What is the size of the Milky Way galaxy compared to other galaxies? Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. That sounds huge, and it is, at least until we start comparing it to other galaxies. Our neighboring Andromeda galaxy, for example, is some 220,000 light-years wide.
How big is Milky Way compared to other galaxies? The Milky Way is an averagely large galaxy with a diameter of 100 000 light years and about 200 billion to 400 billion stars; but compared to larger galaxies like M100, M 87, NGC 4921 or Hercules A, the Milky Way looks like a dwarf galaxy.
Is Milky Way a large galaxy? The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy. Our best estimates tell us that the Milky Way is made up of approximately 100 billion stars. These stars form a large disk whose diameter is about 100,000 light years.
What is the largest galaxy in the universe? Located almost a billion light-years away, IC 1101 is the single largest galaxy that has ever been found in the observable universe. Just how large is it? At its largest point, this galaxy extends about 2 million light-years from its core, and it has a mass of about 100 trillion stars.

The smallest of galaxies contain a “mere” few hundred million stars while the largest galaxies contain up to one hundred trillion stars! Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.
What is the middle of a galaxy called?
The Galactic Center (or Galactic Centre) is the rotational center, the barycenter, of the Milky Way galaxy. Its central massive object is a supermassive black hole of about 4 million solar masses, which powers the compact radio source Sagittarius A*, which is almost exactly at the galactic rotational center.
Can you live on a galaxy?
The Milky Way Won’t Live Forever
The two spiral galaxies are currently hurtling toward each other at 250,000 miles an hour. When they do smash into one another, it won’t be as cataclysmic as you might imagine—Earth will likely survive, and very few stars will actually be destroyed.
How fast is the Milky Way moving towards Andromeda?
