The estimated number of satellite galaxies, given that there are 100 billion galaxies in the universe, is 170 billion.
The estimated number of galaxy mergers, given that there are 100 billion galaxies in the universe, is 100 billion.
The estimated number of galaxy groups, given that there are 100 billion galaxies in the universe, is 100 to 200 billion.
There are approximately 7 trillion dwarf galaxies in the universe.
There are at least 15 billion elliptical galaxies in the observable universe, at distances up to 13 billion light years.
There are at least 5 billion irregular galaxies in the observable universe, at distances up to 13 billion light years.
There are at least 20 billion lenticular galaxies in the observable universe, at distances up to 13 billion light years.
Ten superclusters.
The observable Universe is estimated to have around 1011 (a hundred billion) galaxies. The entire Universe is much bigger than that, but it isn't known how much bigger. Perhaps it is infinite, in which case it might have an infinite number of galaxies.
It is estimated that there are about 100 billion galaxies in the observable universe. However, the total number of galaxies in the entire universe could be much larger and currently unknown. The universe is vast and constantly expanding, so the exact number of galaxies it can hold is difficult to determine.
It is estimated that there are around 100 billion galaxies in the observable universe. As for stars, there are estimated to be around 100 billion stars in our Milky Way galaxy alone. The total number of stars in the universe is difficult to determine, but it is likely in the order of trillions to quadrillions.
There's an impossible way to classify all the shapes of 100 billion galaxies in the universe.
