No, they are much smaller.
A galaxy is bigger than a black hole.
Obviously, the Universe is the biggest of that lot. Next biggest is "galaxy", then solar system, then star, then moon. A comet is usually bigger than a meteorite, but not always.
Some stars are bigger than our galaxy, so probably a star somewhere.
By definition the question is incorrect. There are not only 2 galaxies in our universe, but billions. Each galaxy is a different size and is made up of millions or stars and planets. Our galaxy is called the Milky-Way, and our closest neighbouring galaxy is called the Andromeda galaxy.
Our Universe is bigger, than a galaxy.
Stars do not create supernovas. Supernovas happen to stars. A supernova is when a star, bigger than our own sun, explodes due to the lack of gas they need.
A galaxy is bigger than a black hole.
A Galaxy is far bigger than a nebula.
No!
A galaxy cluster consists of several galaxy groups, each of which in turn contains several galaxies. So no; a galaxy cluster is MUCH bigger than any individual galaxy.
No.
That is impossible. A universe, whether infinite or finite is still vastly bigger than a galaxy.
No. The Milky Way is our Galaxy.
A dwarf galaxy by virtue of it's name will be smaller than a "normal" galaxy.
Yes, much bigger. There are many stars in our galaxy, thousands of millions of them. Everything you see in the night sky is in our galaxy, including the Moon, so the galaxy is much bigger.
Nope! It's smaller than the S3.
