It's a question on my science homeworksheet. The hardest of all the questions is this one. I can't find the answer with my information.

None of them. Days on all the gas giants are all under 18 hours. Earth is the largest of the rocky terrestrials, the other 3 all have days longer than 24 hours, only Mars has moons.
Surprisingly the 4 gas giants are much nippier than the 4 terrestrial rocky planets
Jupiter 9.925 hours
Saturn 10 hours 47 minutes 6 seconds
Uranus 17 hours 14 minutes 24 seconds
Neptune 16 hours 6 minutes
as compared to
Earth: 23 hours 56 minutes
Mars 24.623 hours
Venus: 243 days
Mercury 58 days 15.5 hours
Which is rather like Sumo Wrestlers winning the 100 yards sprint!
Pluto isn't larger than Earth so that rules that out.
We do not know if any of the 241 exoplanets we have discovered have got moons yet. So logically this has to be a solar system planet. But there is none that meets all three criteria.
I suspect that you may have mistyped "larger than Earth" when the question said "smaller than earth" and then the answer is Mars. But if you did not make a mistake in typing out the question, there is no answer to it.

NONE of them! The only object that would even come close would be the sun, but it's not a planet and the planets shouldn't be considered moons.
Adding to this after seeing some other answers: None of the outer planets have a day that is longer than ours, except for Pluto, which is much smaller than the earth and isn't considered a planet anyway.

If one wants to explore space, water being as dense as it is, is something you want to have at the end of the voyage so you do not have to tote along water for the entirety of trip to the destination, dwell time at the destination and the return home. As for water on earth- it is the results of politics. Refine a reverse Osmosis system that utilizes the water fully, and you will be a very rich man.

That is seriously easy to research. For example, you can type "length of day on

I'm not going to give you the full answer, since this is homework. I will give you a clue. It's some of the planets farther out in our solar system, most of the planets are made up of gas. Good Luck!

just a guess, but just about every planet outward from the Earth

try anything other than the inner planets and Jupiter(most Apt should be Neptune)
