Biiiig Star

To little critters such as ourselves, the planet we live on seems big. But compared to our planet, our sun is bigger still. But compared to other stars, such as the red supergiant Betelgeuse, our entire solar system is small. Replace the sun with Betelgeuse, and everything inside Saturn is quite literally toast.

Betelgeuse, in fact, has the habit of emitting arcs of superheated gas that are, all by themselves, almost as large as the orbit of Neptune.

What are humans that You are mindful of them, indeed.
