The planet, Gliese 581c, circles the star every 13 days at a distance of
about seven million miles. According to models of planet formation developed by
Dr. Sasselov and his colleagues, such a planet should be about half again as
large as the Earth and composed of rock and water, what the astronomers now call
a “super Earth.”
