earth
Obviously the Earth.
Pluto
My planet Earth, which is also your planet Earth, is known for having the best restaurants, the most beautiful women, the most exciting roller coasters, the best chess players, and really, the only life we know of in the entire solar system. We all know it as the planet that we live on.
Uranus
Uranus. But it has to be perfect conditions, no light pollution and you have to know where to look.
Jupiter is the planet with the most moons in our Solar System. As far as the Universe goes, we can barely detect extra-solar planets, so there is no way to actually say what planet in the Universe has the most moons. Since we don't know about all the planets, we *definitely* don't know about all the moons.
Earth is the most habitable planet in the solar system, which is why there is so much life on it. As far as we know, no other planet has life on it. Mars could possibly support human life, with supports to help them.
No. Neptune is the outermost known planet, and it's highly unlikely that there are any more that we don't know about.
Well we know of one that can. With careful observation most people notice it.
No, the sun is not known as a planet!
In terms of its impact on life on Earth, the most important planet is Earth itself. It is the only known planet that supports life as we know it and plays a crucial role in providing the necessary conditions for living organisms to thrive.
Well for starters I know that the Sun in not a planet XD
