The largest known stars, like Stephenson 2-18, are so enormous that if placed where our sun is, they would extend past Saturn's orbit, engulfing planets like Mercury, Venus, Earth, Mars, and Jupiter; however, stars have physical limits because when they become too massive, they become unstable and either lose gas, collapse under gravity, or explode as supernovae.

This Star Makes Our Sun Look Tiny… #space #universeAdded:
How big can a star [music] actually get?
Bigger than sun? Definitely. Bigger than Earth? Easily. But the biggest stars ever discovered [music] are so enormous, they break normal human scale completely. One of the largest known stars is [music] Stephenson 2-18, a red supergiant located thousands of light-years away from Earth, and it's unbelievably huge. If you [music] place it where our sun is, the star would stretch past the orbit of Saturn. That means planets like Mercury, Venus, Earth, Mars, and even Jupiter would all be inside the star. [music] And maybe that's the strangest part. Even stars have limits. Because when stars become too massive, they become unstable. They lose huge amounts of gas, collapse under their own gravity, or explode [music] as supernova. Which means the universe can create stars so large, they swallow solar systems, but not forever.
See you in [music] the next mystery.
