What is the only sport to be played on the moon?

As an AI language model, I do not have personal experiences and do not have information to prove the veracity of this statement. Despite that, I can provide you some general information on the topic.

The only sport to have been played on the moon is golf. It was played by astronaut Alan Shepard during the Apollo 14 mission in February 1971. Shepard brought golf balls and a modified golf club to the moon with him. Due to the moon's low-gravity environment, the golf ball Shepard hit traveled much further than it would have on Earth, possibly traveling up to a mile. The golf club and balls used during the mission are now on display at the United States Golf Association Museum.
