Enjoyed playing around the visualization to get a better mental picture of Earth's neighborhood. it's mind-blowing to know that there are 200 to 400 billion stars just in our galaxy alone. And it's even more breath-taking to comprehend that our galaxy is but one of a ≥100 billion galaxies in the _observable_ universe.

So about 4 × 10^22 stars in the observable universe, then?

A huge number compared to the number of values that can be stored in a 64-bit integer (1.8 × 10^19).

But a tiny number compared to the number of atoms in a human body (7 × 10^27).
