Are stars are more than moons in universe?
It's impossible to know for certain whether there are more stars or moons in the universe, but we can speculate. If most stars have planets orbiting them, as it appears they do, then there would logically be more planets than stars. If our solar system is any kind of model, then most planets have at least one moon, therefore there are more moons than planets. If all of the previous holds true, then there are more moons than stars. But again, this is entirely speculative.
Why is that there are more planets and moons than stars in the universe?
Background first, then the answer. First: The Big Bang is a theoretical event that explains the observed data regarding the creation of the Universe. It's very speculative. Second: Theories about Planetary Formation around starts is much less speculative since we have abundant evidence about it happening. Third: According to the Big Bang theory, matter started to condense from the energy cloud shortly after the early moments of creation. The first matter was sub atomic particles. The first atoms to condense where mostly hydrogen. The hydrogen gas clumped and compressed into first generation stars, without planets (because there wasn't any heavy elements to form them). These early stars lived, fussed hydrogen into heavier atoms, aged, and died; leaving behind helium, oxygen, nitrogen, carbon, etc., plus un-fussed hydrogen. This debris then clumped up again (due to gravity) and new stars formed, but this time with planets, made from the heavier elements created in the first generation stars. This cycle continues today. Finally: At this time, it is guessed that most stars in our galaxy have planets orbiting them. They have have multiple planets and moons because as the heavy element collect together in the dust cloud surrounding the new second and third generation stars, if forms up at different orbital locations due to uneven concentrations of the dust around the new stars, and because of minute disturbances from random object that pass near or through the new star system.
Are there more planets in the universe than stars?
If our system is fairly average, then the answer is that there are more planets than stars. If we are an exception (as in, most other stars do not have planets), then there might be more stars than planets.But we are not quite sure yet. Currently we can only detect very large planets (about twice the size of earth), so most planets would probably slip under our radar (we would fail to detect half of the planets of our system). And that’s only if their orbital plane is very specific (they need to pass between their star and us or we are unable to detect them).Based on our current observations, considering all the limitations we have and all the planets we can’t see yet, stars seem to be pretty crowded, so there is a good chance that there are more planets than stars.
Are there any planets or stars in the universe that is not round in shape?
Because of the effects of gravity, all stars and major planets are more or less round. If measured accurately, they are what are called "oblate spheroids": slightly larger at their equator than between the poles, again because of the effects of gravity and their rotational speed. This is most noticeable with Jupiter and Saturn, because they are largely made up of gas and have very rapid rotation periods. There are no cubes, pyramids, etc. Smaller bodies such as asteroids and smaller moons may be irregular in shape, potato-like.
How many planets are there in our universe?
We don’t know, and I am afraid we will never know for sure. I am sorry, but this is true. Maybe we could somewhat estimate , but even that will be pretty rough.The problem is that planets don’t have any light of their own, we can infer their presence (at least currently ) in several ways but they are rather indirect. The most common ones are either by transit method (a planet passes between their star and us and a small dip in the light of the star would signal for us a planet passing) or by wobble method, its gravity will somewhat pull on the star making it slighlty wobble.This means that small planets will be difficult to detect if they don’t pass in front of their (preferably small) companion. Also there are apparently a lot of rogues planets out there. Some studies showed that there might be twice as many rogue planets as stars in the Milky Way or less then the number of stars (but still around 75 billion of them.Statistically speaking there are about 200 billion to 2 trillion galaxies out there and on average there are around 100 million (10^8) stars per galaxy as some studies suggest (How Many Stars Are in the Universe?) . And the number of stars that have solar systems seems to be the rule rather than the exception, at least in the Milky Way. The estimate for number of planets in the Milky Way is at least 100 billion. So about half the number of stars in a galaxy, this is not including the rogue planets.Now, for the time being we are not aware if there are any rogue intergalactic planets (there should be).Punching in those numbers we would get a lower limit of at least ten billion billion planets (1 and 19 zeros) and about 15% of those might be no bigger than Earth size
Why do stars and planets exist?
