rock dust water
There is no known planet that would be able to float in water, as planets are much larger and denser than water. However, hypothetical lightweight planets made of less dense materials like ice or certain gases could potentially float in a giant body of water if it existed on a massive scale.

Saturn is the second-largest planet in the solar system and also the least dense planet. It is less dense than water. In other words, if there was a big enough bath tub, Saturn would float in it.
Hope I could help ^_^The simple fact is, there is no body of water large enough to float a planet in, but also, some planets are made of gas, and the atmosphere would rip the planet apart, and the ones made of rock would most likely sink.
No, Pluto is a dwarf planet made primarily of rock and ice, so it would not float in water. The density of Pluto is much higher than that of water, so it would sink if it were placed in a body of water.
Asteriods are made up of rocks, dust,and minerals that float in spaces atmosphere.
planet 78 is a made up planet by a boy. it has green dust on the ground and is very big
A fork can float if it is made of the right material. A fork that is made from stainless steel will not float in water, but a fork made of plastic will.
Saturn.
It has faint rings which are made of dust.
