170 moons in our solar system. In terms of the universe, the question is not answerable and probably never will be answerable. 1.7 septillion is just an estimate. We will never be able even to observe every single galaxy in the universe, let alone count the moons that exist around their planets. We might come up with an estimate of the number of moons in the universe, after we get a better grasp of the planetary situation in our own Milky Way. We have just begun the process of observing planets outside of our own solar system. We are far from understanding how many planets and moons there are right here in our own universal neighborhood (The Milky Way).
There are 178 known moons in the Solar System. The planet which has the most natural satellites is Jupiter with 66. There are also 104 asteroid moons and as many as 58 satellites of potential dwarf planet candidates.
Major Planets (171)
Dwarf Planets (7)

We've only just begun to get our heads around how many stars there are in the Universe, and even then we're not too sure but guessing at 10 sextillion. (x)
We've only just begun to see how many exoplanets there are, and not even begun to look at exomoons!!
If we extrapolate as our Solar System as a base model then:-
x = stars, y = planets (inc dwarf), z = moons we get 1, 13, 168.
So X x Y x Z = 2,184,000,000,000,000,000,000,000 moons.
But that's just a guess, there may be two or three more.
In reality, the question is not answerable and probably never will be answerable. We will never be able even to observe every single galaxy in the universe, let alone count the moons that exist around their planets. We might come up with an estimate of the number of moons in the universe, after we get a better grasp of the planetary situation in our own Milky Way.

We don't know for sure. There are well over a hundred, but it's probable, even likely, that the outer planets have a few small ones that haven't been discovered yet.
If we just consider "large" moons, then the answer depends on how big "large" is. Setting the cutoff at 250 km, there are 23: Mercury 0, Venus 0, Earth 1, Mars 0, Jupiter 4, Saturn 8, Uranus 5, Neptune 3. If you've been adding as we go, you'll notice that's only 21: the dwarf planets Pluto and Haumea each have a satellite of over 250 km diameter as well.
No, there are not 2000 moons in the universe. Our solar system has over 200 moons, but there are many more moons in other planetary systems in the universe. The total number of moons in the universe is not precisely known, but it is certainly much larger than 2000.
Our moon, Luna, is indeed similar to many other moons even in our own solar system, much less the universe as a whole (which has not really be examined in sufficient detail to enable us to catalog moons in other stellar systems).
It's actually very difficult to tell this, most moons on far away planets can not yet be seen and just because the planet is earth like doesn't mean it has a moon, or many moons
That would include: Sun Mercury Venus Earth Mars and its moons Jupiter and its moons Saturn and its moons Neptune and its moons Uranus and its moons Pluto and other planetesimals and their moons Asteroids Comets
I'm not sure where you got that idea, but there is certainly not only one moon in the universe. Our planet only has one moon, but most planets have several moons. You should do a search online for moons and look at some examples.
Yes. There are countless planets and moons in the universe.
No, there are not 2000 moons in the universe. Our solar system has over 200 moons, but there are many more moons in other planetary systems in the universe. The total number of moons in the universe is not precisely known, but it is certainly much larger than 2000.
Not only Saturn and Jupiter have many moons, there are many planets that can have many moons because there are many solar system s in the Universe except ours.

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.
Yes