There’s no strict reason why they exist.The universe is amoral and indifferent to the existence of life.If multiverse theory is true then we’re just one universe which happened to have its “constants of nature” set at values that were hospitable to life.Once these values were set life existing was inevitable.The Big Banged.The stars swirled into being from the primeval dust and fog.They coalesced matter and formed little rock and gas balls that spun around them.Little twitchy life things started jiggling on the surface of one such rock ball.These jiggly things started building lil’ structures.Then they started swimming.Then they stood up.Then they got really angsty and put on some Linkin Park music because DAMMIT MOM YOU DON’T UNDERSTAND ME!!!Life doesn’t exist for a reason, it just does. The only reason life seems inevitable in our universe is because it is. It’s the observer bias. Our data set has one example and that example says life is inevitable because we’re alive to have this bias.Other universes probably don’t have life. Hell if the multiverse is just a “universe” but one order of magnitude above, maybe it’s inhabited by its own lifeforms. Maybe they wonder about their own existence on chat room type social platforms.Or maybe they play pool. Who knows?(I love the internet. Looked up “aliens playing pool” and this Deviantart image popped up.)TL;DRLife exists because in this universe it can, and so eventually it will given enough trials. The universe is massive so enough trials happened and so we both ended up on Quora.

What are the most interesting planets in the Universe?
I'll list few interesting facts about the planets of our own Solar System:Three days (rotation period) on Mercury are nearly equal to its two years (revolution period around Sun).Venus spins in opposite direction as compared to all the other planets in the Solar System, i.e., sun always rises in the west on Venus.Jupiter and Saturn have 67 and 62 known moons respectively.Apparently, Saturn is not the only planet in our Solar System which has got rings. Jupiter, Uranus and Neptune also have thin rings, which are not visible via the usual 8" reflector telescope.The inclination of the Uranus's axis to its ecliptic plane is 98° , i.e., it literally rolls around the sun.Many of you might know that Moon is tidally locked with earth (Its revolution period around the Earth, and it own rotation period are exactly same, that is why we always see the same side of the Moon). But this is not the only example of such a phenomenon, Pluto and Charon, are Mutually tidally locked, i.e., Both have their same face always facing each other. In fact many closer moons of Gas giants demonstrate this kind of gravitational locking.If I recall/find more, I'll add them here.
Why are there so many planets in the universe?
Q: Why are there so many planets in space?Well, it appears that it’s the nature of universes to make hydrogen, which in due course makes stars that explode, leading to other stars that explode, eventually giving rise to planets and to us.At one time it was seriously argued that there must be life on Jupiter, because it has so many moons, and moons are only useful to inhabitants in general and fishermen in particular. I think that was Galileo, but I might have “misremembered”.Speaking of Galileo, the reason he got a kicking from the RCC was that, although he later turned out to be right, at the time he couldn’t actually prove this theory in mathematical, or observational terms. And like Newton, he is said to have been a bit of a git with a talent for rubbing authority up in the wrong way.Generally,on this kind of thing, it’s wise to remember that there’s:The Weak Anthropic PrincipleThe Strong Anthropic PrincipleThe Completely Ridiculous Anthropic Principle.The religiously inclined generally tend to gravitate to the CRAP conjecture. Christ knows why…
Are stars also planets?
A star contains much more mass than a planet, enough that gravitational forces have compressed the matter enough to start a fusion reaction at the nuclear level, radiating the resultant energy out. A planet orbits a star in a regular manner. The sum of a star and it's orbiting planets is called a Solar System. Stars are always much bigger than planets. Also, their content is different. stars are made of mostly hydrogen, which they push together to form helium. this is then pushed together to form other elements which are blown into space. (although one star nicknamed Lucy has got alot of carbon in its core, which because of the pressure has formed a diamond which is a billion billion carats.) planets are different. although they may be made of gas, like Jupiter, they are different gases to the ones in stars. also, it is actually very unlikely that it is made from gases. it is usually molten iron and rock. A star is a burning mass of (mainly) hydrogen and helium. The outer planets are also made out of hydrogen and helium. Neptune and Uranus theirs also have methane,hydrogen, and helium in it that's why both planets are blue. A planet is a body which moves in an orbit around a star. A planet (of any sort, dwarf or other) is defined as "any celestial body which orbits a star." The earth is a planet. A star is typically a big, burning, ball of gas around which planets tend to orbit. (except when it goes out, then it is a black hole or a neutron star.) The sun is a star. Fun fact: The only place gold comes from is supernovas. All gold is made in supernovas.
Are there more planets or stars?
Stars by far.! There are literally billions upon billions in the universe. There are endless numbers of galaxies in the known universe each with countless star systems. Planets however can be reasonably rare in comparison. Recent years more exo planets have been discovered however most of them are unlikely to harbour life..but a few might. Gliese581d being an example. Who knows maybe there are a lot more to find and ET might yet exist. There are many ancient stars in the universe that would have been unlikely to produce a planetary system and also many ancient small red star clusters spread throughout space all pretty unlikely candidates for planet formation.
