Betelgeuse is a star that swells in size periodically. At its smallest, when it is fully contracted, over 125 million suns could fit inside it. At its largest, the number is 730 million. |
|
|
When Betelgeuse is at its smallest, over 156 trillion earths could fit inside it. At it's largest, 912 trillion earths could fit inside it. |
|
|
Approximately 100 billion or so people have ever been born. So if you gave every person who has ever been born their own earth inside of Betelgeuse, each person would have 9,125 earths to themselves. |

If the sun were the nucleus of a smaller atom such as hydrogen, its electron(s) in the outer shell would be considerably more than 100 billion miles out in space, well over thirty times the distance that Pluto is from the sun. |
