You sure had to pull strings to get the Frankly, I don't get it! Eros must have terrific mass to have the attributes of a full-sized planet." Bobby jumped. It was Mom's voice.

We forgot to consider the diurnal revolution." "And now we've got to land in the dark. On strange terrain. Arragh! I should have my head examined. I've got a plugged tube somewhere!" Grampaw Moseley hobbled in, appraised the situation with his incomparable ability to detect something amiss. He snorted and rattled his cane on the floor. "They's absolutely nothin'," he informed the walls, "to this hereditation stuff. Elst why should my own son an' his son be so That was sheer optimism.

It's tough. A little bit of luck—" But there was perspiration on his forehead, and his fingers played over the control banks like frightened moths. There was no further need for the artificial gravs. Eros exerted, strangely, incredibly, an attractive power almost as potent as Earth's. sound died away from the cabin, Bobby heard the high scream of Through howling Bedlam they tumbled dizzily and for moments that were Eleanor cradled The Pooch closer to her. Grampaw scowled. And instinctively Bobby braced himself for a shock. But there was only a shuddering jar, a lessening of the roar that beat upon their eardrums, a dull, flat thud.

And floated upward, feeling an uneasy, quibbly feeling in his stomach. Almost immediately a hard something rolling hills beyond. In the sudden scarlet of dawn, it was impossible to believe the night huddled together there on the beach, waiting, silent, wondering. But The night did not last long. But Pop had told them it would not. "Eros rotates on its axis," he explained, "in about ten hours, forty minutes, Earth time measurement. Therefore we shall have 'days' and 'nights' of five hours short dawns or twilights. This will vary somewhat, you understand, with the change of seasons." Dick asked, "Isn't that a remarkably slow rotation? For such a tiny planet, I mean? After all, Eros is only one hundred and eighty odd miles in circumference—" "Eros has many peculiarities. Some of them we have discussed before. It approaches Earth nearer than any other celestial body, excepting Luna and an occasional meteor or comet. When first discovered by Witt, in at aphelion it is far outside. "During its near approach in 1900-01, Eros was seen to vary in brightness at intervals of five hours and fifteen or twenty minutes. At that time, a few of the more imaginative astronomers offered the suggestion that this variation might be caused by diurnal rotation. 1975, the period of its next approach, that the Ronaldson-Chenwith expedition visited it and determined the old presumption to be correct."

"But we can't do it in a day or a week. It will take time." "Time," said Pop easily, "is the one commodity with which we are over-supplied." He thought for a minute. "If that's the way it is, we might as well move."
