The asteroid was roughly spherical--which was unusual, but not remarkable. The radar gave him the distance from the surface of the asteroid, and he measured the diameter and punched it through the calculator. "Observe," he said in a dry, didactic voice. "The diameter is on the order of five times ten to the fourteenth micromicrons." He kept punching at the calculator. "If we assume a mean density of two point six six times ten to the minus thirty-sixth metric tons per cubic micromicron, we attain a mean mass of some one point seven four times ten to the eleventh kilograms." More punching, while he kept his eye on the meteorite, waiting for the spot to show up again. "And that, my dear Jules, gives us a surface gravity of approximately two times ten to the minus sixth standard gees." "_Jawohl, Herr Oberstleutnant._" "Und zo, mine dear Chules, ve haff at least der grave zuspicion dot der zurface gravity iss less dan der zentrifugal force at der eqvator! _Nein? Ja!_ Zo." "_Jawohl, Herr Konzertmeister._" Then there was a long, silent wait, while the asteroid went its leisurely way around its own axis. "There it comes," said Captain St. Simon. He kept his eyes on the crosshair of the peeper, one hand over the timer button. When the silver splotch drifted by the crosshair, he punched the stop button and looked at the indicator. "Sixteen minutes, forty seconds. How handy." He punched at the calculator again. "Ah! You see, Jules! Just as we suspected! Negative gees at the surface, on the equator, comes to ten to the minus third standard gees--almost exactly one centimeter per second squared. So?" "Ah, so, honorabu copton! Is somesing rike five hundred times as great as gravitationar attraction, is not so?" "Sukiyaki, my dear chap, sometimes your brilliance amazes me." Well, at least it meant that there would be no loose rubble on the surface. It would have been tossed off long ago by the centrifugal force, flying off on a tangent to become more of the tiny rubble of the belt. Perhaps "flying" wasn't exactly the right word, though, when applied to a velocity of less than one centimeter per second. _Drifting_ off, then. "What do you think, Jules?" said St. Simon. "Waal, Ah reckon we can do it, cap'n. Ef'n we go to the one o' them thar poles ... well, let's see--" He leaned over and punched more figures into the calculator. "Ain't that purty! 'Cordin' ter this, thar's a spot at each pole, 'bout a meter in diameter, whar the gee-pull is _greater_ than the centry-foogle force!" Captain St. Simon looked at the figures on the calculator. The forces, in any case, were negligibly small. On Earth, where the surface gravity was ninety-eight per cent of a Standard Gee, St. Simon weighed close to two hundred pounds. Discounting the spin, he would weigh about four ten-thousandths of a pound on the asteroid he was inspecting. The spin at the equator would try to push him off with a force of about two tenths of a pound.
