"I should say it was a wanderer!" Venza exclaimed. "Coming from heaven knows where beyond the stars, swimming in here like a comet."
"They calculated its distance yesterday at some sixty-five million miles from Earth," I said. "It isn't so far beyond the orbit of Mars, coming diagonally and heading very nearly for the Sun. But it's not a comet."
The thing was indeed inexplicable; for many weeks now, astronomers had been studying it. This was early summer of the year 2070 A.D. All of us had recently returned from those extraordinary events I have already recounted, when we came close to losing Johnny Grantline's radiactum treasure on the Moon, and our lives as well. My ship, the Planetara, in the astronomical seasons when the Earth, Mars, and Venus were within comfortable traveling distances of each other, had carried mail and passengers from Greater New York to Ferrok-Shahn, of the Martian Union, and to Grebhar, of the Venus Free State. Now it was wrecked on the Moon.[1]

I had been under navigating officer of the Planetara. Upon her, I had met Anita Prince, whose only living relative, her brother, was among those killed in the struggle with the brigands; Anita and I were soon to marry, we hoped.
I was waiting now in Greater New York upon the decision of the Line officials regarding another spaceship. Perhaps I would have command of it, since Captain Carter of the Planetara had been killed.
It was a month or so before that adventure, April, 2070, that this mysterious visitor from interstellar space first appeared upon our astronomical horizon. A little thing, at first, a mere unusual dot, a pinpoint on a photo-electric star diagram which should not have been there. It occasioned no comment at the time, save that some thought it might be another planet beyond Pluto; but this was not taken seriously enough to get into the newscasts. None of us had heard about it as late as May, when the Planetara set out on what was to be her final voyage.
Presently, it was seen that the object could not be a planet of our solar system; Coming in at tremendous speed, it daily changed its aspect, gathering velocity until soon it was not a dot, but a streak on every diagram-plate.
In a week or so the thing passed from an astronomical curiosity to an item of public news. And now, early in June, when it had cut through the orbit of Jupiter and was approaching that of Mars, fear was growing. The visitor was a menace. No astronomical body could come among us, with a mass as great as a fifth of the Moon, without causing trouble.
The newscasters, with a ready skill for lurid possibilities, were blaring of all sorts of horrible events impending.
