Still waiting for the star size comparison to be better!

Could you update this app and build astrophisics 3 for the app store?

And could you build the star size comparison including planets and Inside Out 2 emotions? You’ll make sure to add the biggest stars as of 2022!

Stephenson 2-18 is the biggest star than Betelgeuse

Can you add these big stars?
