Take some with you. I don't know of any other planets with observable oxygen at enough concentration to support human life. Mars MAY have a very very very light atmosphere, but not much and certainly not enough to breath. Venus is 800 degrees and the atmosphere is mostly carbon monoxide and sulphuric acid, also not so pleasant. Among other methods, oxygen is produced by photosynthesis of green plant life taking in sunlight and converting carbon dioxide (what we breath OUT) and releasing OXYGEN (what we breath IN). So your planet would need to have enough leafy green plants and enough sunlight for this to work
If we discovered water on another planet, it means that humans may be able to inhabit that planet. It would be a big break through for scientists. Another answer may be that other organisms or bacteria may be able to live on that planet, meaning there could be life on another planet but Earth.
The only planet with oxygen (known to Man) is Earth.That is to say, only Earth has a significant amount of the element oxygen in its atmosphere.Other planets do have oxygen, but it is chemically combined in the form of compounds, like carbon dioxide.
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?"
It would need a source of food and water. It would also need a form of shelter from whatever weather the planet might have. In addition to food and water, life needs oxygen in a form it can use, enough pressure to keep the life from blowing apart and from its liquids boiling away without being enough to crush it, an environmental temperature that is not cold enough or hot enough to kill the life, and protection from harmful solar radiation.
lunar The moon is a satellite. Meaning it orbits another planet.
In a way, yes, if there is not enough oxygen getting to it, and there is an excess of non-vital fluids in your bloodstream, your brain could be considered as drowning. Alternatively, if you are inhaling gas that is not oxygen, or another fluid that is not oxygen, your brain could be considered as drowning.
Without a suit? No, the planet's atmosphere is thin and without oxygen.
It wouldn't survive being on the moon just like any other living thing. Anything that breathes oxygen can only survive on earth unless their is another planet with oxygen.
Some scientists believe that it is possible to establish a colony on Mars and we could but we would have to wear space suits and grow lots of oxygen creating plants. The atmosphere is strong enough to hold the oxygen.

If a nova were to get close enough to a planet, there's no doubt in my mind it could. if it were a planet around the size of earth easily. A bigger planet would be more difficult, but yes. a nova can wipe out a planet.
No. All planets have gravity. Any object massive enough to be considered a planet would have strong enough gravity that you could simply escape by jumping. It is, however, possible for an object to escape the gravity of any planet if it is launched in the right way and with enough speed.
Saturn
No. Too cold, no oxygen, too much pressure.
Nobody one knows since our primates could have evolved differently on that planet.Or if the planet has oxygen and also if the planet has gravity
remaining oxygen would be used up
