"Eden, Tau Ceti," breathed Gloria. She turned and faced Bertram Harrison. "Junior," she said in a dry, strained voice, "if you'll wear mittens and handcuffs, let's go back in the garden and get acquainted." Her father exhaled a full breath. Mr. Harrison tapped him on the shoulder. "How about a sample of that bottle of natural bourbon?" he suggested. "Not," Mrs. Hanford said shakily, "without me!" IV Man's first sally across the gulf of interstellar space had been more fruitful than his first fumbling exploration of the Solar System by a score of one to nothing. Of all the celestial real estate that orbits around old Sol, only the Earth will support life--at least as we know it. Survival elsewhere depends upon taking enough of Earth environment along to last of the trip. From the scientific standpoint, the first exploration of space was a brilliant operation, but before finding a place to accept the teeming millions of Earth's exploding population, the patient nearly died. For it was a quarter of a century until Murray, Langdon, and Hanover cracked the Einstein barrier. By careful design, and then by counting the last gram and striking a mathematically adjusted balance between power bank and crew space, the range of a spacecraft was found to be slightly more than seventeen light-years to the point of no return. Within seventeen light-years of Sol, there are forty-one other stars. Of these forty-one stars, three are triple-sun systems, and twelve are doubles, which eliminates fifteen of them. Of the remaining twenty-six single stars, one is the blinding-blue giant Altair, two are white dwarf stars, and nineteen of them are the faint red dwarf stars of Spectral Class M, and that eliminates all but four of the original forty-one. Of this remaining four, Epsilon Eridani, Epsilon Indi, and Groombridge 1618 fall into the orange Spectral Class K, which is not too far away from Sol's Spectral Class G. But K is only close; it is no bull's eye when the combination of all the factors must add up to produce a planetary environment that will support human life. And so, having eliminated forty out of the forty-one stars in Sol's neighborhood, only Tau Ceti remains. Tau Ceti is also a Spectral Class G star and therefore Tau Ceti was voted the star most likely to succeed, long before Man had the foggiest notion of how to cross the light-years, long before instruments sensitive enough to ascertain that Tau Ceti possessed a planetary system were developed. Tau Ceti's planetary system can be used as an example of the brilliance of logic and reasoning. The second planet in the family of Tau Ceti is the planet Eden. Eden supports life.
