How big is the milky way
How big is the entire Milky Way?
about 100,000 light-years
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 many miles is the Milky Way galaxy?
600,000 trillion miles
The Milky Way is approximately 100,000 light-years across, or 600,000 trillion miles (950,000 trillion km). We do not know its exact age, but we assume it came into being in the very early universe along with most other galaxies: within perhaps a billion years after the Big Bang.
How big is the Milky Way in comparison to the universe?
The observable Universe is 93 billion light-years, yet, our galaxy, the Milky Way, is just 100,000 light-years in diameter. It would take us endless generations just to explore our galaxy, let alone the Universe. Another ancient structure is the galaxy supercluster known as the Hyperion Supercluster.
Is the Milky Way a large galaxy?
The Milky Way is only a medium sized galaxy with an estimated 200 billion stars. The largest galaxy we know of is called IC 1101 and has over 100 trillion stars.
What is the largest galaxy in the universe?

Where is Earth in the Milky Way galaxy?
Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy.

What is the biggest thing in the Milky Way galaxy?
The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!
What is bigger than the Milky Way?
But the Andromeda galaxy is a whole separate galaxy, even bigger than our Milky Way. In a dark sky, you can see that it’s big on the sky as well, a smudge of distant light larger than a full moon.
Are most galaxies bigger than the Milky Way?
The Milky Way is actually above-average in size but is the second-largest galaxy in the Local Group, which has 30 galaxies. That means that it is still pretty big but not much bigger than most of the other galaxies in our known universe.
