It also marked a turning point in the multibillion-year history of the solar system. One of the sun's planets had at last evolved a living creature that could break the chains of its home gravitational field...
...Solar Orbit. The earth and moon, whirling around each other, are not alone in space. They also orbit around the sun, and so do the other planets.
