Is it possible for a planet to be made entirely of water?

there are no conditions in the vastness of space that would cause that much water to organize in any shape that looks like a sphere. there are few conditions outside of another gravity well that would cause it to form any other shape.

What planet is made of water?

Earth
Earth is the only planet in our Solar System that has stable bodies of liquid water on the surface. On any other planet (or moon, asteroid, etc.), liquid water would immediately evaporate or freeze.

Do all planets have liquid cores?

Structure. Every inner planet has a core. The cores of Mercury, Venus, and Earth are composed of iron-nickel. Mars’s core is made of liquid iron sulfide mixed with some nickel.

Did Mars have a core?

Mars is differentiated, which—for a terrestrial planet—implies that it has a central core made up of metallic iron and nickel surrounded by a less dense, silicate mantle and crust. Like Earth, Mars appears to have a molten iron core, or at least a molten outer core. Second, its core is richer in sulphur.

What makes a water planet possible?

The component here that makes these planets viable is what is known as ‘hot ice’ – water actually has around 10–12 solid states (only one of which is the ice we know). Under extreme pressure, water molecules take other forms, all of which could act as a solid core for a water planet.

What is the planet made out of?

The planet is completely made out of water (that is, any non-water substance makes up a negligible amount of its mass). There may be a non-water atmosphere above, but there’s no stone or metal center; the water goes down to the center. Most or all of the water on the planet’s surface is liquid…

Can a planet with a liquid water core be stable?

Especially if you place a moon around it for a literal tidal wave circling the planet. As long as you accept an ice core instead of liquid water core there is no issue with stability; once the water world exists it will be stable enough. Although anything that would normally rob a planet of its atmosphere would be a serious issue.

How stable is a planet with an ice core?

As long as you accept an ice core instead of liquid water core there is no issue with stability; once the water world exists it will be stable enough. Although anything that would normally rob a planet of its atmosphere would be a serious issue. How can I make this claim without doing numbers or looking references?
