I think the proper energy to calculate is that of an object falling into the Sun, being intercepted in its fall by the object it impacts.

- jaggederest 5y agoSolar escape velocity near Jupiter orbit is only around 18km/s which is quite a bit less than Jupiter's own escape velocity.
- lumost 5y agoObjects aren’t falling into the sun from infinity, as gravity decays according to an inverse square law the sun imparts relatively little kinetic energy to a Jupiter impactor relative to Jupiter.
- dhimes 5y agoTo match the calculations by JPL/NASA, assume that the objects are falling into the Sun from infinity.
