equator

Rugby league's international game has some way to go to catch some of its peers, but at least genuine progress is being made to tie up the sport on both sides of the equator.

A rider’s entire journey, including flights, ferries and public transit, must equal a total distance equivalent to 40,000km – the circumference of the Earth’s equator.

The process is linked to how the Earth's rotation affects winds in tropical regions just away from the equator.

Countries close to the equator can experience very high UV levels in the middle of the day, throughout the year.

It was south of the Earth’s equator and had a tropical climate, until it and the rest of the planet became engulfed in ice.
