This helped me visualize how close LEO satellites are, as well as how far away others are (e.g. GPS). http://upload.wikimedia.org/wikipedia/commons/8/82/Orbita

  You're misreading the chart, take another look. The moon is 10x further.

  Not quite, according to that graphic the moon is nearly 10x further away than the GEO distance

Cool! Quick back-of-the-napkin indicates that the RTT for LEO satellites (at the upper bound) would be only ~4.7% of the RTT for GEO satellites. I'm sure there's much more to the story that I'm missing, but an LEO satellite should have a latency of around 11.75ms. In 2012, average US latency to Google was ~50-60ms [1]. Would bandwidth be the limiting factor? [1] https://www.igvita.com/2012/07/19/latency-the-new-web-performance-bottleneck/ https://www.igvita.com/2012/07/19/latency-the-new-web-perfor...
