== True trip "around the world" ==
To make the longest distance trip around the planet, a traveler would have to pass through a set of antipodal points. ''All meridians'' can be crossed in one hemisphere—indeed, this is possible by walking in a circle around one of the poles—but such trips are shorter than a minimum circumnavigation. On the other hand, the greatest straight line distance that could in theory be covered is a trip exactly on the Equator, a distance of {{convert|40075|km|mi}}. The Earth's [[equatorial bulge]] makes this slightly longer than a north–south trip around the world along a set of meridian lines, which is a distance of {{convert|40008|km|mi}}. Any other closed [[great circle]] route starting on the equator and traveling at an angle between 0° (an equatorial route) and 90° (a polar route) would be between {{convert|40075| and |40008|km|mi}}. In all of these cases, after half of the world has been traversed, every subsequent point will be antipodal to one already visited.
