I don't know much about celestial mechanics, but Newtonian conservation of energy should mean that not only did we 'boop the Sun', but we also pushed the Sun a tiny, tiny, tiny bit away from where it was. I wonder if that would be measurable.

- quickthrower2 5y agoWould”t that be true of any voyage through the solar system?
- vbrandl 5y agoIf the vessel was started at day, the earth was also pushed away from the sun
- vegai_ 5y agoCool way to fix the global warming problem. Just push the sun away.

"That's conservation of energy," he says. But no one will notice. The change in Jupiter's orbit around the Sun due to the flyby is fantastically small. New Horizons will absorb about 1/1025 of Jupiter's orbital energy. That's like "taking a single drop out of the ocean," says Farquhar.

- jfk13 5y ago1/1025 of Jupiter's orbital energy sounds absolutely huge. Of course, it's supposed to say 1/10²⁵, which is quite different.
- jnsie 5y agoTHANK YOU!!! I re-read that so many times :-)
- JaimeThompson 5y agoThat was my fault for not double checking my copy / paste. Sorry about that.
- JaimeThompson 5y agoMy fault. I didn't verify it when I pasted it. Thanks for correcting it!
- vikingerik 5y agoI once saw a calculation that Voyager's slingshot past Jupiter slowed the planet's motion by one foot per trillion years. It's measurable, if you've got a long enough time scale.
