Saturn is less dense than water. So the Answer is Saturn.
A planet's weight does not determine whether it can float in water. It's density is what determines that. Your question should be "Which planet's density is so small that it could float in water?"
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.
Saturn is the least dense planet, only 0.7 g/cc on average (less than water's density). If you could put Saturn in bathwater, it would float.
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).
Earth is the third planet from the Sun and is located in the inner region of the solar system. It is the only known planet to have liquid water on its surface, making it unique in its ability to support life.
Saturn. The planet is less dense than water.
Saturn. It is the only planet in the solar system that is less dense than water.

In the Solar System the answer is Earth since it is the only planet that has water.
Mars is the other planet in our solar system besides Earth that has water.

That is the planet Saturn.
Saturn is the only planet in our Solar System that is less dense than water. Saturn would float if there were a body of water large enough!♥♥
Theoretically, the planet Saturn would float when placed in water because it has an average density that is less than the density of water. On the other hand, there is probably not enough water in the solar system to permit the experiment to be performed. If you choose not to consider the planet as a whole, the atmosphere would float on the water but the rocky core would sink like a stone.
