Hitting a golf shot off the moon..

No. Orbital velocity for the Moon is around 1700m/s, which is beyond the muzzle velocity of a high-velocity rifle, never mind a golfer. (The very hottest rifles typically deliver around 1200m/s, if memory serves.) -- "Think outside the box -- the box isn't our friend." | Henry Spencer -- George Herbert | |

Hitting a golf shot off the moon..
Good morning,
Hail, Michael Smith! We who are about to post salute you. [...] The other problem is that an initial impulse from the surface can not result in an orbit which does not intersect the surface. To achive orbit the golf ball would have to make a circularisation burn (or be whacked by another golf club) after the first half an orbit. Bounce it off the (solar)windmill ;-) Take care, cb -- Christopher A.

No, or at least, not in the sense you probably mean. Even if you could impart enough velocity to it (and I have no idea how hard that would be to do), any orbit ultimately intersects the starting point. Since it starts on the ground, that means it would intersect the ground. Even if it diddn't, low lunar orbit is unstable, and it will be perterbed so that it does. In theory, you could hit the ball to one of the L points. |

Bad guy picks up a rock, throws it at the good guy who ducks at the right moment. Action continues until the bad guy is hit on the back of his head by the same rock, one orbit later. Unlucky for him that he threw it at or slightly above orbital velocity. -- Michael Smith Network Applications www.netapps.com.au | +61 (0) 416 062 898 Web Hosting | Internet Services |

Yes. Provided, you can hit the golf ball with the stick which is several kilometers long.

I think the best you could do is to hit the ball, have it orbit once,
and eventually it would fall back near the spot you hit it. But wouldn't that be cool??? |
