VY Canis Majoris is the largest known star in the universe, being around one billion times bigger than our sun — which is one million times bigger than Earth — which in turn is already pretty immense. If it were to replace our sun, the star’s surface would reach up to Jupiter or Saturn. Imagine how the individual human matches up? We could scarcely register the scale of it all in our minds, much less physically grasp it with our senses.
The following short video further emphasizes how mindbogglingly vast our universe is — and how infinitesimally small we are by comparison.
