I cannot even start to grasp the meaning of 100B planets.
I read that if the "Milky Way" was the size of China, then the the sun and 6 closest planets around together would be the size of one quarter.
- InclinedPlane 15y agoI just did the math on that, it's about right. It's closer to a dime though.

- InclinedPlane 15y agoIt's straightforward math, the hardest part is coming up with a width for China (I ended up using an approximation of 5,000 km), all of the other figures are on wikipedia (radius of Saturn's orbit, size of the milky way). Also, if you want to be super lazy you can get google to convert units for you: https://www.google.com/search?ie=UTF-8&q=2.87+billion+km+%2F+100%2C000+ly+*+5%2C000+km#sclient=psy-ab&hl=en&source=hp&q=2.87+billion+km+%2F+100%2C000+light+years+*+5%2C000+km&pbx=1&oq=2.87+billion+km+%2F+100%2C000+light+years+*+5%2C000+km&aq=f&aqi=&aql=&gs_sm=e https://www.google.com/search?ie=UTF-8&q=2.87+billion+km...
