as it has on most of the others. To me that will be a sad day because the lumpish term kilometer can never subsitute for the fine old monosyllable mile. But, in case this planet-walk is still in use, it will need a decimal translation. Our basic unit of the yard will have to be translated into the meter. A yard, in origin a pace (a fairly long one), is 36 inches; a meter, in origin 1/40,000,000 of the circumference of the Earth, is 39.27 inches, so we are fairly lucky. The Pacer's legs should stretch a bit more. For our scale, instead of 1: 6,336,000,000, we'll choose the rounder number of 1: 6,000,000,000. Thus, in pacing between the planets, 1 meter (pace) represents 6,000,000 kilometers. In the sizes of the bodies, 1 centimeter represents 60,000 kilometers. This makes the total walk slightly less than a kiloneter (1000 meters). You can call it "about a kilometer." Then a light-year (9,460,530,000,000 kilometers) because in the model 1,600 kilometers, and the nearest star, at 4.22 light-years, is about 6,700 kilometers away.
