    The object first catalogued as 31/439, according to the year and the order of its discovery, was detected while it was still outside the orbit of Jupiter. There was nothing unusual about its location; many asteroids went beyond Saturn before turning once more toward their distant master, the Sun. And Thule II, most far-ranging of all, traveled so close to Uranus that it might well be a lost moon of that planet.

    But a first radar contact at such a distance was unprecedented; clearly, 31/439 must be of exceptional size. From the strength of the echo, the computers deduced a diameter of at least forty kilometers. Such a giant had not been discovered for a hundred years. That it had been overlooked for so long seemed incredible.

    Then the orbit was calculated, and the mystery was resolved-to be replaced by a greater one. 31/439 was not traveling on a normal asteroidal path, along an ellipse which it retraced with clockwork precision every few years. It was a lonely wanderer among the stars, making its first and last visit to the solar system-for it was moving so swiftly that the gravitational field of the Sun could never capture it. It would flash inward past the orbits of Jupiter, Mars, Earth, Venus, and Mercury, gaining speed as it did so, until it rounded the Sun and headed out once again into the unknown.

    It was at this point that the computers started flashing their "We have something interesting" sign, and, for the first time, 31/439 came to the attention of human beings. There was a brief flurry of excitement at Spaceguard headquarters, and the interstellar vagabond was quickly dignified by a name instead of a mere number. Long ago, the astronomers had exhausted Greek and Roman mythology; now they were working through the Hindu pantheon. And so 31/439 was christened Rama.

    For a few days, the news media made a fuss over the visitor, but they were badly handicapped by the sparsity of information. Only two facts were known about Rama: its unusual orbit and its approximate size. Even this last was merely an educated guess, based upon the strength of the radar echo. Through the telescope, Rama still appeared as a faint, fifteenth-magnitude star-much too small to show a visible disc. But as it plunged in toward the heart of the solar system, it would grow brighter and larger month by month; before it vanished forever, the orbiting observatories would be able to gather more precise information about its shape and size. There was plenty of time, and perhaps during the next few years some spaceship on its ordinary business might be routed close enough to get good photographs. An actual rendezvous was most unlikely; the energy cost would be far too great to permit physical contact with an object cutting across the orbits of the planets at more than a hundred thousand kilometers an hour.

    So the world soon forgot about Rama. But the astronomers did not. Their excitement grew with the passing months as the new asteroid presented them with more and more puzzles.

Also, this paragraph from Stanislaw Lem's book Fiasco, which I'm reading at the moment:

    They would land, but first turn the Hermes into a comet. Out of valves in the hull that opened along the sides came a foam from tanks; inflated by injections of gas, the foam surrounded the entire vessel with a large cocoon of irregular, hardened bubbles. The Hermes, like a pit in a fruit, lay in a spongy mass of globules. Even from up close it looked like an elongated chunk of rock covered with craters. The burst bubbles made the surface resemble the crust of an asteroid bombarded for centuries by dust clouds and meteors. The drive, indispensable, would be the tail of the comet, which, as it approached the perihelion, would always be directed away from the sun, an illusion created by the drive deflectors. A precise spectral analysis would have revealed, of course, a pulse and composition of gases not found in any comet. But nothing could be done about that.

I haven’t read it yet, so I don’t know if there’s an outcome, but something we cannot dismiss would be the most gentle form of first contact.

Naaah it cruised through and lobbed a singularity kernel at the center of the Earth to bring about our timely destruction. Just ask Greg Bear or David Brin.

And the fact that you haven't read Arthur C Clarke's The Pale King is criminal. You could finish it in two flights.
