Hi, folks. I'm new here and came looking for some expert input on this odd question that came up as a friend and I were considering a hypothetical. Suppose a hand grenade were orbiting the sun---say, half way between the orbits of Mars and Jupiter. And to make things easy, suppose that the grenade orbiting in the same direction as these other planets, and at a speed generally consistent with that of planetary orbits. What happens to the shrapnel if the grenade explodes? After a time, will we find a large field of scattered shrapnel all moving in the original direction and speed? Will some shrapnel end up on an opposite course from the original course? Will any shrapnel end up orbiting on a different plane than the original (pre-explosion) plane? Will some shrapnel leave the solar system? I realize these are only a few possible results. If anyone can chime in with an answer, I'd sure appreciate it. And if a consensus can be reached, that's even better! Thanks!
