could a liquid planet exist?
It is probably not possible for a planet to be entirely liquid. This is because a planet needs to be ‘self-gravitating’ so that it holds its spherical shape under gravity. However, it is possible for a planet to be entirely covered by liquid over a solid core.
What planet has solid liquid and gas?
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.
Can gas planets exist life?
The primary composition of Gas Giants are Hydrogen and Helium. We know only of Life made of Carbon based compounds. With limited Carbon, Nitrogen and Oxygen, life can’t exist as we know it.
Which planet is mostly liquid?
Earth is the only known planet to have bodies of liquid water on its surface.
What planet is mostly gas?
The planet Jupiter, Saturn, Uranus and Neptune are sometimes called the Gas Giants because so much of the mass of these planets consists of a gaseous atmosphere.
Can humans live on a gas giant?
At the innermost layers of Jupiter that are 13,000 miles deep, the pressure is 2 million times stronger than what’s experienced at sea level on Earth, and temperatures are hotter than the sun’s surface. So clearly, no human is going to be able to venture too far down into Jupiter’s depths.
Why are some planets gas and some solid?
The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system, only substances with very high melting points would have remained solid.
Is the Earth a liquid planet?
Earth’s inner core is solid nickel-iron despite being extremely hot. Water sublimates directly from ice to gas without pressure. A liquid planet would need to be the appropriate balance of heat and pressure to exist. Without, it would be solid or gaseous.
What are some examples of liquids on other planets?
Liquid methane is abundant in Uranus and Neptune. Bear in mind that liquidity is a matter of pressure as much as it is a matter of temperature. Earth’s inner core is solid nickel-iron despite being extremely hot. Water sublimates directly from ice to gas without pressure.
Could this be the core of a gas planet like Jupiter?
It could be the core of a gas world like Jupiter, offering an unprecedented glimpse inside one of these giant planets. Giant planets like Jupiter and Saturn have a solid planetary core beneath a thick envelope of hydrogen and helium gas. But no-one has previously been able to see what these solid cores are like.
What is a planet’s solid core like?
Giant planets like Jupiter and Saturn have a solid planetary core beneath a thick envelope of hydrogen and helium gas. But no-one has previously been able to see what these solid cores are like.
