How big is the universe?

Look at that tiny blue marble at the bottom. That’s Earth, our home planet. It feels huge when you’re walking to school, right? But now, let's zoom out! See the glowing yellow ball above it? That’s the Sun. Our Earth is just a tiny speck circling that star. Together, they make up our Solar System.

Ready to go even bigger? Follow the path up to that giant, glowing swirl. That is the Milky Way, our huge galaxy. It is a massive collection of billions of stars. If our Sun was a single grain of sand, this galaxy would be an entire beach!

Finally, look at the very top. See those tangled webs of light? That’s the Universe. It contains every galaxy and everything that exists. From way up here, our entire planet is actually too small to see. You are a tiny part of something so big it never ends. Tiny Concepts.
