    In a discovery that they described as a milestone in the quest to find out if
    humans are alone in the universe, astronomers announced yesterday that
    they had found the smallest planet yet outside the solar system.

    With a mass only seven times that of the Earth, the new planet is probably a
    ball of rock, its discoverers said. Orbiting closely to a dim red star in Aquarius
    known as Gliese 876, it is the third and innermost member of a shrunken
    version of our own solar system.

    "This is by far the most Earth-like planet ever found," said Dr. Geoffrey Marcy
    of the University of California, Berkeley, a member of the team that made the
    discovery using one of the giant 10-meter diameter Keck telescopes in Hawaii.
