***READ THIS BEFORE ASKING ANYTHING***

This is the ultimate size comparison video that you can find on the internet in HD.
Starts with the tinyest dwarf planets of our solar system, then continues with large planets, dwarf stars, stars giant/supergiant/hypergiant stars, nebulae, globular clusters and galaxies.
There is the famous VY Canis Majoris rated as the biggest star known, but very few know that that the incredible IC 1101 is the largest known object in the entire universe. Only galaxy clusters are bigger than it.
Hope you enjoy this one.

FAQ:
-Sizes are not 100% accurate as there is no way to directly measure them.
