Pluto
Earth is the planet that is mostly made of liquid water, covering approximately 71% of its surface.
It is mostly solid. Earth has a solid crust, amtle, and inner core. However, the outer core is liquid.
Neptune is mostly made of gas. Also, Neptune has rings and clouds. BY: jill the queen of awesome
No. As of 2010, the dwarf planet Eris seems to be somewhere between −243 and −217 degrees Celsius, and appears to be made mostly of methane, which is solid at those temperatures.
Mars is known as the red planet. The planet itself is mostly rock. It is the thin atmosphere that is mostly carbon dioxide.
A gas giant is a large planet that is made up mostly of gaseous and liquid substances , with little or no solid surface.
Liquidifi
The question seems poorly worded, but Earth is the planet with liquid water on its surface.
The element Mercury is liquid at STP. The planet Mercury is a rocky or terrestrial type planet.
The planet you are referring to is Uranus, the seventh planet from the Sun. It is composed mostly of hydrogen and helium, with a layer of frozen water, ammonia, and methane, along with a liquid nitrogen layer on its surface.
None. By definition a rocky planet is mostly rock. Venus, by far, has the densest atmosphere of the terrestrial planets, but the planet itself is mostly rock and is similar in composition to Earth.
The planet Saturn could theoretically float on giant planet like Jupiter because Saturn has a lower density than Jupiter due to its composition being mostly gas and liquid. This would mean that Saturn would have the ability to "float" in the atmosphere of Jupiter, similar to how a boat floats on water.
