Have you ever looked up at the night sky and wondered what’s out there? We’re going to take a closer look at stars, and find out which ones are the biggest.

Stars are huge balls of burning gas, and they come in different sizes. Some are larger than others, and our sun is one of them. In fact, our sun is the largest star in our solar system. It is made up of mostly hydrogen and helium, and it gives off energy in the form of light and heat.

But it’s not the biggest star known to us. That honor goes to VY Canis Majoris, which is located in the constellation Canis Major. It is a red supergiant, which means it is much bigger and brighter than our sun. It’s about 3,000 times bigger and about 1 million times brighter.

The second biggest star is UY Scuti, located in the constellation Scutum. It is even bigger than VY Canis Majoris and has a diameter of 2.4 billion kilometers. It is also much brighter, with a luminosity of 5 billion times that of our sun.

And then there’s the star known as RW Cephei, located in the constellation Cepheus. It is a yellow hypergiant, which means it is even bigger and brighter than the two other stars we’ve mentioned. It has a diameter of 1.7 billion kilometers and a luminosity of 30 billion times that of our sun. So, while our sun is a huge star, there are even bigger stars out there. So the next time you look up at the night sky, remember that you’re looking at a universe full of stars, some of them much bigger than our own.
