Unfortunately, there isn't a specific number that I can give you regarding the number of moons in space. The best answer is probably an infinite amount. Space is hard to put limits of "space" on, because there is a difference between how many moons could be in the observable universe vs. how many moons are in the entire universe. We have no idea how large the entire universe is (likely infinite), but we believe the observable universe to be in the ballpark of 92 billion light years in diameter. Of course that number will continue to get bigger as more light from the expanding universe reaches us.
For "simplicity" let's just take the observable universe. Stars are contained within giant clusters of stars called galaxies. Galaxies contain hundreds of billions of starts and there are hundreds of billions of galaxies within the observable universe. That's a lot of stars. Recently, astronomers released a statement/analysis that claims there is likely at least one planet orbiting each and every star. That's a lot of potential planets to have possible moons.
Not every planet is guaranteed to have a moon. Mercury and Venus have none. But the remaining planets in our solar system have one or more. In fact NASA lists 146 confirmed moons in our solar system and 27 that are awaiting confirmation. That's an average of 24 moons per planet within our solar system. So if other stars have similar setups then the number of possible moons "in space" is more or less impossible to calculate.
Of course, if your question is just asking about our solar system, then 146 moons.
The earth's natural satellite that shines by the sun's reflected light, revolves about the earth from west to east in about 291⁄2 days with reference to the sun or about 271⁄3 days with reference to the stars, and has a diameter of 2160 miles (3475 kilometers), a mean distance from the earth of about 238,900 miles (384,400 kilometers), and a mass about one eightieth that of the earth.
Moons -- also called satellites -- come in many shapes, sizes and types. They are generally solid bodies, and few have atmospheres. Most of the planetary moons probably formed from the discs of gas and dust circulating around planets in the early solar system.
The Sun together with the nine planets, their moons, and all other bodies that orbit it, including asteroids, comets,meteoroids, and Kuiper belt objects. The outer limit of the solar system is formed by the heliopause.
Number of moons in space:-
There are 166 natural satellites in our solar system. Moons divided amongst the planets:-
Mercury and Venus 0.
The number of known moos has been steadily growing with the improvement of technology.
Moons of our solar system
1. Earth's Moon
We could never know exactly how many moons are in space, but there is a pretty good estimate for the moons just in our solar system. According to NASA, there are 146 confirmed moons in the solar system and 27 are waiting to be confirmed as moons. The moons of dwarf planets and the moons that orbit things like asteroids are not included. NASA's definition of a moon is as follows:
"They are generally solid bodies, and few have atmospheres. Most of the planetary moons probably formed from the discs of gas and dust circulating around planets in the early solar system."
It is likely more moons will be discovered in later years.
There's no real answer to that, since our universe is so large and ever-expanding that it would be hard to count or even estimate how many stars there are. However, we do know the number of moons that orbit each of the planets in our solar system, and how many total moons that is. There are 146 moons in our solar system, and many of those moons are Jupiter's moons. And only one of those moons is ours.
