So many science fiction story ideas...
What if planets orbited Earth at the same distance as the ?

- Viewing Jupiter from that angle would be really pretty for the .5 seconds before you got fried by the radiation from its magnetotail. :)Apr 10, 2012
- My immediate thought is that we'd be the ones orbiting Jupiter!Apr 10, 2012
- where 'orbiting' = 'plunging into', unless we're moving fastApr 10, 2012
- Did the quick and dirty, back of the envelope calculation. "Very fast" would be something on the order of 228,000 miles per hour, on average.Apr 10, 2012
- google tells me that's about 3.4 times as fast as we go around the sun. Vroom vroom!Apr 10, 2012
- I'm happy we only have a tiny little moon. No fast plunging doom or magnetotails for me, thanks.Apr 11, 2012
- So I went back this morning and did the slightly-less-quick and dirty calculation. It was WAY dirtier than I thought. Originally, I'd ignored the diminished force of gravity at that distance. (You can actually get away with that for objects in low earth orbit without too much impact.) But at a lunar orbital radius, the acceleration of gravity for Jupiter drops from an impressive 26 m/s^2 to a much less impressive 0.85 m/s^2, and the speed is a less impressive 40,000 mph. Still, even at that speed, the earth would orbit it every 37 hours. Can you imagine having THAT view blot out the sky every day and a half?Apr 11, 2012
- This is so awesome. One of the most effective was to visualize planetary scale I've ever seen.Apr 11, 2012
