That would almost certainly have to be Mercury. The intense heat would boil off any volatiles like water during the formation of Mercury, as well as rapidly boiling off any water that arrived in any comet or meteor impact. Mercury is also extremely small with minimal gravity and virtually no atmosphere, which would also lead to extremely rapid loss of any water.
Venus is the only other planet closer to the sun and hotter than the earth, and it's thick atmosphere does hold plenty of water vapor, and there is almost certainly quite a bit of water trapped within the rocks under the surface.
Mars certainly has water trapped in the subsurface rock, the gas giant planets have and hold water within in their thick heavy gravity atmospheres, and icy bodies like Pluto have abundant water-ice. When things are that cold, water in the form of ice is essentially a rock or mineral.

What is the lightest planet in solar system?
The least massive of the 8 major planets is Mercury. However, Saturn, with its large, deep atmosphere, is the least dense of the planets, and would actually float in water (given a really big container of water).
What gasses are in the solar systems atmosphere?
Hydroyen,helium,Iron,carbon moxide,water,sodim and calcim
How many planets in the solar system have oceans of water?
Earth is the only planet in our solar system known to have significant bodies of liquid water on its surface. Some of Jupiter's moons, like Europa, Ganymede, and Callisto, are believed to have subsurface oceans of liquid water.
Four largest planets of solar system?
The four planets in our Solar System are:MercuryVenusEarthMarsIf you want to know the rest of the planets here they are but they are not in our Solar System, after mars is:JupiterSaturnUranusNeptunePluto comes after Neptune but Pluto isn't known as a planet, it is known as a rock because all it is made out of is rock and is so tiny!Thank you for reading :D x
How do the gas planets differ from the inner planets of the solar system?
The terrestrial planets are composed primarily of silicate rocks or metals. They have a solid surface. The gas giants are composed mostly of hydrogen, helium, and water existing in various physical states.
How many planets in the solar system have water?
Scientists believe that at least three planets in our solar system have water: Earth, Mars, and Jupiter's moon Europa. Additionally, other moons in the solar system, such as Enceladus and Ganymede, are thought to have water in various forms.
What planet is the least dense of the planets?
Saturn is the least dense of the gas giants, even out of all of the planets in our solar system. Its average density is around 0.7 g/cc (less than water).
What is the difference between the inner and distant solar system?
In the inner solar system, the planets are rocky and it is possible to have water as a vapor or a liquid on the surface. In the outer solar system the planets are gas giants and water can only exist as ice.
How many planets have oceans that have water?
Eath is the only one known, and most likely the only one, at least in our own solar system
What is the lightest planet in solar system?

How many planets have scientist found?
the amount of planets in this life-system has not yet been found but many scientist are still trying to find out do to mars water roots
What planets have water ice polar ice?
Although there are speculations of ice caps on several moons and planets outside of the solar system, the only confirmed planets within our solar system to possess them are Earth and Mars.
What planets in the solar system have water?
Earth and mars. Mars' water can only be a gas and a solid.
Is it possible to have an all water planet?
Sure There are planets in our solar system that have 100% liquid surfaces, why not water.
