Some of the interesting facts of different sports in the world are mentioned below. 

1. The Summer Olympics are held once in four years in 1 country. But, twice the Olympics were held in 2 different countries in 1920 and 1956. In 1920, the Olympics were held in Belgium and Netherlands. In 1956, the Olympics were held in Australia and Stockholm.

Although, I'm not the sort of person who is keen about sports (in terms of playing, I do love watching though) but sports facts are always a delight to get to know. You may think that it is only a sport with basic rules and regulations that the players are guided to follow, but that is only the surface. There is a lot more to sports than just the surface game (although that's not any less appealing either) such as the facts listed as follows.

Sports have been played even on the moon

In 1971, Alan Shephard and Edgar Mitchell made history when they became the first people to play sport on the moon. Shephard hit a golf ball while Mitchell threw a makeshift javelin it was actually a staff they'd used in one of their scientific experiments.

On average, a golf ball has 336 dimples

The dimples on a golf ball are designed to make it more aerodynamic, allowing it to travel further in the air. There are no official rules about how many dimples a golf ball can have and most feature between 300 and 500.
