The planetsall revolve around the sun in the same direction and in virtually the same plane. In addition, they all rotate in the same general direction, with the exceptions of Venus and Uranus. These differences are believed to stem from collisions that occurred late in the planets' formation....
Then Mercury, who performs a revolution round the Sun in 88 days, 23t hours, which makes the length of his year: his distance from the Sun is about thirty-six million miles. He is a small planet, shining with a pale bluish light; but as he is never more than about 30 degrees from...

Earth-Sun distance. The gravitational effect of a distant passing star is thought to send an occasional Oort cloud comet into a highly eccentric orbit that carries it toward the Sun. However, only a tiny portion of the Oort cloud comets have orbits that bring them into the inner solar ...
remaining 0.15 percent.The planets, in order of their distance from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.Under the control of the Sun's gravitational force, each planet maintains an elliptical orbit and all of them travel in the same ...
Finally, life could evolve only if the planet is just the right distance from its sun. With a weaker sun than our own, the planet would have to be closer to it. With a stronger sun, it would have to be farther away. If we suppose that every star in the universe has a family of...
