Alan Shepard is the only person to hit a golf ball on the Moon. During the Apollo 14 mission he fitted an 8 iron head to the handle of a lunar sample collection device and launched three golf balls. They are still there!
Although Shepard was only the 5th person to walk on the moon, he was the first and the only to play golf there. During the mission he hit two golf balls on the lunar surface and dug one in the dirt whle hitting it.
NASA seems like a legitimate information source, yet some claim that there are only two golf balls on the moon and that the hits were made with an 6 iron head. But to be fair, this doesn't change the amazing fact that some golf balls are still on the moon, the count of them is trivial.
